1. the optimal combination system of a time-division optical cross connect is characterized in that:

  • with N independent light channel, respectively behind optical fiber collimator;

    Optical fiber collimator is arranged around same electromagnetism rotating shaft, is arranged in the traffic circle divider by the optical channel order, in the cutting on the disk of electromagnetism rotating shaft;

    Arrange single-mode fiber or optical fiber collimator, when arrange on the disk be single-mode fiber the time, the outer optical fiber collimator end face of arranging of its end face and disk is coupled;

    When arrange on the disk be optical fiber collimator the time, the outer optical fiber collimator end face of arranging of its end face and disk has the gap of 5mm, the other end of single-mode fiber or optical fiber collimator passes the endoporus at electromagnetism rotating shaft center;

    Connect outside wavelength division multiplexer respectively;

    Single-mode fiber on the disk or optical fiber collimator are driven by the electromagnetism rotating shaft, the high speed deflection collimating apparatus that the outside is aimed in addressing in the deflection angle allowed band;

    When the some collimating apparatuss on single-mode fiber or the optical fiber collimator aligning outside divider;

    Light signal is connected, and through the high repetition frequency address scan, multichannel is realized that the light exchange connects;

    The input optical channel is aimed at the different collimating apparatuss on the divider through single-mode fiber on the disk or optical fiber collimator high speed deflection addressing;

    Time slot with different reaches output port, places the electromagnetic deflector and the photoswitch electromagnetic deflector of placing M group 1 * N of the photoswitch of 1 * N by several, becomes the time-division optical cross-connect of the multi-channel port of unlimited M * N to multi-channel port through the expansion permutation and combination;

    Equally, the light path of each port to port is communicated with through each driver acquiescence of programming Control and connects completion.
