Abstract
The present invention provides an expandable and cost-effective high capacity optical communication system using wavelength-division-multiplexing, optical direction guide means and bidirectional transmission of data over an optical waveguide. The use of interleaved bidirectional data channels reduces the minimum spacing between data channels, permitting a greater number of channels over a single optical waveguide.
