1. A wavelength-selective switch (WSS) comprising:

  • multiple parallel non-cascaded WSSs;

    at least one add path coupled to an input of at least one of the WSSs, the add path configured to carry optical traffic from at least one tributary path; and

    an optical coupler optically coupled to the multiple parallel non-cascaded WSSs.
