The JDS Uniphase SB04B5 is a programmable 1×4 fiber optic switch designed for optical signal routing in test, laboratory, and enterprise environments. This bidirectional switch uses expanded beam lens technology with precision stepper motor alignment to deliver consistent insertion loss and repeatability across single-mode and multimode fiber networks. Control is available via front panel interface, GPIB (IEEE 488.1), or RS232 serial protocols, enabling flexible integration into automated test systems and manual operation.
