Responsive to control signals from the remote node, the number of used sub-carrier channels is set to optimize optical performance of the WDM channel. | 2010-09-23 |
20100239260 | OPTICAL TRANSMISSION APPARATUS, OPTICAL COMMUNICATION METHOD, AND OPTICAL COMMUNICATION SYSTEM - An optical transmission apparatus and method thereof is provided. The optical transmission apparatus includes transmission units configured to transmit lights having different wavelengths, a multiplexing unit configured to multiplex lights transmitted from the transmission units, and a controller configured to control wavelengths of the lights, where the controller includes a wavelength spacing processing unit that controls a spacing between the wavelengths on the basis of reception state information of an apparatus that has received the multiplexed light. | 2010-09-23 |
