Optical Circulator

The polarization independent optical circulator is a 3-port non-reciprocal device that allows the light to travel in only one direction. 

Lightwave is transmitted from port 1 to port 2 with minimal loss, and from port 2 to port 3 with minimal loss. However, light transmission is blocked from port 2 to port 1, and blocked from port 3 to port 1 or port 2.


Based on the nonreciprocal polarization rotation of the Faraday effect

 Single mode, 3 ports, polarization insensitive, uni-directional operation

 Available with wavelength 1310/1550/1590nm, bare fiber, connector or unterminated

 Telcordia GR-1209-CORE and RoHS compliant

 Perfect solution for add-drop multiplexers, erbium-doped fiber amplifiers (EDFA), dispersion compensation, bi-directional communication, fiber optic sensors, OTDR and OCT applications
