Abstract:
1. A method comprising: determining, by a processor, a first wavelength associated with a first signal generated by a first transmitter and a second wavelength associated with a second signal generated by a second transmitter, wherein the first signal and a second signal are combined by a wavelength selective switch (WSS), and wherein the first wavelength and the second wavelength are determined before the first signal and the second are combined by the WSS; determining, by the processor, that a difference between the first wavelength and the second wavelength does not satisfy a desired wavelength difference; determining, by the processor, whether the first transmitter was instructed to transmit the first signal at the first wavelength for network purposes; generating, by the processor, an instruction to cause one of the first transmitter or the second transmitter to modify the difference between the first wavelength and the second wavelength, wherein the instruction causes the first transmitter to modify the first wavelength when the first transmitter was not instructed to transmit the first signal at the first wavelength for network purposes, wherein the instruction causes the second transmitter to modify the second wavelength when the first transmitter was instructed to transmit the first signal at the first wavelength for network purposes, wherein generating the instruction includes determining whether at least one other instruction to modify a transmission property was sent to the one of the first transmitter or the second transmitter during a particular time period, and wherein the instruction causes the one of the first transmitter or the second transmitter to stop transmitting when the at least one other instruction was sent to the one of the first transmitter or the second transmitter during the particular time period; and forwarding, by the processor, the instruction to the one of the first transmitter or the second transmitter.
