The Anritsu MU909015C6 is a micro optical time-domain reflectometer (µOTDR) module engineered for integration into MT9090A Network Master series mainframes. This single-mode fiber test module delivers three-wavelength OTDR capability with 35 dB dynamic range, enabling precise characterization of optical fiber infrastructure across installation, maintenance, and troubleshooting workflows. The compact design supports premise, access, metro, and core network testing, including FTTx deployments with high split ratios.
