- In this video, I walk through the basic differences between CAT 8 and CAT 7 as well as how to terminate CAT 8 cables. We will cover the cost, speed, and physical difference and terminate both an RJ45 and Keystone. Not everyone needs CAT 8 but it is nice to know it's there and what it is used for.

Who doesn't love cat videos? :-D
Who doesn’t love dad jokes!
Were you looking for a cat video and found this by accident 🤔
I was today years old when I learned there was anything past CAT 6
Ok
Lmao why is this comment look like an oblivion npc conversation
You and me both Jerald!
Bruh same
Great video. One slight clarification. The larger AWG wire for Cat 8 is not for allowing more data transmission through due to surface area. It is easier for the wire manufacturer to control the twisting of the wire pairs in a more precise way to reduce the crosstalk.
The goal on each successive option is to operate at higher frequencies and reduce more crosstalk which is beyond the scope of this discussion. That is what allows greater transmission speed.
Thanks for the explanation and feedback.
Great video, thanks a lot. I just equipped my new home with 23 Cat8 cables across the entire building, because I do not want to ever touch this installation again. So this should last for the next decades and for me the invest was worth it. Soon, the Cat8 keystones will be installed on both ends.
Awesome. That is what I call future proofing. Thanks for sharing.
@@MikeFaucher nothing personal but that is not future proofing that`s wasting money. Cat 6 is more than enough for residential and small businesses
For our new house we ran Cat6, Cat6a, Cat7, and OM3/OM4 fiber. :-)
Cat7 is sufficient enough.
@@momchil_v Can you predict the future. His house will last at least 30 years. Do you know what kinds of data speeds will be used in the year 2050?
Thank you for the feedback. I appreciate it.
I did Cat 8 because all my walls were torn out during a renovation. I figured there’s no easier time to just completely future proof my home network. Yes it was extremely expensive with the keystones and field terminations but a $2000 investment beats the hell out of having to redo it at somepoint.
I agree completely. Sounds great and thanks for sharing. Good luck with it.
$2000 ?? I bought 25 meters of cat 8 cable with 3 cat 8 connectors for each side and additional stuff for € 100.
Personally, I would do an OS2 fibre to be futureproof (>200gbe)...
Home run ENT/Smurf tube ftw. The future is whenever you feel like fishing it.
Thank you Sir!
The time spend on your videos are totally worth it.
Thank you for the feedback. I appreciate it.
A nice walk through and your conclusion is in line with what I feel atm.
For most soho installs I tend to go for Cat 6 or 6A as well.
Thanks for the feedback. Glad you like the video.
@@MikeFaucher hi sir please, if I get a linksys WiFi router + an Ethernet cable can I still connect my laptop ??
@@MikeFaucher and do I need to pay other monthly fees ?? Thanks
@@elfidel6755 Yes you can but I would use regular ethernet not this stuff.
@@MikeFaucher ok I wanna use it in my single room .. which one best can I get please ??
Seeing the pricing you've found is very interesting! Here in Canada, the pricing I can find lines up with yours for cat6 and cat6a, but cat 7 doubles it and is much closer to the price of cat8 than cat6a!
Wow, that is steep. May not be as popular or available.

Awesome thank you.
Mike great video I need you in the Bat Cave to update my equipment. You're Awesome.
Thank You. It would be fun to spend someone else money for a change.😀
Thank you for the information. I'm not building a network, but the info will aid me in building a patch cable for RF equipment between a control head and base unit.
Glad it could help.
Great informative video. Thanks.
Glad it was helpful! Thanks for the feedback.
excellent video. thanks heaps!!!
Thank you. Glad you liked it. Appreciate the feedback.
Damn today I learned there is a Cat 8.
I'm still using Cat5e and 6 at my house, which is fine.
Things sure escalate quickly
Cat5e will still be fine for a long time, as long as you don't own a palace,10G family networking can totally run in short distance with cat5e.
