Product description

2x2 Polarization Maintaining Fused WDM PM Filter Wavelength Division Multiplexer

GEZHI Photonics uses unique fusing technique and polarization maintaining fiber to build polarization maintaining fused WDM. It features low excess loss, small size and high polarization extinction ratio and high isolation. PM WDM is widely used for optical sensors, fiber gyro, optical amplifier. GEZHI offer 980nm to 2000nm PM FBT WDM (Polarization Mainintaining Fiber fused biconical taper wavelength division multiplexers)with high extinction ratio loss and low insertion loss.
