Abstract
An optical communication network includes at least one optical transmission path, a plurality of terminals connected to the optical transmission path, a plurality of optical nodes for receiving and transmitting an optical signal between the optical transmission path and the terminals, and a controller for controlling the intensity of a signal output from each optical node so as equalize its intensity with the intensity of a signal input to each optical node from the optical transmission path. In this optical communication network, the loss of a signal's intensity is determined solely by the total extension length of the optical transmission path, so that the optical modes can be freely re-connected in the network.
