This GPON/XGS-PON/RFoG Coexistence Element (CEx) WDM filter module is based on thin film technology and is designed to allow GPON wavelengths (1310 nm/1490 nm), XGS-PON wavelengths (1270 nm/1577 nm) and RFoG wavelengths (1550 nm/1610 nm) to coexist on a single fiber. This GPON/XGS-PON/RFoG WDM filter features low loss, excellent port-to-port isolation and unparalleled reliability. It is packaged in an industrial standard LGX module with SC/APC connectors for use in the headend.
