First time 1,000 channel WDM transmission demonstration in an installed optical fiber 126 km-span transmission trial on the JGN II testbed Nippon Telegraph and Telephone Corporation has successfully demonstrated 1,000 wavelength channel WDM (*1) transmission in an installed optical fiber for the first time in the world on the JGN II RD testbed (*2) recently. The experiment utilized the 126 km test bed between Kyoto Keihanna and Osaka Dojima, transmitting 10 times more WDM channels with 8 times density (one 8th wavelength spacing) of the commercial systems.
