Description:
The VIAVI Solutions 41DWDMC Fiber Optic OTDR Module is a single‑mode OTDR option designed for the Viavi T-BERD 4000 V2 platform. It provides SM fiber OTDR capabilities with PM VFL and includes tunable DWDM functionality for the C‑band, all within the 41DWDMC configuration. This module is used to characterize and troubleshoot fiber links by sending OTDR pulses and analyzing backscattered signals, with the DWDM C‑band tunable feature supporting testing and verification of DWDM channels in that spectral region. The combination of SM OTDR, PM VFL, and tunable DWDM in a compact module makes it suitable for integrated fiber testing within the Viavi test ecosystem.
