Virtual Tour of Openreach's FTTP Network

- čas přidán 4. 06. 2021
- This video shows the inside workings of the Openreach (BT) fibre-to-the-premises network from exchange to premises. It offers a useful enginner's eye view of the network, cutting out the streetside cosmetics.
The video shows you everything from the exchange (headend / ODF) to aggregation nodes, splitters, Connectorised Block Terminals (CBT) and then all the way to in-home Optical Network Terminal (ONT / ONU). Overall, it’s significantly more informative than most of the videos out there and well worth a watch if you want to understand how FTTP works on Openreach’s platform.
I'm glad youtube chose to show me this video. Right up my street - very interesting.
My goodness, I remember working in and around Bradford, most of the telephone exchanges. Back in the good old days of Newbridge Networks ATM, and Marconi SDH.
Interesting video, it's right up there with my interest, electronic, I would definitely be up to getting the training to become a BT Openreach engineer likely 2022 some point.
Same here mate, best of luck to you!
@@samconroyy Here's wishing the best of luck for us both.
You both sound like you have too much ambition and interest to be an openreach engineer. I'm sure they will beat this out of you within a couple of months. I certainly get this impression from the engineers I talk to on a daily basis.
It's passion for technology, and why not make a living on the side from something you love doing or have interest in? I don't see a problem, life's hard, from the moment you're born it's a uphill struggle from getting good grades to landing a good paying job, show me somewhere where life isn't hard.
@@andicalman4975 if you have a passion for technology then becoming an openreach engineer will kill that passion. I've been involved in dsl and ethernet support for a decade. The people you speak to at openreach don't know how their technology works. I speak to engineers who don't know what an snr margin is but then proceed to tell me why they disagree with me about where a fault lies. I speak to the ethernet guys, tell them we aren't seeing light from their interface and they say 'Of course. Your port is faulty so that's why we aren't sending any light'.
Dealing with openreach is like trying to walk through treacle. I'm not gonna name any names but there are plenty of other companies rolling out full fibre that I would consider over openreach. They are good because they need to be because are competing with openreach, who essentially inherited a monopoly.
Can anyone advise?
Just had my overhead fibre installed. They ran it down the side of my house but just tacked it on to the existing copper wire with cable ties, rather than pinning the wire into the wall neatly as per this video. It's an absolute mess with loose wires and slack everywhere. Do I have any grounds to contact openreach to rectify this installation to what I assume is openreach min standards?
8:48 yes and one of them is mine :) and it's been prefect so far
Also what is the round Orange sticker on CBT what does that mean for the CBT?
I notice that in more recent installations the ONT is not provided with a battery backup. Ours is an earlier one that does have a battery backup using 4 rechargeable AAs in a separate unit that sits within a larger case with the ONT itself.
It makes me wonder about older people who have always relied on the landline during power cuts. I assume the battery backup is still an option if requested?
Not legally required anymore so they don't provide it to save cash
We never put the fix on the fascia after upvc was introduced, always into brick!😉
Open reach needs to stepup to complete with City Fibre because City Fibre will offer equal upload and download speeds including battery backup for both router and digital voice calls because older people will not have Internet but want a phone to call people and have safety alarms to call health services for help.
city fibre is an absolute mess mate, using unproven sub contract fibre engineers that have no clue what theyre doing in many cases.

Mmm presume u work for the legendary BT !
See numerous comments below about the standard of BT workmanship !
@@lukather1 No i work self employed for multiple ISP's. There's a reason most of these companies like CityFibre are merging, folding or filing. Think CityFibre have reported around £500m in losses over the last 4 years. BT are using cheap labour to do home installs and connections at the cabs, the actual network itself is quite tidy and well maintained.
NGE had the best network structure, dropped their own boxes, ducting and poles but i think they've now pulled out due to project costs.
s it intended for FTTP to replace FTTC completely? Many residential premises are fed by cables buried direct in the ground with no duct employed. This certainly was the usual method when I worked in Local Line Planning (pre-BT days!). If not, is FTTC being developed in order to reduce the length of copper cable pairs between cabinet and customer? We are about a mile from the cabinet which limits our download and upload speeds. FTTP is being installed in adjacent streets served by overhead distribution.
UK should have been on FTTP 20 years ago. This is all one big game of catch up thanks to years of useless tory governments that put network infrastructure on the backburner.
Ex openreach employee also worked for BT for a while. Good memories.
The most important part of the ODF installation is the phucking labelling
Yes and I always known it as a field for obvious reasons, and it always goes hand in hand with job security lol Like 6G, there will not be any towers to put labels on lol And thank you for that constructive comment, its pleasing to see you depth of your dictionary.
