Abstract
The utility model provides a mechanical optical switch. By using the mechanical optical switch of the utility model, a problem that the current mechanical optical switch can not realize a large branching ratio can be solved. The mechanical optical switch comprises an input fiber and an output fiber. The input fiber is connected with one input collimator arranged on an input collimator pedestal. The output fiber is connected with a plurality of output collimators arranged on an output collimator pedestal respectively. By using the mechanical optical switch provided in the utility model, the large branching ratio can be realized. The structure of the mechanical optical switch is simple and cost is low.
Description
Technical field
The present invention relates to a kind of mechanical optical switch, the technology that belongs to that Fiber to the home.
Background technology
At present, the optical link monitoring system mainly adopts optical time domain reflectometer detecting link performance, and in order to realize the sizable application of monitoring system with low cost, prior art adopts the l:N photoswitch to make the method for N incoming end overhead cost more.
It specifically is that photoswitch is selected a passage output beam by Control Component, as the l:4 photoswitch 1 input end, 4 output terminals is arranged; When work, light beam enters from input end, can control by 4 instructions and select the passage of an output terminal in 4 output terminals to export the light beam that enters input end, realizes being connected of this output terminal passage and input end passage.
Present mechanical optical switch all adopts control assembly such as stepper motor etc., and control input end optical fiber moves or catoptron moves to realize the selection of light path.The input end of mechanical optical switch and output terminal all adopt optical fiber collimator to carry out light beam transmitting-receiving, but existing machinery formula photoswitch branching ratio is difficult to do greatly, so its application limit is very big.
Summary of the invention
The utility model provides a kind of mechanical optical switch, has mainly solved existing machinery formula photoswitch and can't realize the problem of branching ratio greatly.
Concrete technical solution of the present utility model is as follows:
This mechanical optical switch comprises input optical fibre and output optical fibre, and input optical fibre is connected with an input collimating apparatus on being arranged on input collimating apparatus pedestal, output optical fibre respectively be arranged on the output collimator pedestal on a plurality of output collimators be connected; Be connected with the control and the driver element that drive the rotation of input collimating apparatus pedestal for control on the described input collimating apparatus pedestal, described a plurality of output collimator is rounded to be arranged on the output collimator pedestal, and the end face of a plurality of output collimators or the tangent plane of end points are positioned at same plane; The circle that each circle center line connecting of center of circle movement locus forms in the described input collimating apparatus rotary course circle and a plurality of output collimators forms is parallel and radius equal, and the input collimating apparatus pedestal center of circle and output collimator pedestal circle center line connecting are perpendicular to input collimating apparatus pedestal and output collimator pedestal.
Above-mentioned input collimating apparatus pedestal is identical with output collimator pedestal radius.
Advantage of the present utility model is:
Can realize bigger branching ratio by the mechanical optical switch that the utility model provides, and this mechanical optical switch is simple in structure, cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
1-input collimating apparatus, 2-output collimator, 3-input collimating apparatus pedestal, 4-output collimator pedestal,
