APPARATUS AND METHOD FOR OPTICAL COMMUNICATION

摘要

An apparatus and a method for optical communication are disclosed. The optical communication apparatus mounted to a first node in a linear network connected through an optical transmission path between a plurality of nodes comprises: a multiplexer which receives a plurality of optical signals having different wavelengths from each other, and outputs a first multi-wavelength signal wherein the plurality of optical signals are coupled; and a first optical coupler which separates the first multi-wavelength signal into multi-wavelength signals to be transmitted to two or more neighboring nodes different from each other.
