Background technology
Along with communication and the fast development of information network technique, the requirement of people to capacity, communication speed etc. is more and more higher, and traditional telecommunication has been difficult to meet the demands.A kind of brand-new Fibre Optical Communication Technology-optical cross connection technology of current appearance will fundamentally solve electronic bottleneck problem, thus realize all optical communication.Photoswitch is the Primary Component in optical cross connection and dense wave division multipurpose (DWDM) system.Photoswitch coordinates with dense wave division multiplexer, can realize the Random route of each wavelength, realize All-optical switching.In recent years, about the research report of photoswitch is shown in many day by day, many manufacturers also started release or developing all kinds of photoswitch.Usually, photoswitch can be divided into: micro-electromechanical array switch, magneto-optic shutter, liquid crystal shutter, thermo-optical switch, electrooptical switching and acoustooptic switch etc.Exchange media according to photoswitch divides, and photoswitch can be divided into: free space Switched Optical switch and waveguide Switched Optical switch.Micro-electromechanical array switch manufacture craft requires high, and device is expensive; There is slow problem (0.1 ~ 1ms level) equally in magneto-optic shutter and liquid crystal shutter.
Summary of the invention
The object of the invention is the various defect existed for existing photoswitch and a kind of electrodynamic mechanical type photoswitch provided.
The present invention is achieved by the following technical solution:
A kind of photoswitch, comprises box body and lid, has a cavity in box body, box body has intelligent acess mouth and optical fiber delivery outlet, described optical fiber delivery outlet is multiple optical fibre array, and multiple optical fibre array is fixed on box body by fiber array support, has the regulating device of switching-over light path in box body.
Described regulating device comprises motor, U-shaped block, guide rail, slide block, screw mandrel and photoelectric sensor, the xsect of U-shaped block is U-shaped structure, the inner bottom part of box body is arranged on bottom U-shaped block, motor is arranged on the side of U-shaped block, the output terminal connection wire rod of motor also drives screw mandrel to rotate, guide rail is positioned at the inner bottom part of U-shaped block, guide rail and screw mandrel be arranged in parallel, slide block is installed on guide rail, and slide block can slide by opposite rail, screw mandrel runs through slide block and arranges, and slide block coordinates with wire rod thread, slide block is provided with the optical fiber fixed support for fixing single fiber array, optical fiber fixed support is provided with single fiber array, single fiber array one end is by the external optical fiber of intelligent acess mouth, the other end is installed on optical fiber fixed support towards multiple optical fibre array.
