The CL 1×2 3-Stage Series fiber optical switch connects optical channels by redirecting an incoming optical signal into a selected output fiber. This is achieved using patented non-mechanical configurations and activated via an electrical control signal. The latching operation preserves the selected optical path after the drive signal has been removed. The all solid sate CL 1×2 3-stage fiber optic switch features low insertion loss, high extinction ratio, high channel isolation, and extremely high reliability and repeatability. It is designed to meet the most demanding switching requirements of continuous operation without failure, longevity, operation under shock/vibration environment and large temperature variations, and fast response time.
The switch also has build-in circulator and isolator functions. An electronic driver is available for this series of switches.
The magneto-optical crystals used in the CL switches have no fatigue or drift effect.
