The Anritsu CMA 5302 is a modular Optical Time Domain Reflectometer (OTDR) with integrated chromatic dispersion measurement capability, designed for single-mode fiber characterization across extended distances. Operating at 1310 nm, 1550 nm, and 1625 nm, the CMA 5302 delivers 38 dB dynamic range with 0.001 dB loss resolution and ±0.0025% distance accuracy. The module integrates a power meter, light source, and OTDR function into a single instrument, enabling rapid fiber installation, maintenance, and fault location workflows.
