CrystaLatch™ 1×2 Single Stage PM High Power Bidirectional Optical Switch

  • High Speed
  • Low Insertion Loss
  • Low Cost
  • High Reliability
  • Fail-Safe Latching
  • Compact & Rugged
  • Direct Low Voltage Drive



The CL Series High Power 1×1,1×2 solid-state 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. Latching operation preserves the selected optical path after the drive signal has been removed. The all High Power fiberoptic 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.
