CrystaLatch™ 1x2 Multicasting Optical Switch

  • Solid-State high speed
  • Ultra-high reliability
  • Fail-safe latching
  • Low insertion loss
  • Direct low voltage drive
  • Compact
  • Low cost



The CL Series 1×2 Multicasting fiber optic switch connects optical channels by redirecting an incoming optical signal either into a selected output fiber or splitting equally into the two output fibers. 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 solid sate CL 1×2 Multicasting 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. Electronic driver is available for this series of switches.
