Abstract
An apparatus includes N 1×2 ingress tap couplers, a wavelength blocker array, N 2×1 egress tap couplers, and a wavelength selective cross-connect (WSX) array. A tapped branch of each ingress tap coupler is coupled to a degree drop and where N>1. The wavelength blocker array has N wavelength blocking units, each wavelength blocking unit coupled to a corresponding one of the N 1×2 ingress tap couplers. A tapped branch of each egress tap coupler is coupled to a degree add. The wavelength selective cross-connect (WSX) array is coupled between the wavelength blocker array and the N 2×1 egress tap couplers, where the WSX array includes a plurality of independently switched 2×2 WSX switches.
