1. A system, comprising:
a first type of switching module at a first network degree of a first direction in a node of a network, the first type of switching module configured to receive optical signals and transmit the optical signals having a first set of wavelengths;
a second type of switching module in communication with the first type of switch at the first network degree, the second type of switching module configured to receive the optical signals having the first set of wavelengths from the first type of switching module; and
a third type of switching module in communication with the second type of switching module and an add/drop module, the third type of switching module configured to route the optical signals having the first set of wavelengths to or from the add/drop module at a predetermined network degree, wherein:
the add/drop module is configured to add or drop one or more wavelengths of the first set of wavelengths, and
the add/drop module is separate from the third type of switching module.