Same, federal ISP i'ms working for still using 5e for apartments even for gigabit ethernet
Cat 5 was the latest tech when I did Cisco networking in high school and college and 5e came out shortly after. I wired my home with cat 5 and 5e and did a few small offices where I was doing build outs as I was a pro painter and did framing, drywall, and electrical....pretty much everything for typical commercial buildings. Things change fast and I have only had to do a few patch cables in the last 10 years or so.
There are more than 8 CATS outside my place. Maybe CATS 9-15.
impressive details !
Thanks! Appreciate the feedback!
Great job ! Thanks !
Thanks for the feedback.
thanks for given practical knowledge is this very use full for me and other IT Persons very useful difference between cat 6 .cat7. and cat8....
Glad to hear that it helped and thanks for the feedback!
Perfect video. thank you :)
Awesome. Glad you liked it.
Funny how we went from thick coax cables to thin twisted pair cables and back to thick cabling again.
Just like how we have returned to vinyl records and paper grocery bags.
The good old twinax and IBM Type1 cables - how I don't miss those.
Who would have expected (back in the days of the 80's cat3-4) to be running 2GHz over twisted pair -it was generally accepted such signals were within the relm of coax.
Excellent video. Many thanks. Fully agree. 6a is the sweet spot as you can still use normal crimp RJ45 shielded termination. Cat 7 upwards just a pain! but I can see a use for datacentres.
For residential and business building to building or server to a comms I always run armoured optical pairs with 2 pairs redundant. Better performance, and more future proof than copper. Also price difference to Cat8 is negligible when all things considered.
Thanks for the feedback and the insight. It's appreciated.
2x speed is perfect! Thx for the video
Glad it helped!
Great job; Thanks!! Sparks in Daytona
Thanks for the feedback. Appreciated it.
good video , you shuld also point out that for POE cat6a and above will preform better in terms of power lost
Only for POE+, even then you could see a significant voltage drop over certain distances. Especially in use with balanced wattage applications, a larger conductor will hurt at a certain point. I think Cat6a is actually the sweet spot for this as far as carrying power is concerned.
Nice Video!
I am working as an electrician here in Austria and in my company we only install cat.7 cables and use tool-less cat.6a or 7 keystones.
If I recall correctly the bigger conductor size of cat.8 is because of the skin effect.
High frequency currents only travel on the surface of the conductor !
Sounds right as it is rated at a much higher frequency.
How is the frequency that gets used determined? Also, The cat 7 keystone is gg45 which requires an adaptor for rj45 no?
@@AlejandroTaylorEscribano The Frequency is tied to the transmission speed Higher Frequencies give you higher Bandwidth.
There are male and female , RJ45 keystones available
Female are the ones you use in special wall sockets that come empty so the keystones act as receptacles
I'm interested in seeing the cost comparison between Cat7/Cat8 and fibre.
In our network, we don't even bother with copper anymore for 10Gbit links. Costs for fibre and SFP+ adapters have really made the market competitive.
Agreed. Any time I'm looking at greater than 1G, I look to fiber, or DAC for shorter links. 10G-T is too expensive, and uses far too much power; 'tho it is getting better. Also, maybe I'm just too old... I don't see any need for 10G+ to my laptop, desktop, TV, etc.
When im doing the keystones and the final squeeze, i use a small notebook or like a pamphlet over the connector. Some thick paper and its much easier to squeeze the sucker all the way. Doesnt hurt your fingers that much either.
Great suggestion. Thanks.
Thanks!
great video thanks
Thank you for the feedback. I appreciate it.
Sounds like the best future proofing is to also run blue ‘smurf’ tube everywhere so you can eventually pull the thinner, cheaper cable that will make Cat 8 obsolete - whatever THAT is.
The only place I use Cat 8 is from my computer to my modem/router. The rest is 5e for the time being. May upgrade to 6e/7 in the future. Thanks for a very informative video for the masses.
What crazy router are you using that you see any difference between cat5e or anything else. Even regular Cat6 can pass 10Gb at short distances
Thanks for the comment.
@@kinghomer999 Not the router. I had Cat 8 on hand and used it. Plain and simple. I should not have to replace it for a long, long time...perhaps never.
