Abstract:
1. A communication method, comprising: transmitting a first frame at a baud rate on a first optical channel having a first wavelength, the first frame having a bit length, the first frame including a first payload having first data payload bits, the first frame further including first forward error correction bits such that the first frame has an associated first coding gain and first payload data rate; transmitting a second frame at the baud rate on the first optical channel, the second frame having the same bit length as the first frame and including a second payload having second data payload bits, the second frame further including second forward error correction bits, a number of the first data payload bits being more than a number of the second data payload bits, and a number of the first forward error correction bits being less than a number of the second forward error correction bits, such that the second frame has an associated second coding gain greater than the first coding gain and a second payload data rate less than the first payload data rate; receiving a plurality of information bits, a number of the plurality of information bits being equal to the number of said first data payload bits, first ones of the plurality of information bits being included in the second frame as said second data payload bits; generating a third frame including a third payload having third payload bits, second ones of the plurality of information bits, other than the first ones of the plurality of information bits, being included in the third frame as said third data payload bits; and transmitting the third frame on a second optical channel having a second wavelength different than the first wavelength.
