Undirected cross connects based on wavelength-selective switches

摘要

Undirected cross connects are provided based on wavelength-selective switches. An undirected Cantor network is disclosed where the switch nodes are wavelength selective switches. An undirected Clos cross connect is also disclosed where one or more undirected switches are undirected Cantor networks having at least one wavelength selective switch.

1. An undirected Cantor network, comprising:
k bidirectional ports; at least one layer of bidirectional wavelength selective switch nodes configured for performing bidirectional communication of light, wherein at least a given one of said bidirectional wavelength selective switch nodes is configured for receiving a received light signal from a bidirectional wavelength selective switch node in a first layer of said undirected Cantor network, wherein said first layer is a different layer than a layer of said given one of said bidirectional wavelength selective switch nodes, and forwarding said received light signal to a bidirectional wavelength selective switch node in said first layer; and k bidirectional switches for connecting said k bidirectional ports to said at least one layer of bidirectional switch nodes.
