The optical power will be divided by the amount of splits. The output on the screen will be confusing as the OTDR will be seeing multiple reflections. a very simple was to think of it, is like a sonar pulse. The OTDR is measuring the time it takes for the echo to return. In a splitted environment it will be "hearing": multiple echoes. If the splits are of equal distance it may look like a single fiber shot, but if not, you will likely see 2 or more reflections on the screen. The amplitude of the reflections are dependent on what type of terminations are on the ends. The number of reflections could be used to determine the number of splits you went thru. However, don't be fooled if you see too many "spikes" along the way.. If the splits are of very different lengths from each other this could introduce "ghosts" which are a false readings. These will typically be the same distance from each other, and halving in amplitude.
@@MSB1180 i want a detailed class on otdr, insertion loss,reflectance, ,optical loss, connector loss , dbm,db and milli watt, attenuator, overload of system, fusion splice, rayleigh scattering and frensel reflection ,link budget power budget, link loss, splitter loss please do a detailed video
Very nice sir
Thanks
very informative and well described -very nice
Glad you liked it!
Such an important topic
I'm a fiber optic splicer (construction)
that was nice brother, 3 top secrets
Thanks, and glad to know that it was helpful for you.
Thank you sir for your very nice explanation
Thanks, glad to know
👍👍👍❤❤❤
sir i have a question- how otdr works in splitted / branched ofc, no video available on youtube on this issue
I will try to make video on this, stay tuned bro

Let's assume the fiber break or cut at 50km. What are the plus or minus km we can find the cut ?
You need to know the number of MHs and the OFC slack inside them upto 50 KM. Subtract them from 50 KM. You will get the exact distance
Can i have a detailed class on optical fiber field ?
Sure bro, can you please ask any specific topic in the OFC filed so that i can make video in it

@@MSB1180 thanks bro
can OTDR measure a 20,30,70 and 100m length?
Yes with the latest model OTDR / iOLM you can even measure 10 M length
It will be easier to better understand if you add diagrams to support your explanation.
@lubime10 Got it, will do in the coming video