It was cat5 forever. I discovered cat6 in 2015. And we're on cat8 now? Good gosh
Thank you for the feedback. I appreciate it.
Cat 7 is not recognized by TIA/EIA and thus is NOT a standard in the United States. Cat 6 was ratified the same year Cat 7 was proposed and rejected. Cat 8 however is a recognized standard by TIA/EIA.
@@scythelord yep, 7 never became an official standard AFAIK. Cat 6A was ratified in 2009 if my memory is correct, and I'm pretty sure it's a TIA/EIA standard so it's industry supported as well. Cat 6A and 8 have their place and use, but IMO they are extremely specialized and very very few people need the performance and abilities these standards offer.
@@ChristopherGoggans I have no idea why anyone would want to deal with Cat7 or Cat8. They are a total pain to deal with and fiber is better in just about every way now.
Thank you!
Glad you enjoyed it. Thanks for the feedback.
This guy is really into this reminds me of my teacher when he was showing us how to crimp these bad boys down
Thanks,
I did an install of 300 points 7 years ago. Did the same calculations and installed Cat 6. Most runs were under 30m. So still capable of 10G today. Pre terminated fibre is so cheap. So if you want to future proof install a run of fiber with cat 6 even if you don't use it. The only advantage of copper over fiber is POE. The other cool thing about fiber is you can haul a multi fibre cable and with one run have 24 or more pairs. Here in Australia it has the added benefit of almost having no installation requirements in S009. Whereas copper has seperation, weight and now power dissipation.
Thanks for the feedback.
Just imagine terminating 100's of those, RIP fingers
Yep, that would hurt.
last week did 84 of cat 6A in a little office, you get used to it.
@@anttimaki8188 I install network cabling for a living and we like to use the Panduit Mini-com jacks, no punch-down tool required, and I find they are a lot faster on terminating and entire closet.
@@NehpetsNosliw I only do these occasionally, comes with electrician Job. I use whatever the boss has bought. Havnt seen punchdowns for a while though, mostly these clipping ones. Then theres those that got a tool that punch and cut all 8 wires simultaneosly. But If you only do these like every other month its kinda hard to sell the idea to boss :)
Just a job.. here in Russia we use only Cat 5. Speeds over 1G are only reachable with fiber-optic. Cat 6-8 are not acceptable because of money/speed proportion.
I've only been retired five years and there are three new cable types. We weren't getting most requests for Cat.5E. Only a few Cat 6.
This is mostly customer generated as to cable type. Most of them have equipment they won't be replacing soon. If they were moving into a building that they're buying and doing major refurbishment I'd suggest going to the highest type emphasizing the cost of rewiring later at a higher cost. I talked a customer who was moving to wire his Unix system with unshielded twisted pair and adapters and patch panels so he could go to a PC system one day.He agreed but wasn't keen on it because his computer person said Unix would always be around.
Well, his building was struck by lightning and everything was destroyed. His computer guru said he couldn't replace it so he had to go to a Windows based network. Thats when my advice was appreciated. They just removed the UNIX system reversed the connections to the patch panels and Digi Boards and the network was running.
Wow. Thanks for the story and comment.
I would listen to this man explain how to watch paint dry. Great video!
Awesome! Thank you very much for the comment!
Well explained 👍🏻✌🏻🇨🇦
Thanks 👍
Excellent price and comprehensive comparison. My only complaint is that you didn't include the cost of any terminators/keystone connectors because I assume those are more expensive than the cable. EDIT: Yes you did
Thanks for the feedback.
Did my whole house up with that cat8 linkup cable earlier this year. Nice cable but those connectors were kind of a pain. I ended up scoring the jacket on the wires where the contacts meet them. This helped with make reliable connections more consistently.
Thanks for the feedback.
I used to run £1m rollouts of hardware including LAN and internet, we discovered that making the cables by hand was inferior to factory machine made cables, and they lasted only about 2 years before the performance started to drop off. Once we started buying custom factory made cables we got far less LAN issues.
Thanks for the feedback!
I only use field termination plugs, much better for shielding. The wires get unshielded at both ends if you use a typical RJ45, that’s were a lot of the interference will happen.
