Abstract
A node for a multi-plane optical network is optically connectable, for each node of at least two other nodes of the multi-plane optical network through respectively two or more optical links to the other node. The node includes one or more wavelength selective switches (WSSs) having a set of ports. The node receives, with a port, an optical signal from an optical link of a first other node. The one or more WSSs provide at least a frequency sub-band of the optical signal from the port through another port to another optical link of the first other node or a second other node. The optical link and the another optical link are associated with one plane and one other plane of the multi-plane optical network, respectively.
