DK Photonics’s 980/1550nm WDM/Isolator Hybrid Combination (WIH) is a combination of a WDM Filter and a polarization insensitive optical isolator. The WIH is a low-cost model with excellent performance including low insertion loss, high isolation, high return loss, low polarization dependent loss (PDL), and low polarization mode dispersion (PMD). This product offers integrated solution to fiber amplifier application by combining more functions into a very compact package.
