Patent ID: 8849114

Claim:
An optical system comprising: a compensator device having: a wavelength selection switch (WSS) to receive a first optical signal and provide first channels, associated with the first optical signal, and second channels associated with the first optical signal; a polarization beam splitter (PBS) to receive the first channels, and provide first components of the first channels and second components of the first channels, the first components being associated with a first polarization and the second components being associated with a second polarization; a photodiode that provides an electrical signal indicative of an intensity of the first channels; a first modulator to receive the electrical signal and the first components, the first modulator modulating the first components, based on the electrical signal, to provide first modulated channels; a second modulator to receive the electrical signal and the second components, the second modulator modulating the second components, based on the electrical signal, to provide second modulated channels; a polarization beam combiner (PBC) to receive the first modulated channels and the second modulated channels to provide combined modulated channels; and a coupler to receive the combined modulated channels and the second channels to provide a second optical signal to a receiver module.
