The LB Series 1xN Single mode Broad Wavelength Fiberoptic Switch connects optical channels by redirecting an incoming optical signal into a selected output fiber. This is achieved by using a patent pending opto-mechanical configuration activated via an electrical control signal. Latching operation preserves the selected optical path after the drive signal has been removed. Photonwares unique design offers low insertion loss covering a very broad spectral band from 400 to 2000 nm with various fiber core size from 5 to 100 um. The LB series 1xN optical fiber switch is suitable for multiple channel signal monitoring and signal management. The switch is bidirectional. The switch is ideal for sensor and spectroscopy applications as well.

The driving circuit is connected to computer through RS232, or USB interface for operation. The LB series 1xN optical fiber switch is compliant with the Telcordia 1209 and 1221 reliability standards.
