The LBTEK 50:50 single-mode fiber coupler evenly splits the optical energy transmitted through one fiber into two output fibers with a 50:50 coupling ratio. It is primarily used in various applications such as light source beam splitting and fiber interferometers. The coupler features uniform splitting, low additional loss, high return loss, and operational stability. Each LBTEK coupler undergoes rigorous testing before leaving the factory and comes with a test datasheet for customer reference.
