Abstract

Recent progress of optical transmission technologies is going to realize practical systems up to 10 Gb/s. 40 Gb/s and further high speed transmission systems are now under development by introducing WDM (Wavelength Division Multiplexing) technologies to meet growing traffic demands. In such large capacity network, reliability and robustness are important issues because the increased capacity makes heavier damages to the network in case of line failure. Self-healing functions automatically restoring working lines to spare lines would be essential in the network.
