Designed and produced by MEISU, this mini PM fiber coupler can split the input power stably in the splitting ratio of 5:95. And similar to the other PM coupler produced by MEISU, Mini PM Coupler (5:95) can also maintain the beam polarization during the use. Moreover, designed with multiple available channels, including 1× 2 and 2×2, this polarization maintaining coupler also comes with a compact packing case, which is specifically suitable for Fiber optic gyro (FOG).

How pm fiber coupler Works

MEISU mini PM coupler 90:05 is similar with 1x2 PM fiber splitter. It is fabricated with waveguide chip, single channel polarization-maintaining fiber array as the input end and a 2 channel polarization maintaining optical fiber as output ports. However, different from regular fiber optic plc splitter that split the input power evenly, it will split the input power in the ratio of 95:5.
