  • PM and Non-PM Pump and Signal Combiners (2+1)x1 for CATV and Telecom Applications

    High power 1550 nm amplifiers based on double clad Er/Yb fibers are widely used in CATV and Telecom applications. TF's (2+1)x1 Pump Combiners can be used to combine the power from two multimode laser diodes and signal channel into one output fiber, delivering the combined power with pump signal for applications in industrial, military, medical and telecommunications markets. The configurations can be fully customized based upon request.
