1x2(2x2) PM Filter Coupler

The polarization maintaining (PM) coupler provides optical signal splitting with accurate tap ratio while preserving the state of polarization. By combine thin film filter technology and PM collimators, the PM coupler features low insertion loss, high return loss, high extinction ratio and environmental stable.

*Above specifications are for devices without the connectors.

*For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB lower. *The PM fiber and the connector key are aligned to the slow axis. And for F type, fast axis is blocked.
