LD-PD's Polarization Maintaining FBT or Filter Coupler PMTC Series Products, are used to divide input polarization maintaining fiber into two outputs according to the established spectral ratio. It is widely used in the fields of fiber laser, fiber amplifier, fiber communication and fiber sensing, with compact configuration, low insertion loss, low polarization related loss and high stability.

*Above specifications are for devices without the connectors.

*For devices with connectors, IL will be 0.5dB higher, RL will be 5dB lower, ER will be 2dB lower and optical power is only 1000mW (CW). *The PM fiber and the connector key are aligned to the slow axis. And for F type, fast axis is blocked.

*The material must be RoHS compliant