@@stephenjones2867 What does 6G and antennas have to do with ODFs? Those that have worked enough fibre faults will know exactly what my comment is about
what is this building? Exchange for the whole city which is directly connected to the internet backbone or local exchange for an area which connects to the city exchange before connecting to the broader internet?
It's the openreach training centre in Bradford.
@@colinbaird33 oh. but what it's trying to replicate? the whole city's exchange?
@@k7y its a mock up of the whole fttp network. Its not actually an exchange, its just showing what parts of the network look like as you go along, the house at the end isn't a real house. Hope this helps.
Bear in mind that I am not in the industry, so this answer may be a little wide of the mark in one way or another. However, I will answer to the best of my knowledge.
My understanding is that, in the BT/Openreach network, there isn't really a hierarchy of exchanges in the way you envisage. The exchanges are all largely equivalent to one another, in terms of the logical role they play in the network. So, I would think it doesn't really matter which exchange is represented in the training centre.
The Internet Backbone does not connect directly to Openreach exchanges. Instead, it connects together "internet exchanges" around the world, including the handful that are located in the UK.
ISPs and other operators of large networks use internet exchanges as a place to connect their networks to one another and to the internet backbone. Typically, each ISP has its own separate "core network". Large internet services and CDNs often bypass the backbone entirely, connecting directly to ISPs' networks.
On the other side of things, the ISPs make connections between their core networks and the Openreach infrastructure at various points. A handful of ISPs take their networks all the way into each local exchange (or further) and then they compete with Openreach itself to provide connectivity for other ISPs into Openreach's local infrastructure. (At least, this is how it works for ADSL and to some extent VDSL. I presume similar arrangements are being made for FTTP.)
As I say, I'm not in the industry, so take it with a pinch of salt, but hopefully I'm not too far off.
Would love to get excited about this but as I live in an area with crap broadband, I won't. Plenty of fibre hanging from poles in this part of Wales but not much going into houses!
Yes, just filled out a Barclays Customer Survey. I used to use Barclays number back in the 90s for internet connectivity. Used to do searches for a female partner to spend my hard earned salary on, But the search results kept on bringing up the Philippines and their antics. I wonder what my manager had to with those results to end up me having to socialise with him. Thank you Ericsson for noticing...
Phone openreach.
Can’t wait till you put it in my address later this year
20:00', well, if you think about it, they do say that: "Customer is always right".
I was promised this in late 2018. cables run to the connection box and now Sept 2021 still no connection. Openreach are saying there is no connections. Engineers who look at the pole say it is connected just needs running to the house. Not happy.
I'm in the same boat my whole area is done but they missed putting my house on their stupid database as fiber ready. Openreach won't do anything and the service provider won't raise anything up.
Its a joke because our tax is paying for this shit. Even my Council is not having much luck with openreach and their paying the bill which just had one for 3 million quid.
BT is a waste of space.
Well
interesting
Good video. Problem is that more laptop computers are now being built with no Ethernet ports, so WiFi is the only option.
Use a USB ethernet adaptor.
Premises are land and buildings together considered as a property. ... Note that a single house or a single other piece of property is "premises", not a "premise", although the word "premises" is plural in form; e.g. "The equipment is on the customer's premises", never "The equipment is on the customer's premise".
premise...premises.... remember he's speaking Yorkshire
ffs
INteresting... what is stopping a malicious actor from shining a laser back up the fibre and ruining the service for everyone sharing the same splitter? also what colours / frequencies are used please?
Can someone please explain why Fibre to Premises is asymmetric? I have friends in Germany with symmetric connections!
Most Fiber to the home deployments here in the US use a technology called PON or passive optical network. This technology allows multiple customers to share the same strand of fiber back to the head end. There are different speeds of PON... GPON or gigabit PON is the most common as of now and can move 2.5gbps download and 1gbps upload per strand of fiber. With this asymmetric capacity, most providers sell asymmetric connections.
Because ISPs believe you'd rather have more download speed than upload speed, and unless you're a business that needs high upload speeds, that line of thinking is generally correct.
@@lukesymmons yes but with technology moving to cloud based services then upload speeds become important in a domestic setting
@@crizzo8846 if you're talking about VoIP devices, they don't need that much upstream bandwidth to work.
I was referring to cloud based storage services
Do the Agg nodes feed Alt nets also who don't have their own exchanges?
is FTTP something new in the UK?
Yeah pretty new. I think it's something like 25-30% of houses (me included fortunately). We do have Virgin Media though, who for the vast majority of connections province cable services over their own network, fibre to the cabinet and then coaxial for the last stretch. I preciously has their gigabit package. Most other connections are FTTC via Openreach.
