BILATERAL MULTICHANNEL OPTICAL RING NETWORKS USING WDM TECHNIQUES

摘要

This invention is about the multichannel all-optical ring network. The multichannel optical ring network enhances communication network performance by decreasing signal propagation delay time in the communication network, by forming ring networks composed of a wavelength channel group of O1, O3, O5,... propagating counterclockwise and a group of O2, O4, O6,... propagating clockwise and injecting signals through the short path to the target node by the control of a node controller.
