EXFO OTDR SETUP

My most popular video to date with over 110k view. I go over in 24 minutes how an OTDR works, how to set it up and analyze/interprete the data.
I used an EXFO FTB-1 Platform with a FTB-730 Module.

[@josephprayogo7637]

Hey. Thanks for the video, very informative. I was wondering if this EXFO OTDR is eligible to show detailed test results (Value dB, Limit dB, and Loss dB) on a fiber optic cable that below 100m in length. Looking forward to the feedback. Thanks!

[@KevinPeres]

Joseph I am glad you liked the video. Yes it has the resolution to measure a 100m fiber. I would use the shortest pulse width with at least a 15 second averaging time. With lengths that short I typically lean towards an OLTS measuring span loss and ORL. If there is a splice or connector within the 100m than an OTDR would be ideal to measure that event

[@KKYOOSUf]

👍👍👍👍👍

[@blstzus]

Hi Kevin. Thank you for this video. One question. What is the recommended launch cable length? Do I need 500m for a network of about 10km in length? Or is 30m patch cord enough? Thanks again Kevin for this video

[@KevinPeres]

You are welcome. I am glad you found value in the video. As far as the launch. Great question. It really depends on the pulse width. One way to determine is to take the Pulse width in (ns) divided by 10. Convert to meters and multiply by 2. Example: 1 μs -> 1000ns / 10 -> 100m x 2 = 200 meter -> Appropriate launch cable (multiplying the distance times 2 is to add margin for the pulse to recover you can safely go down to 1.5 times) If you use iOLM you can get away with a shorter launch. Most of the customers I work with use 100m under 20km and 1000m over 20km. If you get into ultra long haul you need to look at launch longer than 1000m.

[@blstzus]

[@KevinPeres]

I am happy you found it useful. Have a good day.

[@j.w.8663]

Very clear explanation. Thanks. So question: [at 13:47 ] if I'm doing a very long fibre (168km), should I be actually doing a few tests/fibre at DIFFERENT pulse widths just to be able to observe the near and the far splices? (I'm doing bidirectional too)? Launch cable is 1.5km.

[@KevinPeres]

Yes you should do a shirt and long shot. 169km is very long can your OTDR test that far? What is the part number ?

[@j.w.8663]

It is an FTB-1Pro with a FTB-720C-Q1-EA-EI module. Yes, I was wondering if it was capable and may need to rent/borrow a more powerful unit. Thanks for quick REPLY! . (My other OPGW spans are 77km and 124km.)

[@leversshilenge1471]

Hi Kevin. Can you please advise if I add another wavelength to make it three wavelength when I'm testing?

[@KevinPeres]

You can add three wavelengths. We have many customers who order 1310/1550/1625nm together. typically 1625 is reserved for Ultra Long Haul or folks deploying into the L band. I hope that answers your question.

[@leversshilenge1471]

@@KevinPeres thanks much appreciated

[@ezhie88]

Thanks for this video. It's really helpful. However, there is one question I have. Thus, what is the meaning of FAIL in the top right corner of the report? Is this mean that the other side of the testing cable was not connected?

[@KevinPeres]

Sorry for the slow response I am realizing that people are actually watching the videos I posted for streaming testing purposes. the top right fail is a "Global Fail" meaning there is at least one parameter that fails. You will have to refer to the event table to see exactly what failed.

[@nazrawiashewinner876]

a question, where the fiber intervenes in the 5g, would it have a plane or where the connections go, thanks

[@KevinPeres]

I am sorry Daniel I am not sure I understand what you are asking. Can you please rephrase?

[@kenav88]

Would you say a 100ns pulse with a 15sec duration should clean it up?

[@KevinPeres]

I have not watched this video in some time. Increasing pulse width will clean up a trace but at the cost of resolution

[@brithopper]

Very good teacher

[@KevinPeres]

Thank you James I am glad you found it useful.

[@bhtradinggroup5340]

I use an OTDR to locate a break. To achieve this is the best thing to do, select auto and start a test? As I don’t know the actual length of the line to initially optimise and I also don’t care at this stage. Second, how would I identify a splice on a fibre with the otdr ?

[@KevinPeres]

That is how I typically do it. Make sure you have a nice clean launch select auto and let the OTDR optimize. If you are troubleshooting set your averaging time to 30 seconds or more. The longer the averaging time the more optimized the pulse width. Once the test is done if you locate your problem you are good otherwise you can try lowering your pulse width to increase your resolution. You can balance this with adding more averaging time. The OTDR will identify the splice for you if it’s detectable. It will have some attenuation bit more reflection. Hope this all makes sense

[@bhtradinggroup5340]

@@KevinPeres amazing! Thank you :) I run for 30 seconds as I believe that is what the auto test runs at by default. What would a splice actually look like on the otdr trace? Are they highlighted by the lines in the trace? And what sort of loss would you need to have on a splice for an otdr to pick it up? That would be really useful for locating joints in a network that aren’t on any plans

[@KevinPeres]

This should say have attenuation but NO reflection. Darn auto correct. Splices have attenuation but no reflection

[@KevinPeres]

​@@bhtradinggroup5340 splices will have some attenuation, usually a loss but can be a gainer but NO reflection. Here is an old setup guide I did with a customer that walks through OTDR setup from a basic level. There is a screen shot of the event icons in there. 1drv.ms/b/s!AmWiv8u8gNCngoA3QHAb-uN2SDP5Tg?e=Y1RVSX

[@ras2271]

Can the OTDR screen be transferred to a monitor or laptop for ease of use?

[@KevinPeres]

Yes if it’s on the same network you can use VNC. If it’s on different network you can use QuickAssist or TeamViewer. Although I have not tried it you might be able to do USB3 out to HDMI. I have an adapter somewhere I will have to try it out

[@advancedfiberoptictraining5510]

EXFO's End Of Fiber Detection comes factory default set at 5.0. DUMB, that should always be set to 20. Any fault found greater than 5.0 will cause the remaining fiber under test to be greyed out. Also, NEVER EVER change the index of refraction from factory default, it is never needed. Most fiber runs, long ones, are spliced with different vendors fibers with different IOR and most people don't even know what the IOR of the fiber being tested is anyway. Learn how to use your OTDR in EXPERT, or Advanced mode, many problems with using AUTO.

[@KevinPeres]

True Advanced Mode is always preferred but straight out of the box it is unrealistic to expect every user to be an expert. If they were we would all get paid less wouldn't we? The End of Fiber Detection threshold is on all OTDR's that I know of. Auto Mode while something I do not fully rely on is something many end users do use and has some value. Keep in mind most technicians are Jack of all Trades. Also if you do Advanced Fault Isolation any bit of accuracy helps. IOR affects distance measurements. Having been a backhoe operator some 20+ years ago accuracy matters if you know the IOR of your fiber why would you not set it? If you preach advanced testing understanding and setting IOR is an advanced function. Give me a few feet of accuracy and I will take it. It could be the difference between digging in the middle of the road or in the bar ditch.
