Optical switch

An optical switch for switching signals between one input fiber and a plurality of output fibers comprising:

• an input port having a collimator, the input fiber being aligned with the collimator;
• a plurality of output ports each having a collimator, one output fiber being aligned with each output port collimator;
• and
• a switching element for switching signals from the input port to any one of the plurality of output ports, comprising a rotary holder having a connecting portion and a body to which at least one counterweight is attached;
• wherein, the switching element rotates around a central axis of the connection portion of the rotary holder, and rotational balance of the rotary holder is achieved by adjusting positions of the at least one counterweight on the body.

An optical switch for switching signals between one input fiber and a plurality of output fibers comprising:

• a base having opposing first second walls, the second wall defining a center hole and a plurality of peripheral holes positioned evenly on a circumference of a circle centered on the center hole;
• an input port having an input collimator mounted in the center hole of the second wall, the input fiber being aligned with the input collimator;
• a plurality of the output ports each having an output collimator mounted in the corresponding peripheral hole, one output fiber being aligned with each output port collimator;
• and
• a switching element mounted on the first wall of the base with moveable first and second reflectors wherein the first reflector is aligned with the input port and the second reflector is aligned with a selected one of the output ports.
