How To: Avoid Common OTDR Test Problems

An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an #opticalfiber. Ensuring the reliability and quality of an #OTDR is crucial. Watch the video to learn how to test an OTDR and avoid some of the common problems. #HowTo

Really appreciate for this kind of stuff. Please produce more videos like this on other equipment and tools

morw videos pls about otdr thank u for sharing

[@MSB1180]

Thanks, I have one question why OTDR often misses some splices of the fiber under test

[@DKy0]

Pulse width is too big. If your pulse is at 30ns then your pulse will be 3 metres long, any events in that area will be shown as just one event and not individual events.

[@BekoIQ]

You should check the threshold setting maybe the values very big and your events less from theses values so will not appear in table

use a fiber inspection. usb van be interface to the otdr.

[@kingsman428]

A clean step with no spike is much more likely to be terminated with an APC connector that has a very low reflectance around neg 60 whilst a peak is indicative of a broken fibre with a very high reflectance level

Some things wrong in the video How to plug APC connector to UPC coupler

[@trollobite1629]

It shouldn't make any difference the housings are identical it's the end faces that are different

[@trollobite1629]

Ha just noticed you got it wrong too. It's a UPC connector plugged into an APC coupler 🤣 However, it still doesn't matter 😁

[@moatazasadek]

It will cause high loss than the normal, And in our field it is fital mistake but for you no worries do what ever you want :)

[@trollobite1629]

@@moatazasadek No it won't. You will get a high loss if you try to interface an APC connector with a UPC connector but that's not happening. He's interfacing a UPC fibre to a UPC fibre. The housing makes no difference. If you don't believe me join 2 APC launch leads together using both types of housing and shoot light with your OTDR and no significant loses will be observed then join a UPC and An APC launch lead together and shoot light from your OTDR and you will see loses no matter which housing you use. The only difference between the housings is the colour, all the alignment is done with the fibre face angle.

[@moatazasadek]

Ok no problem you look understood the field good and i trust your. Thank you for sharing,

Expo ka order tres 2013

[@wojciechs5044]

Too short launch cable even for exfo 720, OTDR has no chance to correctly measure the parameters of the first connector and the fiber after it, giving a low-accuracy measurement as seen on the screen. This measurement does not reflect the true characteristics of the fiber under test thus not reliable.

[@hemantsurti6021]

Ok
