980/1550nm Polarization Maintaining Fused WDM for Fiber Sensor
Product Overview
Gezhi Photonics uses unique fusing technique and polarization maintaining fiber to build the 980/1550nm polarization maintaining fused WDM. It features low excess loss, small size and high polarization extinction ratio. PM fused WDM is widely used for fiber laser, optical sensors and optical gyro.
This product can also be used to multiplex other wavelengths. Including 980/1030 nm (pulsed laser applications) and 1064/1550 nm (Erbium-Ytterbium pumping). Low power (300mW, 500mW) and high power (20W) handling are available. They are ideal for polarization maintaining fiber amplifiers, fiber lasers, and high-speed communication system and instrumentation applications.