Thanks for you input!
So, I've been looking at mking my own cable at home, to save money. Looks like I'd be fine with cat 6 cable and 2 x RJ45, unless I put a wall adapter at each end; Probably a better idea.
Thanks for helpful video.
I would go with the wall plate on each end. Easier and more versatile. If you are running in wall, consider 6A for future proofing and so you can upgrade selectively to faster speeds. Just my two cents.
@@MikeFaucher Yes, I think it would be the best solution. The wifi signal gets reduced to about half. Have looked at getting extender cables for the wifi aerials that run out the back of my pc but would probably look untidy.
If you need more than 10 G you just use fiber instead. You can have 40 or 100 G with cheap QSFP(+) modules. So just use cat 6a for copper connectivity, anything better is useless because, fiber.
that's kind of what i've been thinking about. a fusion splicer is NOT needed to terminate fiber OM3/OM4 if you get a kit or the right stuff, just make sure to measure twice and cut one and i guess you could just pull it on the wall along with 6A, 5e and RG6 if you wanted the full buffet.
@@cdoublejj You look around OM3 and OM4 can be manufactured to a specific length, its not even expensive to buy, in total spent less than £1000 to fiber the whole house (9 rooms plus 2 out rooms), 10 gig to every room (40 gig to office) All the cables made to measure, a switch "borrowed" from work job done.
I agree. Distance seems to be the problem here and they have yet to fix that with copper. Fiber it is.
Well actually for big data center you want to use copper as much as possible! Copper is always faster than fiber in short runs. Cat 8 support 40 and 100 Gig-E!
Since Fibers always introduce latency and the more you have fiber the more you introduce latency, in the end, it adds up.
But agree with you if you don't have hundreds of transactional server I would go with fiber.
Each datacenter have to go through an evaluation of its needs.
@@NMETSGChan yes short runs most definitely but it seems the critical runs lately are distance and further away from the data centers. I’m shocked they are not making copper runs greater for distance.
It would be helpful if towards the beginning of the video, you specified (labeled) which cable was what color. Blue = x, Yellow = y. I spent alot of time early in the video guessing which cable was which. Great information tho. Well explained.
Great point. Thanks
Me too
So which is which?
@@dvwjr79 yellow is cat8
@@angistron thank you
@ 2:34 in the video, a lot of the CAT6a i've bought in the past 2 or so years looks nearly if not exactly identical to that CAT7, so long as it's SFTP or FSTP aka fully shielded twisted pair.
You are right as they are almost identical except for a slightly larger conductor (most of the time).
@@MikeFaucher d seem exceeding spec is not issue, at least with some 6a which i think some is even 23 gauge. but, cat 7 REQUIRES these features. 8 seems to be a true upgrade. mostly best for data center. or equipped to deal with PoE++ which can push 75 watts of power minus overhead. EDIT: also 25gbit on 6a through 8 would be interesting to see
nice video, hopefully CAT7 and 10G ethernet is gonna start to become the norm more and more but i dont see yet how anyone will need 40G in their home network anytime soon.
Thanks for the feedback.
Agreed, but ive also never met someone that could fully saturate Cat6a even in the home, aside from a rare enterprise 10g or 2g bonded connection form the ISP, and in that case even the cable is installed by the ISP from the Modem to the Router. I have full fiber gigabit internet in a large overkill network in my home nd I still run Cat5e because no single appliance/end user will be saturating a full gigabit even... And I have servers, 4k cameras etc...
@@TheRickJames you're Rick James, Bitch :D
Cat7 is not needed for 10G. It only needs Cat6 or Cat6a depending on cable length. More than 55 meters needs 6A, and the vast majority of home network installations won't even come close to that.
Im doing Cat 6a regularly these days, its cheap and easy, and will be viable for a long time. Just pains me when i come back to panel and the user is using cheapest cat5 patches they can find to connect it all :D
On my University we are still using old CAT 5 cables. Even in local PC store they have 5e and higher only, not 5 like in school :D
Damn that’s terrible 😢
and your university is called state uversity of telecommunications in Ukraine, Kyiv
lol
I´d use a pipe and go for the 6a so if in the future there is a need to upgrade this is pretty easy and you can do it where you really need it
Good idea if you can get some conduit to the location.
