The LBTEK polarization-maintaining fiber coupler is manufactured using panda-type polarization-maintaining fiber, capable of maintaining a high polarization extinction ratio when light is coupled along the slow axis of the fiber. It is suitable for various polarization-maintaining optical systems to distribute input light in a 1:99 ratio to the two output ends. The coupler features uniform beam 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.
