Eight-Channel WDM Fiber-Optic Data-Communication System

A proposed wavelength-division-multiplexing (WDM) optical communication system would feature a single optical fiber carrying eight channels of digital data signals. In the original application, the signal in each channel would be a serial digital video-camera output, but the system could just as well be used to convey other serial data streams. The data rate in each channel could be as high as 2.5 Gb/s.
