The Anritsu MU909015B1 is a µOTDR module engineered for the MT9090A Network Master series mainframes. It delivers dual-wavelength operation at 1310 nm and 1550 nm, a 35 dB class dynamic range, and an integrated Visual Fault Locator for field fiber certification and troubleshooting. The module supports single-mode fiber testing with real-time sweep capability and automatic parameter selection, making it suitable for both installation and maintenance in FTTx and PON networks.
