OPTICAL DEMULTIPLEXING APPARATUS AND METHOD FOR MULTI-CARRIER DISTRIBUTION

摘要

An optical demultiplexing apparatus and method for multi-carrier distribution are provided. The optical demultiplexing apparatus may include a demultiplexer and a carrier distributor. The optical demultiplexing apparatus and method allow efficient demultiplexing of a multi-carrier light source by using a single demultiplexer even when a carrier spacing of the light source varies.

主权项

1. An optical demultiplexing apparatus comprising:
a demultiplexer configured to demultiplex a received multi-carrier light source according to a predesignated period; and a carrier distributor configured to, in a case where a wavelength spacing of the demultiplexed multi-carrier light source is set to be space S1 or space S2, which is greater than space S1, and the wavelength spacing can be switched between space S1 and space S2, determine an output wavelength spacing and bandwidth of output ports based on information about space S1 and space S2, and distribute carriers of the demultiplexed multi-carrier light source based on the calculated output wavelength spacing and bandwidth, such that the output ports are disposed to have the calculated wavelength spacing and a wavelength of a respective carrier is located within the calculated bandwidth of a respective output port.
