Abstract:
A method of transmitting optical signals generated by multi-line source via WDM multi-channel optical network, comprising the steps of:generating light within plurality of designated spectral ranges &Dgr;&OHgr; of respective plurality of WDM optical channels, each said designated spectral range &Dgr;&OHgr; comprising N spectral lines, wherein N is an integer greater than zero, each said spectral line having a spectral width &Dgr;&ohgr;, said &Dgr;&ohgr;<modulating said light within each WDM optical channel by a respective electrical signal for obtaining a respective modulated optical signal; propagating modulated optical signals via respective WDM optical channels via an optical fiber of said WDM optical network; and detecting said propagated optical signal, wherein products of non-linear optical interaction of said propagated optical signal within said plurality of WDM optical channels are suppressed; and wherein the ratio of &Dgr;&OHgr;/Nâˆ’1 is a spectral separation between adjacent spectral lines, said spectral separation exceeding a spectral bandwidth of said electrical signal.
