DK Photonics' 1940/1570 nm Polarization Maintaining WDM/Isolator Hybrid Combination is a combination of a wavelength division multiplexer and an isolator in a compact package. All input and output fibers are polarization maintaining. This product has an extremely low insertion loss, a very stable tap-coupling ratio, high isolation, and high return loss. This product offers integrated solution to fiber laser application by combining more functions into a very compact package.
