  • Multichannel optical communication system and method utilizing wavelength and coherence division multiplexing
    Patent number: 7061657
    Abstract: Method and system thereof for transmission of several coherence division multiplexed (CDM) optical signals via one wavelength division multiplexed (WDM) transmission channel of a multichannel WDM telecommunication system to extend the network capacity to a theoretical limit. A broadband optical source generates light within the spectral range of at least one WDM transmission channel. Several CDM channels share this spectral range to transmit and detect phase modulated optical signals through optical fiber links.

  • Method and system transmitting optical signals generated by multi-line sources via WDM optical network
    Patent number: 6607311
    Abstract: A transmission of optical signals generated by multi-line optical sources is provided via multichannel WDM optical network. Each multi-line optical source generates optical spectral lines within designated spectral range associated with the spectral window allocated for corresponding WDM channel, and comprises a plurality of spectral lines. Spectral lines are substantially narrower than the spectral separation between the lines.
