Abstract:
1. An optical apparatus, comprising a plurality of ports having first, second, and third ports, which apparatus is adapted to route optical signals between different ports based on wavelength, wherein: the optical signals correspond to two or more sets of channels, each set having one or more channels with a corresponding bandwidth value; at least two different sets of channels have different bandwidth values; and the optical apparatus comprises a routing device adapted to: the first group of channels is a first subset of a first set of channels; the second group of channels includes a second set of channels and a second subset of the first set of channels; channels from the first set occupy a first spectral band, wherein channels from the first subset are interleaved with channels from the second subset; channels from the second set occupy a second spectral band distinct from the first spectral band; and the routing device comprises:
