PM Filter WDM Polarization Maintaining WDM (980/1064, 1030/1064,
980/1550, 1550/1064,1480/1550nm)
Qualfiber fusing technique and polarization-maintaining fiber 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.
