Abstract
The utility model discloses a fiber ring rotation polarization controller. The controller comprises a base, a plurality of supports that are fixed to the base and provided with adjusting turn buttons, and a plurality of adjusting rings with protruding ends. The protruding ends of the adjusting rings are inserted into two adjacent supports. When the adjusting rings rotate relative to the base, the fibers in the supports at the two ends of the base are deformed without limitation. The controller is not provided with fasteners in the supports to allow the fibers to freely deform without limitation when the adjusting rings rotate, so that distortion loss of the fibers is greatly reduced, effective operating distance is increased, and simplified structure and shortened equipment size are achieved. The length of the controller is one third shorter than the length of the products of the same kind. The supports are provided with fiber grooves used for allowing the fibers to pass through, so that fibers can be inserted into the controller and then handle the fiber wire jumper. Furthermore, the fiber and corresponding wire jumper are disposed inside the polarization controller, so that the external fiber can be directly screwed into a fiber connector with simple operation.
Description
Technical field
The utility model relates to a kind of fiber optic loop rotatory polarization controller, belongs to Polarization Controller field.
Background technology
Polarization Controller is at high speed optical fiber communication, coherent fiber communication, fiber laser, optical fiber tomography three-dimensional imaging, and the field such as Fibre Optical Sensor has a very important role, it is the key element that overcomes Polarization Dependent Loss and monitoring instrument polarization characteristic in optical transmission system.Along with development and the upgrading of industry, as also more and more higher in the requirement of the aspects such as size, optical fiber damage and bending loss to Polarization Controller, current Polarization Controller mainly contains: manual or electric rotary extrusion Polarization Controller, manual three fiber optic loop Polarization Controllers etc., but all there is bad etc. the defect of the large and performance of volume, as existing three ring Polarization Controller optical fiber are completely fixed at two ends, large to optical fiber damage, corresponding distortion loss is large, and structure is compact not, so size is bigger than normal.
Utility model content
Utility model object: the utility model proposes a kind of fiber optic loop rotatory polarization controller, reduced distortion loss and the damage of optical fiber.
Technical scheme: the technical solution adopted in the utility model is a kind of fiber optic loop rotatory polarization controller, comprise pedestal, several are fixed on the support with adjusting knob on pedestal, several regulating rings with protruding end, insert in adjacent stent the protruding end of described regulating ring, when regulating ring is in the time that pedestal rotates, the optical fiber in pedestal two end supports do not carry the baby yet deformation thereupon.Described regulating ring forms by two protruding ends, shrouding disc, bottom and by the tightening knob that shrouding disc and bottom are fixed together, and described bottom and two protruding ends all have the optical fiber duct of receiving optical fiber.
As a kind of improvement of the present utility model, on described pedestal, fix four supports.Described support has adjusting knob.
As another improvement of the present utility model, described Polarization Controller is provided with three regulating rings.Described support leaves the open slot penetrating for optical fiber.
Beneficial effect: the utility model does not arrange securing member in support, allow optical fiber also can not carry the baby in the time that regulating ring rotates freely deformation thereupon of ground, greatly reduce the distortion loss of optical fiber and increased EFFECTIVE RANGE, also simplify the structure and dwindled equipment size, Length Ratio like product shortens more than 1/3rd simultaneously.Meanwhile, on support, leave the optical fiber duct penetrating for optical fiber, after optical fiber can being filled in, do again optical patchcord.Also designed in addition optical fiber and corresponding wire jumper have been built in this Polarization Controller, outside optical fiber directly can be screwed in the joints of optical fibre, operated very easy.
Accompanying drawing explanation
Fig. 1 is stereographic map of the present utility model;
Fig. 2 is front view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only be not used in restriction scope of the present utility model for the utility model is described, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of various equivalents of the present invention.
As shown in Figure 1, the present embodiment fiber optic loop rotatory polarization controller comprises the pedestal 3 with bolt, on pedestal 3, is provided with four supports 4 that interval is equal along its length direction.Support 4 has the circular hole connecting along pedestal 3 length directions, and these four supports 4 are arranged point-blank.Between four supports 4, be provided with altogether three regulating rings 7 with protruding end 2.Described regulating ring 7 forms by two protruding ends 2, shrouding disc 1, bottom 8 and by the tightening knob 5 that shrouding disc and bottom are fixed together.Described bottom 8 and 2 inside, two protruding ends all have the optical fiber duct (not shown) of receiving optical fiber.Insert in the circular hole of adjacent stent 4 two protruding ends 2 of regulating ring 7, and can be around the length direction rotation of pedestal 3.Each support 4 has adjusting knob 6, and described adjusting knob 6 is meshed with described protruding end 2.
Described bottom 8 inner sides have the annular optical fiber duct of receiving optical fiber.Optical fiber is laid along optical fiber duct, and is extended out to both sides by two protruding ends 2.Artificial rotation adjusting knob 6 can drive regulating ring 7 turning perpendicular to the plane internal rotation of pedestal 3 length directions by protruding end 2.Optical fiber can be subject to the effect of stress under this drive rotatablely moving, the birefringence that stress produces makes to produce in orthogonal polarization orientation phase delay, can realize polarisation of light state freely changes, angle of regulation range can reach 0 °-270 °, even 0 °-360 °, any input polarization can be adjusted to arbitrary polarisation of light state in poincare sphere.
As depicted in figs. 1 and 2, support 4 offers the open slot 9 penetrating for optical fiber, this open slot 9 connects with support 4 upper surfaces, thereby optical fiber can be filled in from the top down and done optical patchcord again, also designed in addition optical fiber and corresponding wire jumper have been built in this Polarization Controller, outside optical fiber directly can be screwed in the joints of optical fibre, operate very easy.On the other hand, described open slot 9 can be by screwing adjusting knob 6 extrusion racks 4, so that the protruding end of regulating ring 72 is clamped in open slot 9, so just can secured adjusted ring 7 in certain position.
In the support at existing fiber ring rotatory polarization controller two ends, optical fiber is to be fixed on support by securing member.That is to say in the time that regulating ring 7 rotates, optical fiber can be subject to securing member constraint and larger distortion and extruding occur, thus be easy to damage and EFFECTIVE RANGE short.And the support 4 at pedestal 3 two ends in the present embodiment is not established securing member, can comparatively freely produce deformation, and be not subject to the constraint of securing member while making optical fiber be rotated motion distortion.Thereby greatly reduce the distortion loss of optical fiber and increased EFFECTIVE RANGE, also simplifying the structure and dwindled equipment size simultaneously, Length Ratio like product shortens more than 1/3rd.
