1480/1550 nm WDM/Isolator Hybrid Combination
DK Photonics's 1480/1550 WDM/Isolator Hybrid component utilizes thin film coating technology and proprietary designed metal bonding micro optics packaging to achieve optical signal and pump power combining and back reflection signal elimination. It provides , low insertion loss, high isolation, wide pass band, low temperature sensitivity and epoxy free optical path. 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
