The JDSU SB08BS-C2SU is a single-mode fiber optic switch offering 1-to-8 optical routing in a C-configuration architecture. This bidirectional device employs expanded beam lens technology with precision stepper motor control to deliver low insertion loss and high repeatability across a broad wavelength spectrum. Manual front-panel operation and remote GPIB/RS-232 control enable both standalone and automated test environments.
