The JDSU E4146QUAD is a high-performance Quad (Multimode and Single-mode) Optical Time Domain Reflectometer (OTDR) module designed for the modular T-BERD/MTS-4000 platform. Operating at 850/1300/1310/1550 nm wavelengths, it provides an all-in-one fiber optic certification and diagnostic tool for both local enterprise (MM) and metro/telecom (SM) networks. It combines a highly accurate OTDR engine with an integrated continuous wave light source and power meter, and supports advanced automated analysis features like macrobend detection.
