The 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 WDM transponder brings you the best and simplest solution for Metro, Regional and Long Haul WDM optical networks.
