PM Coupler

Polarization Maintaining Fused Coupler

 

DK Photonics uses unique fusing technique and polarization maintaining fiber to build the polarization maintaining fused coupler (PMC).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.

* If tap port coupling ratio is 5%, ER will be 2dB lower; for 1% tap port, ER is out of concern

*Above specifications are for device without connector.

*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 fast axis is blocked.
