MEMS Mini 4x4 Fiber Optical Switch

Non-Latching Type, Bidirectional, SM, PM
  • Reliable
  • Compact
  • No Drift
  • Low Loss



The MEMS 4×4 Series Fiber Optic switch redirects incoming optical signals into 4 selected output fibers.  It is a true nonblocking device that accommodates all possible light paths. This is achieved using a patented MEMS configuration and activated via an electrical control signal. It uniquely features highly reliable thermally activated micro-mirror, and no drift over time. Light path is bidirectional and nonblocking. The mini version substantially reduce the loss and increase reliability.
