1. An optical switch system having a protection optical path, comprising:

  • a plurality of optical input lines for carrying optical signals;

    a plurality of optical output lines; and

    an optical switch for directing light beams from the optical input lines to selected optical output lines, said optical switch comprising a plurality of miniature working mirrors for reflecting light beams in optical paths from the optical input lines to the selected optical output lines and a plurality of miniature protection mirrors movable into the optical paths in the event of a fault in light communication of one or more light beams from the input optical lines to the selected output optical lines, said miniature protection mirrors for directing light beams ultimately to the selected optical output lines.
