PM Isolator WDM Polarization-Maintaining Fiber Isolator+ WDM Hybrid Device (PMIWDM)


Qualfiber fusing technique and polarization-maintaining with fiber Isolator to build the polarization-maintaining fused WDM (PMWDM).The wavelength could be selected according to customer’s request. It features low excess loss, small size, high polarization extinction ratio, and high isolation. PMWDM is widely used for optical sensors, fiber gyro, optical amplifier.




High Extinction Ratio and Isolation Low Insertion Loss

High Stability and Reliability

* 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.
