Abstract
An optical wavelength division multiplexed network system of this invention is designed to permit communications between any of a plurality of nodes via a main trunk line constructed by interconnecting the nodes by use of an optical fiber in a ring form and includes a multi-wavelength light source for multiplexing and transmitting a plurality of lights having different wavelengths, wherein each of the nodes includes an ADM for extracting light of a particular wavelength among the lights of a plurality of wavelengths transmitted via the main trunk line into the node and inserting the light of the preset wavelength from the node into the optical fiber acting as said main trunk line, at least one optical receiver for receiving part of the light extracted by the ADM, and a modulator for modulating light extracted by ADM with data to be transmitted and send the light back to the ADM and on to the main trunk line.
