What is OTDR test for Fibre optic cable?

The Optical Time Domain Reflectometer (OTDR) is useful for testing the integrity of fiber optic cables. It can verify splice loss, measure length and find faults. The OTDR is also commonly used to create a “picture” of fiber optic cable when it is newly installed.

How should you connect the OTDR to the fiber optic cable?

Test Procedure

1. Turn on OTDR and allow time to warm-up.
2. Clean all connectors and mating adapters.
3. Attach launch cable to OTDR. Attach receive cable (if used) to far end of cable.
4. Set up test parameters on OTDR.
5. Attach cable to test to end of launch cable. Attach receive cable (if used) to far end of cable.
6. Acquire trace.

Can you OTDR multimode fiber?

Some multimode OTDRs are now usable for short length multimode premises cables but only if they are properly set up before use. The launch cable also allows the OTDR to check the first connector on the fiber being tested. An OTDR must always be used with a launch cable that matches the fibers being tested.

What kind of company is Viavi solutions?

Viavi Solutions (stylized VIAVI Solutions), formerly part of JDS Uniphase (JDSU), is an American network test, measurement and assurance technology company based in Scottsdale, Arizona. The company manufactures testing and monitoring equipment for networks.

How do you read OTDR results?

How to Read Your Trace. OTDR displays will show a Y and X axis. The X axis measures distance, and the Y axis measures attenuation and reflection in dB. Before running your trace, select the appropriate fiber network length, pulse width and acquisition time.

How do I set OTDR parameters?

To select Manual OTDR mode, turn the rotary switch to AUTOTEST, press F3 Change Test; then select Manual. You can access these settings on the Fiber OTDR tabs in Setup. Tip: To see the settings used for an OTDR test, press F2 View Events on the OTDR Results screen, press F3 View Details; then press F1 OTDR Settings.

What is the difference between a TDR and an OTDR?

Essentially an optical time domain reflectometer, OTDR is the equivalent of an electronic TDR, but for optical fibres. It then receives and analyses the light that is scattered by Rayleigh backscatter or reflected back from points along the fibre.

Which wavelength is recommended for OTDR testing?

Generally speaking, 1625 nm is the preferred wavelength for monitoring legacy 1310/1550-nm systems, largely due to laser cost. The 1650-nm wavelength is recommended for CWDM, DWDM, XGS-PON, and TWDM-PON systems where the traffic wavelengths extend into the L-Band.
