1X3 Polarization Maintaining Coupler

: LightComm uses unique fusing technique and polarization maintaining fiber to build the 1x3 polarization maintaining fused coupler (1x3PMC).The coupling ratio could be selected according to customer’s request. It features low excess loss, small size and high polarization extinction ratio. PMC is widely used for optical sensors and optical gyro, optical amplifier.
