Description
Technical field
The present invention relates to a kind of photoswitch, particularly a kind of utilize straight line to straight line and optical fiber to optical fiber type optical fiber to bit formula mechanical optical switch.
Background technology
Photoswitch is one of significant components in the optical communication, can carry out directly, interlock or transmission in many ways light signal in optical fiber network system.It is after earlier the light signal of importing being converted to electric signal that past is used wider photoswitch, electric signal is done the path to be switched, be that light signal is exported in specific optical fiber again with electrical signal conversion, this mode is complexity and consumes energy not only, is unfavorable for that following fiber optic network is universal.
Along with the continuous expansion in fiber optic applications field, in order to obtain desired optical signal transmission path in optical transmission system, the conversion of light signal between different fiber becomes very necessary, thereby a desirable photoswitch becomes important optical module.Typical photoswitch has one or more light input ends and plural at least light output end, is used for the mutual conversion or the logical operation of the light signal of optical transmission line or integrated optical circuit.
According to its principle of work, photoswitch can be divided into mechanical type and on-mechanical formula two big classes.Mechanical optical switch moves by optical fiber or optical module, and light path is changed.
Moving fiber formula photoswitch, its end that inputs or outputs in the end is fixing, the other end can move, and realizes the switching of light path by mobile free fiber.Its shortcoming is: on the one hand for fear of extra added losses, input optical fibre needs accurately to aim at output optical fibre, and this will increase manufacturing cost and complicacy; Optical fiber moves under the unprotect device and is easy to lose on the other hand, and adds that protective device can make the optical fiber pliability reduce.
Moving optical assembly formula photoswitch is by optical module light path to be changed, as: mobile sleeve pipe, mobile reflective mirror, mobile prism or the like.As related U.S. patent the 4th, 790, disclose one for No. 621 and utilized moving of six prisms and change the photoswitch of light path.United States Patent (USP) the 4th, 261, No. 638 disclosed is one to realize the photoswitch of the corresponding conversion of light path light signal by rotatable reflection subassembly.Above-described photoswitch is the accurate location after satisfying optical module and moving, and therefore, the manufacturing technology difficulty is higher, and, difficultly in the manufacture craft of reality reach desirable requirement, therefore, the optical loss of photoswitch is bigger.
Notification number is 6,044,186 United States Patent (USP), and it utilizes the relay (relay) of seesaw shape to change the position of input optical fibre termination, makes it aim at another side output optical fibre termination, reaches the effect of the direct contraposition of optical fiber.Its shortcoming be optical fiber on the switching device shifter when contraposition because of preloading power and groove reaction force acts, the optical fiber bracketed part causes flexural deformation, is the contraposition relation of curve to straight line when making the direct contraposition of two optical fiber.If being deformed into the optic fibre end of curve places long-time in some switching positions, then this optic fibre end can't be returned to original rectilinear form by curve shape, accurately contraposition when so switching another position, and can lose original aligning accuracy after the long-time continuous switching.Shortcomings such as this kind design has the assembling difficulty, aligning accuracy is wayward and keep.
Summary of the invention
In order to solve the problem of aligning accuracy difference of the prior art, be necessary to provide a kind of photoswitch that reduces bit errors.
A kind of photoswitch comprises a pedestal; One optical fiber switching device shifter is fixed in this pedestal one side; One output optical fibre stationary platform is fixed in the opposite side of pedestal, and is relative with this light path switching device; One input optical fibre fixed sleeving is accommodated an input optical fibre, is fixed in this light path switching device; Reach two output optical fibres, be individually fixed in a groove of output optical fibre stationary platform.Wherein the termination of this input optical fibre is stretched out outside the input optical fibre fixed sleeving and is extended in this groove and the contraposition of output optical fibre termination.
Compared with prior art, photoswitch of the present invention has straight line to straight line and the optical fiber optical fiber contraposition characteristic to optical fiber.The termination of input optical fibre and the termination of output optical fibre directly are aligned with each other transmits, and when input optical fibre and output optical fibre switching contraposition, the end portion of two optical fiber can reduce bit errors linearly to the straight line contraposition; And optical fiber is the mode of utilizing two optic fibre ends to be aligned with each other to optical fiber, does not need collimating apparatus can allow the light signal in the optical fiber directly transmit.The termination of the termination of the input optical fibre of this photoswitch and output optical fibre is open contraposition simultaneously, can conveniently set up the alignment situation of optical detection apparatus Direct observation optic fibre end, the position that cooperates piezoelectric micromotion platform control input and output optical fibre, can develop automatic assembly equipment, when reducing photoswitch assembling in the past, need expend a large amount of artificial expensive costs.Use automation equipment also can promote the assembling yield, promote the production efficiency of photoswitch whereby.
