980/1550nm 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 independent. This product has an extremely low insertion loss, high isolation, and high return loss. This product offers integrated solution to EDFA application by combining more functions into a very compact package.
