980/1550 nm WDM/Isolator Hybrid Combination
DK Photonics's WDIH is a combination of a 980/1550 nm Filter and a 1550 nm polarization insensitive optical isolator. The WDIH 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 EDFA application by combining more functions into a very compact package.
The products are Telcordia GR-1221/1209-CORE qualified, and RoHS compliant.
