Anritsu MU100020A – OTDR Module, 1310/1550 nm SMF For MT1000A Series Network Master Pro

The Anritsu MU100020A is an OTDR module for the MT1000A Series Network Master Pro, delivering single-mode fiber characterization at 1310 nm and 1550 nm wavelengths. This module performs fault location, length measurement, and loss analysis on ITU-T G.652 SMF (10/125 µm), with dynamic range of 39 dB at 1310 nm and 37.5 dB at 1550 nm. Event dead zone reaches ≤80 cm typical, while backscatter dead zone is ≤3.8 m (1310 nm) and ≤4.3 m (1550 nm) at IOR 1.500000. Distance measurement capability extends to 100 km with up to 250,001 sampling points.
