Abstract
The present disclosure provides high-speed wavelength division multiplexing (WDM) transponders (e.g., 10 Gb/s, 40 Gb/s, 100 Gb/s, and beyond) that receive one or more optical signals and convert and/or remodulate the received optical signals onto a newly generated optical channel along with overhead processing/addition, forward error correction, and the like. In general, the transponders of the present invention include a client-side and a line-side, each with bi-directional optical transmission. The transponders provide an effective mechanism to support WDM networks that are transparent to the client-side.
