Abstract
A method may include transmitting, by an optical device, a first set of channels using a first baud rate. The first set of channels may be attenuated during transmission by a filter associated with a wavelength selective switch. Transmitting, by the optical device, a second set of channels using a second baud rate. The second set of channels may be attenuated during transmission by the filter associated with the wavelength selective switch. The first set of channels and the second set of channels may be included in a super-channel. The first baud rate may be selected based on a first signal quality factor associated with attenuation by the filter associated with the wavelength selective switch. The second baud rate may be selected based on a second signal quality factor associated with attenuation by the filter associated with the wavelength selective switch.