@@dreammclackers I think FTTP is up to 33% in the UK now which is cool. I expect there will still be many places on ADSL for many years to come though.
@@lukesymmons Apparently my area will be stuck with ADSL until 2026. The pain continues.
@@portman8909 There is always FTTP On Demand if you're that desperate and willing to all come together (only problem being there is a bill to pay for the works)
lol they were just getting into mass fusion splicing 3 years ago
Very interesting. Thanks for making it available to a wider audience. I have FTTC with 37 down and 8 up but I was quite happy with my previous 8 down! - I do not stream and zoom was fine. What I need is fast up for cloud backup - it was taking 12 hours to upload 5GB key data. Now it is still 2 hours. I get the impression that for basic users FTTP will be only 10 up unless they pay for more down speed than they need. Can individual customers opt for at least synchronous speeds (say 20 up & down)?
Why not have a charge per GB like mobile networks? That would make people better utilise the network bandwidth - no more downloading a film to only watch 10 minutes and deciding they don't like it! And what about the environmental impact of 20M ONTs on 24/7 plus the fire risks when using these plug in PSUs.
Also, I have 8 IP addresses. Will FTTP with the ONTs allow this? Will the BT digital voice line have it's own IP address (say 1 of my 8) so I could route it straight into my Asterisk server (a Raspberry Pi)? Currently I have a analogue to digital/IP adapter. Thanks. Alan
I am with by got fttp and they can't get 150 mb been a week of complainting
our local phone company has this adage: LEFT out side... RIGHT in side.
i`m in phase2 whenever that is :(
We got full fiber today yay
HAHAHA LC 'little connector' I suppose it helps you remember lol
and on the node
"Light on the LEFT and Customer is Always (on the) RIGHT"
What a lad.
Lucent Connector
Ha!..OpenReach, I have had 3 visits from their engineers recently over speed problems with FTTC connection, the result being no improvement so i gave up! I even had to tell the last engineer, that the modem cable is RJ11 and the ethernet cable is RJ45.....he said he could not remember?
BT can't even get the lip sync correct
Blame teams, we can only do so much lol (my opinion not my company)
went to sleep watching this lol
what bugs me about this, is that they are going for the worst way to distribute fttp, instead of having a passive cable from house to exchange each they are using a branch method to save money but these will struggle if everyone wants to connect to them, look at all the rack space used for that town, its nothing they have these building in all the towns and they could easily use a ring network and passive cable to each premises which will allow future speed upgrades easily, what they are building here is no good if everyone in a town went for the 900mb package
They are eventually getting rid of most exchanges.
why 900mb costs a chunk more as most ae cheap asses
They're betting on most people not going for the full 900mb speeds, and they're probably right. A lot of people don't really understand the difference in internet speeds, but they do understand the difference in the monthly fee's! If the lower speed would suffice to their needs, and save them ~£20 a month, they're gonna pick the lower speed. Media streaming (like Netflix) is pretty dominant now over downloading media, and you don't exactly need 900mb for that
That's BT for you, they only think about the now and not the future, community fibre is offering 1 gigabit service and soon 3 gigabit, Virgin media were testing 10 gigabit at some area of the UK. Why must BT always cut corners? Shameful and a wasted effort.
Having dealt with BT/Openreach in all its incarnations over 30 years I'd expect nothing less than corner cutting wherever possible.
Should be wearing safety glasses.
Yes, and I yet to see ESD shoes being used. Even though 'we' were conditioned to use ESD footwear way back in (for me 1994). I don't like making it obvious but I even had to go out and by ESD steel toe capped boots which had ESD blazened on the side of the trainer. One place I worked and went back 'by accident', suddenly a manager started to where white sold shoes in the data centre like I did. I always look at shoes, something I picked up with something someone said to me once.... Don't know about you but I am tired of people not showing me what is the minimum....
@@stephenjones2867 Curious why you think you need ESD shoes to deal with fibre optics. It's glass and light. No electrical signal to be seen anywhere...
@@stephenjones2867 You would think these things would be provided to the janitor.
@@trollobite1629 Yes, what was I doing in a data centre and in another role wearing safety boots with a degree and a PGD? My manager was in the wrong industry and I see he is in the right one now, Lets hope people clean those glasses more often.....
@@stephenjones2867 You don't need nor are you required to wear *"..ESD safety footwear..."* in a data center, headend or at ODF panels. The places required to wear ESD shoes is exposure to electronic components in packaging, or service departments working on electronics EG PCBs. The reason for that is clothing can easily generate in excess of 10 thousand volts which is more than enough to damage your circuit boards.
WTF is a "premis" do you mean a "premesis" ... "premis" is American and last time I checked we weren't in the USA!
John 3:16-21
16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
always one
