2×1 Fiber Optical Switches


The Brimrose 3-port fiber optical switch system plays a major role in modern fiber optic telecommunication and sensing systems that demands high-reliability operation, response, and continuous high frequency switching.

The fiber optical switch is a powerful tool to switch an optical signal at nanosecond speed (200ns). The optical switch has two configurations: 1×2 or 2×1. The switch is bi-directional.

The optical switch consists of the all fiber optic switch device and corresponding driver packaged in a rack-mountable enclosure. The switching is done by an external TTL compatible low voltage signal.
