The NanoSpeedTM Series 1×3/1×4 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 non-mechanical configurations with solid-state all-crystal designs, which eliminates the need for mechanical movement and organic materials. The device is intrinsic bidirectional and has variable coupler behavior in which light is transferred from one to another port without loss. The NS fiber optic switch is designed to meet the most demanding switching requirements of ultra-high reliability, fast response time, and continuous switching operation. This series of switches are bidirectional intrinsically.

The NS Series 1×3/1×4 switch is cascade several NS 1×4.  The device is mounted on a specially designed electronic PCB and controlled by 5V TTL input signals.  A wall plug power supply in provided.   Box mounted version is an option.

[1] Operation bandwidth is +/- 25nm approximately at 1550nm. [2] Measured without connectors. For other wavelength, please contact us. [3] Cross talk is measured at 100kHz, which may be degraded at the high repeat rate. [4] Defined at 1310nm/1550nm. For the shorter wavelength, the handling power may be reduced, please contact us for more information.
