1. an optical switching device, it comprises the down link optical switch components for switching the downlink optical signals sent by central apparatus, with the up link optical switch components for switching the uplink optical signal sent by multiple remote equipment, described optical switching device comprises:

  • For the downlink optical signals sent by central apparatus being converted to the first light/electric converting member of first signal of telecommunication;

    For being separated into the branch components of Part I and Part II from first signal of telecommunication;

    For converting the Part II of first signal of telecommunication to downlink optical signals, and by the first electrical/optical parts of this downlink optical signals input down link optical switch components;

    For the uplink optical signal exported from up link optical switch components being converted to the second light/electric converting member of second signal of telecommunication;

    For the composite component of the signal of telecommunication compound relevant with uplink data packet that second signal of telecommunication and the Part I based on first signal of telecommunication are generated;

    WithThe signal of telecommunication for being exported by composite component converts uplink optical signal to, and this uplink optical signal is sent to the second electrical/optical parts of central apparatus.
