The 25G WDM converter can be used as a transponder or as a repeater and regenerator. It provides a range of options for repeating optical data signals, converting them to other optical or electrical formats, or combining multiple fibers onto a single fiber. With transparent bi-directional forwarding capability between the 2 fiber media, the 25G WDM transponder can be deployed in 10G optical network or 25G optical network, which brings you the best and simplest solution for Metro, Regional and Long Haul WDM optical networks.
