980/1550nm Polarization Maintaining Fused WDM with High Extinction Ratio and Low Insertion Loss for Fiber Sensors
Gezhi Photonics utilizes unique fusing techniques and polarization maintaining fiber to manufacture the 980/1550nm polarization maintaining fused WDM. This product features low excess loss, compact size, and high polarization extinction ratio. PM fused WDM is widely used in fiber lasers, optical sensors, and optical gyroscopes.
This product can also be configured to multiplex other wavelengths, including 980/1030 nm (for pulsed laser applications) and 1064/1550 nm (for Erbium-Ytterbium pumping). Available in low power (300mW, 500mW) and high power (20W) handling versions. These components are ideal for polarization maintaining fiber amplifiers, fiber lasers, high-speed communication systems, and instrumentation applications.
