980/1550nm WDM/Isolator Hybrid Combination

DK Photonics’s WDIH is a combination of a 980/1550nm Filter and a 1550nm 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.
