Description
Technical field
The present invention relates to a kind of cable that gives and apply the extra device reversed, particularly relate to a kind of fiber PMD values that reduces
Device.
Background technology
Fiber PMD values, full name is Polarization Mode Dispersion, i.e. polarization mode dispersion, as optical fiber certainly
The important parameter of body, PMD value mainly has influence on high speed fibre transmission and dense wave division multipurpose (DWDM) technology, so obtaining low
PMD value becomes the common objective of each optical fiber production factory.
Currently, each producer gives method that optical fiber additionally reverses to reduce PMD value, shown in Fig. 1 when all using drawing optical fibers
It is to use more universal a kind of solution principle figure, as it can be seen, arrange two groups of runners in orthogonal both direction, wherein turning below
Wheel 16,17 is to rub with the hands to turn round wheels, together with runner 16 fits tightly with runner 17.Runner 18,19 above is to guide wheels, runner
Having the gap slightly larger than fibre diameter between 18 and runner 19, when optical fiber 20 is from top to bottom through two wheels, optical fiber is by runner
16 and runner 17 clamp with an appropriate clamping force, meanwhile, runner 16 and runner 17 can swing one in opposite directions along shown by arrow direction
Little angle, and reciprocally swinging, when so passing runner 16 and the runner 17 of reciprocally swinging along with high speed fibre, optical fiber just produces
Give birth to the torsion of both forward and reverse directions, thus reduce PMD value purpose.The effect guiding runner 18,19 is location optical fiber, prevents light
Fine stranding with the hands skids off stranding twist wheel 16,17 when turning round.The PMD device made based on this principle uses in actual production in a large number, and it is deposited
Shortcoming mainly: first, because optical fiber is clamped by two runners, so runner machining accuracy and runner dynamic balancing there to be higher wanting
Ask, fibre coating otherwise can cause damage, the method for direct pressed fiber also easily cause runner and wear and tear at optical fiber contact,
The runner life-span is substantially reduced；Secondly, the clamping force between runner 16 and runner 17 is difficult to accurately measure, and is difficult to keep perseverance
Fixed, cause stranding to turn round during effect fashion bad uncontrolled；Again, these two groups of runners are easily generated shake when motion, thus to optical fiber
Coating causes damage and makes the intensity losses of optical fiber.
Summary of the invention
For the shortcoming of existing apparatus, it is an object of the invention to provide a kind of simple in construction, reliability height, be difficult to light
Fine coating causes damage and the device that reduce fiber PMD values little on fiber strength impact.
The technology contents of the present invention is: a kind of device reducing fiber PMD values, it is characterized in that it includes frame, upper guiding
Runner, rub with the hands twist wheel, lower guiding runner, line slideway, slide block, withstanding tight block, stranding twist wheel contiguous block, bearing, cam, extension spring,
Extension spring fixed block and motor；Outer wheel surface at upper guiding runner and lower guiding runner is provided with v-depression, is rubbing with the hands outside twist wheel
Wheel surface is provided with trapezoidal groove；Motor is arranged in frame, and cam is arranged on motor, and line slideway is arranged on lower cam end
In frame, rub twist wheel contiguous block with the hands and be arranged on line slideway by slide block, rub twist wheel contiguous block one end with the hands and withstanding tight block is installed,
Rubbing the twist wheel contiguous block other end with the hands and be connected and installed with stranding twist wheel, upper guiding runner is arranged in the frame rubbing twist wheel upper end with the hands,
Lower guiding runner is arranged in the frame rubbing twist wheel lower end with the hands；Bearing is arranged on withstanding tight block, and extension spring fixed block is arranged on stranding and turns round
On runner contiguous block, extension spring one end is connected with motor, and the extension spring other end is connected with extension spring fixed block, and extension spring makes bearing paste with cam
Tightly.
The present invention is the most advantageously: simple in construction, reliability are high, due to upper guiding runner,
Rub twist wheel and lower guiding runner with the hands and optical fiber is not had extruding force, so the coating of optical fiber will not be produced damage, strong to optical fiber
Degree impact is the least.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of the present invention.
Fig. 3 is to rub twist wheel with the hands to rub the principle schematic turning round optical fiber with the hands.
Specific implementation method
As in figure 2 it is shown, a kind of device reducing fiber PMD values, it is characterized in that it includes frame 1, upper guiding runner 2, rubs with the hands
Twist wheel 3, lower guiding runner 4, line slideway 5, slide block 6, withstanding tight block 7, stranding twist wheel contiguous block 8, bearing 9, cam 10, extension spring
11, extension spring fixed block 12 and motor 13；Outer wheel surface at upper guiding runner 2 and lower guiding runner 4 is respectively equipped with v-depression
14, it is provided with trapezoidal groove 15 at the outer wheel surface rubbing twist wheel 3 with the hands；Motor 13 is arranged in frame 1, and cam 10 is arranged on motor 13
On, line slideway 5 is arranged in the frame 1 of cam 10 lower end, rubs twist wheel contiguous block 8 with the hands and is arranged on line slideway 5 by slide block 6
On, rub twist wheel contiguous block 8 one end with the hands and withstanding tight block 7 be installed, rub twist wheel contiguous block 8 other end with the hands and be connected and installed with stranding twist wheel 3,
Upper guiding runner 2 is arranged in the frame 1 rubbing twist wheel 3 upper end with the hands, and lower guiding runner 4 is arranged on the frame 1 rubbing twist wheel 3 lower end with the hands
On；Bearing 9 is arranged on withstanding tight block 7, and extension spring fixed block 12 is arranged on stranding twist wheel contiguous block 8, extension spring 11 one end and motor
13 connect, and extension spring 11 other end is connected with extension spring fixed block 12, and extension spring 11 makes bearing 9 be adjacent to cam 10.
The operation principle of the present invention is: optical fiber 19 introduces from upper guiding runner 2 and rubs twist wheel 3 with the hands, then is drawn by lower guiding runner 4
Going out, cam 10 rotates under the drive of motor 13, makes bearing 9 and cam 10 be adjacent to due to extension spring 11 and cam 10 turns for irregular
Wheel, cam 10 drives stranding twist wheel contiguous block 8 linearly guide rail 5 to move back and forth by bearing 9 and withstanding tight block 7, thus drives stranding
Twist wheel 3 moves back and forth, and makes optical fiber 19 obtain in trapezoidal groove 15 in stranding twist wheel 3 and moves back and forth as it is shown on figure 3, thus reduce light
Fine PMD value, the present invention changes the stranding reciprocating amplitude of twist wheel 3 also by the rotating speed of regulation motor 13, can with this
To obtain the different forward and reverse torsional amplitudes of optical fiber.
