1. wavelength division multiplexing light communication system, this system comprises transmitter and the receiver by the photoconduction link;

  • Described transmitter comprises;

    A) be used for sending along described photoconduction the device of the optical channel of a plurality of carrying communication services, every optical channel has carrier wavelength separately.B) be used for before sending to described receiver optics along described photoconduction amplify described a plurality of carrying communication services optical channel image intensifer andC) unit is inserted in the monitoring that is used for producing the monitor optical channel in the photoconduction downstream of being coupled to described image intensifer;

    AndIn case in described photoconduction, break down, just be used for forbidding the control device of described image intensifer work, described control device utilizes described monitor optical channel to judge when described photoconduction can be reused for the communication purposes;

    Wherein, in case forbidden the work of described image intensifer, described monitoring is inserted the unit and be can be used for producing described monitor optical channel with pulse mode subsequently;

    Wherein, each pulse of described monitor optical channel has enough width to allow rebuliding of frame aligning.
