DISTRIBUTED WAVE DIVISION MULTIPLEXING SYSTEMS

摘要

A distributed wave division multiplexing system includes a first multiplexing device and multiple second multiplexing devices. The first multiplexing device separates Y number of subscriber signals carried over an input line onto X number of channel lines by wavelength. Each of the second multiplexing devices is coupled to the first multiplexing device by one of the channel lines. Each second multiplexing device separates X number of subscriber signals carried over the respective channel line onto Y number of output lines by wavelength. Each of the Y number of wavelengths subscriber signals carried over a first of the channel fibers is associated with a different one of the output fibers of the respective second multiplexing device. Each of the X number of subscriber signals carried over a first of the output fibers of each second multiplexing device is associated with a different one of the channel fibers.