5:00 that is not specific to CAT8 though, you can get the exact same keystone for Cat 6 as well. It's what we have been using even since CAT6 became available. Entirely depends on the manufacturer of the keystone module.
Also I strongly advise against putting a plug on an "installation cable" (in Europe this is considered to be a botched job), these cables are meant to be terminated with a keystone module and then left alone inside your rack. Reason being the solid wires inside these cables break rather easily when bent/twisted/manipulated frequently and that leads to all sorts of "fun" connection issues.
Thanks for the input.
Do you have any examples of the advised method. A picture maybe?
Just keystones on both sides lol
With a patch panel in the rack
I think it's badass your a older guy doing this stuff keep up the good work
Awesome, thanks for the feedback.
I only have 1 ethernet cable in my home and it's a Flat Cat7 that goes from the modem to my pc (aorund 15meters). To connect my server room to my nework i have used an optic fiber cable (around 30 meters) and with it i don't have inteference problem and thick shields and thick cables.
Great. Thanks.
I'd hate to do a whole wiring job with that stuff!
I have found CAT7 to be useful when on shortish runs where interference from other sources (video, electrical...) cannot be avoided.
Haven't worked with CAT8 yet.
Both remind me of shielded token ring wiring, as it was pretty good about making it through factories with lots of high voltage equipment without loss.
Yeah it would be a lot of work.
@@MikeFaucher So was token ring! That was even better than those giant cables for S/36. Don't miss that at all. Of course we couldn't plug everything into Ethernet then, let alone wi-fi. One worker might have had a twinax for a terminal, another for a printer, token ring for a PC and a phone line and a fax line.
Thanks for the video and your effort.
It's been probably 20 years since I terminated any Cat 5 cables which were not really that hard. I'm glad I retired from the business, because I can't imagine the patience need to terminate these Cat 7 & 8 cables. Good grief. They must be 10 times as expensive as the old Cat 5 cables I used.
Cat 7 & 8 are extremely rare, it's easier (and cheaper) use fiber optics
I've installed "Cat 5e" CCA UTP cables about 8 years ago because it was cheapest. Now i'm replacing all of them with dual branded cat 6A U/FTP cable and shielded keystone modules everywhere, except for the IP cameras, those are Cat 5e FTP (Cu).
I remember arguing with someone about 2 years ago about cat 7 vs cat 8. I said "there is no cat 8, you must probably mean cat 7". I was wrong, so it seems?
Just add, don't take, your Cat5e will support VOIP, may be 7 wont?
I now have cable envy.
Man, if you are running inside of walls, use the best cables available. The labor costs of changing it later (or retrofitting it now) are way higher than the incremental cost of the cables and parts.
Very true and good point.
I wish you just use metrics system, you confusing the heck out of me.... either way, great video, didnt need that crimping tutorial but I appreciate the feedback with the difference between the cable.
Thanks
Glad you liked it and thanks for the feedback.
And here I am happily running 10gige over old cat5, hand-crimped...with no issues. =)
Mike...great video. You can't get close enough for those of us with old eyes.
Once a connector (cat 7 & 8) is terminated, can they be taken apart and reused?
And is the cat 6a cable marked as such? Is there a physical difference between cat 6a and cat 6 that is apparent when you look at each?
Are the connectors specific to each?
Thanks, I am working on better zooming for future videos that need up close work. The showed for yellow wire are reusable. Cat6a is identified on the spool and the cable itself. It is hard to tell them apart other than in most cases it is a little thicker. Connectors typically cover more than one type, but it is identified as to which it supports. Thanks for the feedback.
Hey Mike, great video. I noticed that I can get Cat6 in shielded and non shielded, but Cat6a and 7 and 8 are all shielded. I assumed as you need higher frequencies you need shielding. Do you think if I go with Cat6 I need shielding in my house? Thanks!
