CrystaLatch™ 4x4 Optical Switch

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



The CrystaLatchTM (CL) type 4×4 fiber optic switch connects optical channels by redirecting any incoming optical signal into any selected output fiber. This is achieved using patented non-mechanical configurations and activated via an electrical control signal. It is a truly non-blocking switching matrix. Latching operation preserves the selected optical path after the drive signal has been removed. The all solid state CL 4×4 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.
