Abstract
A wavelength selective switch (WSS) may include a first set of ports, each to launch a respective beam of a first set of beams, wherein the first set of beams is provided to a first position on a focal plane, and wherein a first set of wavelength channel sub-beams, included in a beam of the first set of beams, is to be incident on a particular section of a switching array. The WSS may include a second set of ports, each to launch a respective beam of a second set of beams, wherein the second set of beams is provided to a second position on the focal plane, wherein the second position is different from the first position, and wherein a second set of wavelength channel sub-beams, included in a beam of the second set of beams, is to be incident on the particular section of the switching array.