Interference does become an issue at the faster speed. Thanks for the feedback.
A lot of people don’t actually realise that CAT7 is NOT a TIA standard, and that CAT6a is actually a newer, recognised standard.
Very true but almost every MFG is selling and promoting Cat 7 so either one you get for the best price should be fine.
What about different Connectors like ARJ45 or TERA - I have not seen Network Switches with these sort of Connector Types so far - although I was told there are a few?
I don't think TERA will ever become popular, especially since the standard is already 17 years old and still not used.
The mian reason is compatibility.
On the other hand ARJ45 looks promising, but looking at how it works, it seems like that connector will require support from the switch on both sides to work,
and it will waste 4 wires in the cable, so I doubt it will happen.
To be hones I don't think any new standards will appear, since we are slowly getting to the point where fiber optic devices are getting affordable.
And the advantages of FO over copper are just too big.
I think copper network wires will disapear before we will get consumer available 1 Tb/s internet connections.
thnks
Thank you!
I read that Cat 7 is 1000 Hz frequency but is limited to 600 Hz if you go with a RJ45 connector.
Please see my recent comment where I list all of the frequency and connectors allowed for each category.
Well explained.
What is bets for home network ?
6A will get you to 10GbE
Informative video. Thank you so much!
If I terminate a CAT 7 cable, is it possible to attach to a CAT 8 keystone?
You should not have any issues doing that. Thanks.
Well said.- Imagine Cat 8.2 on etherchannels.
Thanks. Good video. Would your recommend Amazon’s cat 6 cables?
They should be fine. I would not hesitate.
I first use some cat 8 about 8 years ago, the termination were diabolicle
I am sure it was. Thanks for the feedback
Folks, please don’t believe everything you see on Amazon. I work on both the US and global standards development organizations that develops all of the cabling category standards and I’m going to provide a few facts about the different categories of cables and their constructions/specifications.
UTP=no shielding at all.
F/UTP=unshielded pairs with an overall foil shield.
Sc/UTP=unshielded pairs with a screened (braided) shield.
F/FTP=shielded pairs with overall foil shielded.
Sc/FTP=shielded pairs with screened shield.
Cat5e through cat6 can be constructed with any of the above depending on the users requirements.
Cat7 and up must be Sc/FTP because of the extended frequency range. The shielded pairs mitigate internal crosstalk and the screen mitigates alien crosstalk between cables in a bundle.
Cat5e=100 MHz, 1Gb/s at 100m, any connector style.
Cat6= 250MHz, 1Gb/s at 100m, 10Gb/s at 55m, any connector style.
Cat6A= 500 MHz, 10Gb/s at 100m, any connector style.
Cat7= 600 MHz, 10Gb/s at 100m, only EC7, GG45 or TERA connectors (google them), RJ45 not supported.
CatA= 1000 MHz, 10Gb/s at 100m, 25Gb/s at 50m, only EC7, GG45 or TERA connectors, RJ45 not supported.
Cat8.1= 2000MHz, 10Gb/s at 100m, 40 Gb/s at 30m, any connector style.
Cat8.2=2000 MHz, 10Gb/s at 100m, only EC7, GG45 or TERA connectors, RJ45 not supported.
Multigig/NBaseT = 2.5Gb on cat 5e or better to 100m, 5Gb on Cat 6 or better at 100m, 10Gb on cat 6A or better to 100m. Depending on cable quality you might get 5Gb on cat 5e and 10Gb on cat 6, no guarantees.
So, the “cat 7” connectors you bought on Amazon are BS because as you see from the information above, cat 7 does not support RJ45 connectors. That’s a fact. So why can cat 8 be used on RJ45 in addition to the other connectors I mentioned? It political as most Standardisation is. The US (ANSI/TIA TR 42.7 committee) never adopted cat 7 or 7A because some companies refused to move away from theRJ45 for fear that users would not support a solution that was not backward compatible. The ISO/IEC SC25/WG3 committee did ratify 7/7A components. Terminated links are called Class F and Class FA respectively.
