From one hillbilly to another. Good job. Ive not had to do OTDR yet because i mostly do cell tower work and they usually only require insertion loss tests with an OPM but im trying to learn more about fiber optics to help with my job and any future work. Thanks for the simple demonstration.
@@user-lf7en6rf8m pon definitely adds challenges in testing. We we're mainly an active Ethernet provider for the past 20 years and now we do xgspon. If you test downstream some OTDRs say they will map splitters and what not and they have some that you can put in line between your ont and gpon card. Onts arent supposed to send light at all toward the splitter until they receive it from the head end to prevent jamming the other onts since their in time division. Really neat but definitely adds challenges Use to we could turn the switch point off on a AE fiber to test. And now we can't without cutting down 31 other customers. Guess that's where the in line tester comes in.
No sir you dont, it just shoots light waves down the fiber and they bounce back due to reflectance and the otdr reads those bounce backs to determine the events (splices, connections, end of fiber, etc). Here a link from viavi: www.viavisolutions.com/en-us/working-principle-and-characteristics-otdrs#:~:text=The%20laser%20emits%20a%20pulse,photo%20detector%20in%20the%20OTDR.
All though, in some testing scenarios a company may require both a launch and receive reel. I will try to do a quick video to explain the application of those as best I can.

Yes sir happy too! I've always wanted to climb one of those.
Thanks Dev, I don’t get to do a lot of testing with PON, however I am definitely wanting to practice and know my OTDR etc

Hello dear follower with you from Iraq, I need details of the measurement in OTDR viavi in a better way. Can I have that?❤
So you don't have to connect anything on the other side of the run?

@@hillbillynetworks8605 cool, thanks.

Is the fiber actually 7000 feet long?
The jumper you see in the pic is about 3 meters so you can subtract that out. But other than that, yes.
So, the 7000 feet of fiber are behind or after the patch panel?@@hillbillynetworks8605
great fiber with only .44db loss (:
Yep!
Hello sir
Hey
himesh vlog chanal.omi good
Thanks for watching!
