This listing includes the Viavi MTS 6000A mainframe paired with the Viavi 8136B (listed in description as 8126B) SM OTDR module, loaded with FCOMP software for automated bi-directional fibre testing. The module supports three-wavelength OTDR measurements at 1310, 1550, and 1625 nm over ranges up to 400 km, via an APC connector. The FCOMP (Fiber Complete) software enables fully automated bi-directional OTDR, insertion loss (IL), and optical return loss (ORL) measurements — note that bi-directional testing requires two compatible units.
