Neptec Optical Solutions PM Fused WDM Coupler uses a unique fused technique and polarization maintaining fiber to build the polarization maintaining fused WDM (PMWDM). The wavelength can be selected according to customer's request. It futures low excess loss, small size, high polarization extinction ratio and high isolation. PMWDM is widly used for optical sensors, fiber gyros, optical amplifiers.
