The 10G WDM transponder can be used as a transponder or as a repeater and regenerator with optical-electrical-optical (OEO) wavelength and wavelength division multiplexing technology. It can achieve wavelength conversion, optical signal amplification, and single or multiple-channel long-distance transmission of optical signals within a single fiber. The card is compatible with SFP/SFP+ optical modules and allows for multi-rate service access ranging from 1Gbps to 11.3Gbps. It is designed for maximum configuration flexibility, with pluggable modules that plug directly into the 1U FMT managed chassis, each module occupying one slot.
