1×2 Dual Stage High Speed High Extinction Fiber Optical Switch – NanoSpeed™

50dB Extinction, 60ns rise/fall, 500kHz, 1dB loss, bidirectional, 850nm to 1620nm, -20to 80 °C
  • Solid-State
  • High speed
  • Ultra-high reliability
  • Low insertion loss
  • Compact



The NS Series dual-stage 1×2 solid-state fiber optic switch connects optical channels by redirecting an incoming optical signal into a selected output optical fiber. This is achieved using patent pending non-mechanical configurations with solid-state all-crystal designs, which eliminates the need for mechanical movement and organic materials. The dual-stage series of NS fiber-optic switch is designed to meet the demand of high cross-talk in addition of ultra-high reliability, fast response time, and continuous switching operation. The device is bidirectional.

Photonwares’ PCB driver listed in the web is recommended to operate this device, featuring high efficiency and low cost with 12V DC power and TTL control signal.
