1310nm Polarization Maintaining Tap Isolator hybrid
1310nm Polarization Maintaining Tap Isolator
Hybrid Tap Coupler/Isolator device is a combination of a PM tap coupler and an isolator in a compact package. This product featured low insertion loss, a very stable tap-coupling ratio, high isolation, and high return loss. It offers integrated solution to EDFA application by combining more functions into a very compact package. All products are Telcordia GR-1221/1209-CORE qualified, and RoHS compliant.
