Optical system for transmitting information over optical communication system using interleaved channels for counter-directional transmission over channels in both directions

摘要

The total bandwidth of each optical fiber (22) is divided into a number of wavelength bands, each with a channel being able to carry information, while the channels have two adjacent channels as closest neighbors. In the fiber, the channels are interleaved for counter-directional transmission and information in the odd and even channels is transmitted in opposite directions. AN Independent claim is included for an optical transmission method.