With Cat 8 we had the same concerns in the US so two grades were created, 8.1 and 8.2. The transmission specifications are identical but it much easier to achieve with the non-RJ45 connectors.
I hope this helps and I’m happy to discuss via comments or privately if anyone has questions.
Thanks for providing the extra detail.
@@MikeFaucher No problem!
Thanks for this info noted on this!
What is cat 6e?
Cat 8 more suited for data centre application. Very informative video.
Thanks for the feedback. Appreciated it.
There is no point to it there either.
Wow! $20.00 for two Cat8 Ethernet Cable Connector! It may be beneficial to wait a few years before I upgrade my 5e at my house.
Yep, super expensive.
You will never need to upgrade to Cat8. Speeds over 10 gigabit are much better served by fiber optics. The hardware for running Cat8 at those speeds is much more expensive and power hungry than the hardware for running those speeds over fiber.
This stuff isnt for home use. It's for connecting routers to switches and other things that are moving a huge amount of data around, usually locally. Fiber is a much better option, this stuff is a unicorn.
Cat6a shielded solution, Commscope or molex is what we install. No dramas, easy passes when testing.
6a is a great choice.
running 10 gbps cat5e on a multigig switch, which is mush easier to install as of thickness and price in homes and small office
They could have added a screw-on instead of the ziptie to make it "nicer". I don't think the length would have matter anyway.
I was looking at patch cables today, and it seems that many companies are putting 26 AWG wire in their cat 6A patch cables, but using thicker wire in the cat 6 cable, which baffles me, because i often see like in your chart that you show 23 AWG wire for the 6A cabling. It seems like in patch cables, the more expensive 6a is using thinner wire!
Patch cables are mostly stranded wire and wall cables are solid.
Great
Thank you for the feedback.
So I have two cat 8 cables that are only 26AWG really weird but it works. I had to solder the leads to the Cat8 RJ45 clam shell connector since it’s so thin.
You have the multi-stranded wire which is designed for patch panels.
@@MikeFaucher ah okay, I have just have a 1 gb network rn was thinking abt building up a PFSense box with a 10 gb nic. You think I should opt for some 24 gage cat 8 or just stick with the patch
@@restrelax6282 Pfsense will not take advantage of anything over 1G. I would suggest putting 10G switches and 10G Nics for internal traffic to NAS or Media servers. For 10G you can CAT 6A or Cat 7 Patch and use 6A shielded for the in-wall stuff.
@@MikeFaucher ah okay, thanks for the help!
This is great showcase of fact, that optic transmission is the future.
Which fact do you mean? It depends on the environment. For long distances optic transmission is better suited. But for an in-house installation Ethernet is better suited. Because if you use optical transmission, you still need an active(!) media converter to RJ45 (which needs electricity). Furthermore, Ethernet provides Power over Ethernet which is super convenient for Wifi access points or cameras or an interphone system. Last but not least, fibre cabling is very sensitive and less flexible with respect to the bending radius.
@@rohrbold see Bend Insensitive fiber optic cable.
@@richardj163 Thanks for the hint, wasn't aware of that.
I think actually the future is going to be wireless only for office and home use. They can get crazy speeds over short distances on the millimeter wave band. Speeds that a copper cable will never even approach. Optics will always cost a bit more due to the fact that rare earth metals are needed so it's wireless where cost is a concern. For industrial and data center applications fiber optics is the way to go.
@@YouCanHasAccount i just bought 90ft of fiber with the proper terminations for about half the cost of just a cat 7 cable. fiber is cheap as fuck.
Nice
Thanks
I got rj11 phone line connecting my Tandy and Commodore
That's why a couple of metres of good CAT8 cable can cost you a lot. I'm sticking with my CAT5e and CAT6 for now. 😂
Im putting in cat 8 Northern Ireland is only gettting 1 gb for now but i can see it exploading in the future
Nice speeds. Good luck.
ya I am gonna stick with my cat 6a for now
As you should.
Looks more like RG coaxial cable but with more core wires.
we received new cat7 2m cables, and they are super thin and I have also seen flat cat7
Great to hear. Thanks for sharing the feedback.
