DK Photonics' 1940/1570nm WDM/Tap Coupler Hybrid Combination is a combination of a wavelength division multiplexer, a tap coupler 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 amplifier application by combining more functions into a very compact package.
