Abstract

A novel optical transmission device is disclosed, including a plurality of optical cross-connect (OXC) units each including the same configuration, and a plurality of transponder aggregator (TPA) units each including the same configuration. The combination of the number of the optical cross-connect units and the number of the TPA units may be any combination. None of the OXC units is connected to each other, and each of the OXC units is connected to all the B TPA units. The wavelength of an optical signal is any wavelength, the input/output paths of the TPAs are any input/output paths, an optical signal can be branched/inserted without collision, and the CDC functions are included.

Dependent claims

An optical transmission device comprising:

A optical cross-connect (OXC) units, each of the A OXC units including M input ports that receive a wavelength-multiplexed (WDM) signal, and M output ports that output a rerouted WDM signal;
and
B transponder aggregation device (TPA) units, each of the B TPA units outputting at least a part of the WDM signal from the input ports to any of N DROP ports and outputting, from any of the output ports, an optical signal input from one of N ADD ports,
wherein each of the A OXC units is not connected to each other, and
each of the A OXC units is connected to all of the B TPA units.
