LBTEK polarization-maintaining fiber couplers are manufactured using panda-type polarization-maintaining fibers, capable of maintaining a high polarization extinction ratio when light is coupled along the slow axis of the fiber. Suitable for various polarization-maintaining optical systems, they distribute input light in a 50:50 ratio to the two output ports. The couplers feature uniform splitting, low additional loss, as well as high return loss and operational stability. Each LBTEK polarization-maintaining coupler undergoes rigorous testing before leaving the factory and comes with a test datasheet for customer reference.
