Mechanical photo switch

Abstract

The invention discloses a mechanical light switch, comprising a first optical fiber module and a second optical fiber module arranged in the corresponding position of the first optical fiber module, wherein the first optical fiber module comprises a first optical fiber and a first optical fiber switching device, the second optical fiber module comprises at least two second optical fibers and a second optical fiber switching device. The tip of the first optical fiber switching device which controls the first optical fiber is shifted in horizontal or vertical direction, and the tip of the second optical fiber switching device which controls the second optical fiber is shifted in the vertical direction of the moving direction of the tip of the first optical fiber to enable the first optical fiber to be on the contraposition of the second optical fiber.

Description

technical field [0001] The present invention relates to an optical path switching element used in an optical fiber communication system, in particular to an optical switch that utilizes mechanical switching and is directly aligned with bare optical fiber ends (fiber to fiber). The optical switch of the present invention passes through the The design can increase the pass rate of the optical switch and at the same time improve the accuracy of the optical fiber alignment. Background technique [0002] The optical switch is one of the important components of the all-optical network, which can be used for direct, interleaved or multi-party transmission of optical signals in the optical fiber network system. Optical switches developed in the past use photoelectric conversion to first convert the input optical signal into an electrical signal, then switch the signal path, and finally convert the electrical signal into an optical signal and output it through a specific optical fibe...

AI Technical Summary

Problems solved by technology

The disadvantage is that the optical fiber on the switching device is subjected to pre-pressure and groove reaction force during alignment, and the cantilever part of the optical fiber is bent and deformed, so that the alignment relationship of the two optical fibers is a curve to a straight line when the two optical fibers are directly aligned.

If the optical fiber end deformed into a curve is placed in a certain switching position for a long time, the optical fiber end will not be able to return from the curved shape to the original straight line shape, so when switching to another position, it will not be able to accurately align, and it will continue for a long time After switching, the original alignment accuracy will be lost

This design has disadvantages such as difficult assembly and difficult control and maintenance of alignment accuracy.
