Abstract
An optical transmitter may receive and encode a first group of bits into first encoded data and second encoded data. The optical transmitter may supply a first sub-carrier carrying a first symbol and a second sub-carrier carrying a second symbol. The first symbol and the second symbol may be based on the first encoded data and the second encoded data, respectively, such that the first sub-carrier has a first polarization state comprising first and second polarization components, and the second sub-carrier has a second polarization state comprising first and second polarization components. The first polarization state may be substantially orthogonal to the second polarization state. An optical receiver may receive the first symbol via the first sub-carrier, may receive the second symbol via the second sub-carrier, may decode the first symbol and the second symbol into a second group of bits, and may output the second group of bits.
