| 摘要 |
<p>Present invention relates to an optical communication system, a method, and the use of a network module in an optical communication system. The optical communication system comprises a network having at least one optical fibre 22. The total bandwidth of each fibre is divided into a number of wavelength bands. Each wavelength band has a channel, ?1- ?n, being able to carry information. The optical system according to the invention is characterised in that channels are interleaved for counter-directional transmission, wherein information is transmitted on a channel in one direction, while information on adjacent channels on the same fibre is transmitted in the opposite direction. Thus, a method for transmitting information over an optical communication system according to the present invention comprises the step of transmitting information on one channel in one direction, while information on adjacent channels on the same fibre is transmitted in the opposite direction. The invented method and system have one advantage in that it suppresses the cross talk effect between adjacent channels.</p> |