Hi, great video. I am just in the process of upgrading my home network. I have cat8 running to my outhouse office (25m run from router). I had to cut the Cat8 lead to fit through the hole in the wall. To join the cable back together i couldn’t find a Cat8 lead connector anywhere online, only Cat7. Would a Cat7 extension connector limit the Cat8 speed or am i best soldering the 2 cut ends back together ?
Thanks for the feedback. It is appreciated. I would not solder. Here are a couple that I have tried with no issues, and there are many others as well. amzn.to/44id9JS, amzn.to/3JRArOz assuming you are running 10G
Cat 8, when you need to run a drop through an 'always on' 70's microwave display.
I had to run a ethernet cables on the roof of a high power radio tower building, Cat 5E UTP couldn't work well and was trying to link up at 10mbps, but Cat 5e STP (shielded) worked fine at gigabit speeds, even at high 100MHz noise level. So to me cat 8 is for very specific uses at higher speeds, and I might as well use fiber at that point.
The standard for cat 6a cable is 23 awg. I see a lot of vendors sale cat 6a cabkes in 26 and 28 awg. How will smaller gauge conductor affect performance?
Typically the smaller wire is multi-strand wire an$ is what they use for patch cables. Very hard to work with if you crimp your own but multi strand allows you to use smaller wire and get the same performance.
i guess will go for fiber for next
I remember that five to six years ago I saw technician make in-situ fibre optic patch cord in a newly constructed building's telco communication room. At that time the machine used was portable and it is far more easy to make than yours Cat-7 or Cat-8 plug and socket. What's the point of Cat-7 and Cat-8 cables then?
Fiber Optic cables are cheap, reusable for higher speeds and easy to make, but the devices are expensive.
That's why usually you will have copper when distance is low (
That machine is a lot more expensive that even very good crimpers. Still, I'd only use this kind of copper in-rack, as soon as I have to put in a conduit I'd go fiber.
20:09 well you could use a hub/repeater or an industrial brand of an rj-45 amplifier.
Good point for length.
@@MikeFaucher Only bad thing is the amplifier doesn't just amplify the signal; it also amplifies noise too :/
In a small home, a Cat6 will be just as good as a Cat7 or Cat8. Here in Norway we all just skip the Cat7 all together, and we use mostly Cat6 in all kind of buildings. Sometimes we use Cat8 in bigger businesses, but rarely. I should also add that Cat7 and Cat8 is very close in price now in late 2022, and both is almost twice the price of Cat6
You are right, cat 6 is fine for shorter runs. Thanks for the feedback
I’m reading on the product information page for bulk cat8 cable that most Ethernet ports on devices are not properly grounded. Do I need to ground the shielding somehow, or is it just overkill? Trying to search the Internet and not really getting a clear answer.
e.g. product B07JQ2GSFQ on Amazon. Down in the description it states : "Important Note
***Routers, switches and modems with proper RJ45 port grounding recommended. Unshielded devices can generate an "Antenna Effect" and can cause network bottle-necking when used with dual shielded wires.***”
Having grounded equipment or a shielding patch panel should be all that you need. You do not need a separate ground.
And here's me still using CAT5a.
Cat5E
@@fenc666 yep
@@gordonlawrence1448 I recently had to overhaul a building that was wired with CAT3!
@@DavidMBebber I cant even remember what Cat3 was. I can remember Cat1 being Coax. Then cat 5 was twisted pairs.
@@gordonlawrence1448 en.wikipedia.org/wiki/Category_3_cable
"Category 3 cable...is an unshielded twisted pair (UTP) cable used in telephone wiring...
designed to reliably carry data up to 10 Mbps."
And though the building was run using CAT5 cables each one was split 4 ways and each jack only had a single pair of wires terminated to it.
For a majority of applications, just run 6a. It hits all the needs for most businesses, small, home, and enterprise. Inside the data center is a little different.
All a typical home needs today to have Gig speed is cat 6. Devices capable of using bandwidth in excess of 100kb should have cat 6 patch cord ie. Apple TV.....
