The second network portion may be coupled with the second network and the first network portion of the interconnection node such that optical signals may be routed between the second network and the first network. The third network portion may be coupled with the third network and the first network portion of the interconnection node such that optical signals may be routed between the third network and the first network.

摘要： A reconfigurable optical add/drop multiplexer (ROADM) with a multiplexer, demultiplexer, and a wavelength cross-connect unit provides directionless capabilities. The ROADM allows a signal not to be limited to a particular direction when added at an optical network node, for example. The signal can be sent to other directions of the optical network node. Furthermore, the ROADM allows the wavelengths of add and drop signals to be changed and hence is “colorless.”
