Abstract
A method comprising: receiving a multiplexed optical signal comprising optical channels for N wavelengths, N being a positive integer greater than or equal to two; and separating the multiplexed optical signal into a first multiplexed light and a second multiplexed light, each of the first multiplexed light and the second multiplexed light having the same polarization, and each of the first multiplexed light and the second multiplexed light having N wavelengths; separating the first multiplexed light into a plurality of first lights, each having a different wavelength; separating the second multiplexed light into a plurality of second lights simultaneous with separating the first multiplexed light into the first lights, each of the second lights having a different wavelength; and generating optical parameters for each optical channel in the N wavelengths using the first light and the second light for each wavelength.
