Selectively Mapping of Bit Streams Across Each of a Plurality of Optical Fibers

A method of an optical system, comprising:

• generating, by each of N lasers of each of a plurality of wave-division-multiplexing (WDM) transceivers of an optical transmission system, an optical communication signal having a carrier optical frequency within a corresponding channel that is different than a carrier optical frequency and corresponding channel of each of other N-1 different lasers of the N lasers;
• coupling each of the plurality of WDM transceivers to one of Y optical fibers, wherein an output of each of the WDM transceivers is transmitted over a corresponding one of the Y optical fibers when the corresponding one of the Y optical fibers is operational;
• receiving, by each of modulators of the WDM transceivers, N bit streams of a plurality of input streams;
• modulating the optical communication signal of each of the N lasers with corresponding N bit streams;
• receiving, by a reconfigurable switch, the plurality input bit streams;
• generating, by each of a plurality of bit source devices, a plurality of bit streams;
• and
• selectively connecting each of the plurality of bit streams of each of the bit sources to an input of one of the plurality of WDMs for modulation onto the N carriers signals of the one of the plurality of WDMs for communication across a corresponding one of the Y optical fibers, wherein at least one of the bit streams of one of the plurality of bit source devices is communicated across a different one of the Y optical fibers than another one of the bits streams of the one of the plurality of bit source devices.
