Newport PTS-FOSW 1×4 Fiber Optic Switch Module (1×4)

The Newport PTS-FOSW 1×4 Fiber Optic Switch Module routes optical signals from one input port to any of four output ports, with reversible 4×1 operation. This optically passive, bi-directional module is transparent to bit rates and data formats, making it ideal for automated fiber alignment, passive component testing, multi-port device characterization, and fiber optic sensor systems. A single light source and optical meter can test multiple devices or selectively bypass components. PC-controlled remote switching enables automated test sequences, long-term burn-in, and environmental testing.
