Abstract
An optical switch includes an input port (21) having an input fiber (211), an output port (22) having a plurality of output fibers (221), a prism assembly (23) having a plurality of prisms, a holder (25), a driving device (27) and a base (26). The input port, the output port and the driving device are mounted on the base. The holder is slidingly engaged with the base and defines a plurality of mounting holes arranged in a line, and each mounting hole accommodates a prism. As the holder is moved by the driving device, each prism moves, one at a time, into an optical path between the input and output fibers, and can deflect the light beams from the input fiber in different directions, thereby, switching the input light beams to different, predetermined output fibers.
Claims10
An optical switch for switching light beams from one input fiber between a plurality of output fibers, comprising:
- a first collimating lens aligning with the input fiber;
- a second collimating lens aligning with the output fibers;
- a prism assembly being arranged between the first and second collimating lenses comprising a plurality of prisms;
- a holder defining a plurality of through holes arranged in a line for accommodating said prisms therein;
- and
- wherein, each prism can be moved, one at a time, into an optical path between the input and output fibers, said each prism can thereby deflect the light beams coming from the input fiber in a determined different direction, thereby, switching the input light beams between different output fibers.
An optical switch for switching light beams from one input fiber between a plurality of output fibers, comprising:
- a first collimating lens aligning with the input fiber;
- a second collimating lens aligning with the output fibers;
- a prism assembly being arranged between the first and second collimating lenses comprising a plurality of prisms;
- a holder defining a plurality of through holes arranged in a line for accommodating said prisms therein;
- and
- wherein, each prism can be linearly moved, one at a time, into an optical path between the input and output fibers, said each prism can thereby deflect the light beams coming from the input fiber in a determined different direction, thereby, switching the input light beams between different output fibers.
An optical switch for switching light beams from one input fiber between a plurality of output fibers, comprising:
- a first collimating lens aligning with the input fiber;
- a second collimating lens aligning with the output fibers;
- a prism assembly being arranged between the first and second collimating lenses comprising a plurality of prisms;
- a holder defining a plurality of through holes arranged in a line for accommodating said prisms therein;
- and
- wherein, each prism can be moved, one at a time, into an optical path between the input and output fibers, said each prism can thereby deflect the light beams coming from the input fiber in a determined different direction, thereby, switching the input light beams between different output fibers;
- wherein
- the output fiber include bared fibers supported by a core and jacketed fibers supported by a support portion axially located outside of the core.
