TECHNICAL FIELD OF THE INVENTION
The present invention relates to an optical fiber component test method and an optical fiber component test apparatus, and more particularly, to an optical fiber component test method for performing a strength test of an optical fiber provided in an optical fiber component used for an optical switch or the like. And an optical fiber component testing apparatus.
[0002]
[Prior art]
Generally, when a connection work on a subscriber side in an optical communication network is performed, a connection or disconnection state of each optical transmission line is checked by an optical support system in a station. At this time, a signal for measurement is individually transmitted to a number of optical fibers on the subscriber side using an optical switch. As this optical switch, a fiber selector (FS) type optical switch, which can achieve higher density than an optical switch using a connector ferrule, has been widely used.
[0003]
As shown in FIG. 5, the FS type optical switch selectively connects one or a plurality of second optical fiber wires 60 to a large number of first optical fiber wires 50. . Here, as an example, a case where two second optical fiber strands 60 are connected is shown.
The optical switch includes an array 51 having a plurality of V-grooves 52 for arranging a large number of first optical fiber strands 50 in parallel, and an optical fiber component to which two second optical fiber strands 60 are fixed. Is provided. The master head 61 is mounted on a driving device (not shown) for allowing the master head 61 to access the array 51.
The first optical fiber 50 and the second optical fiber 60 are made of an optical fiber in which the resin coating located near the tip of the optical fiber core is removed and the glass is exposed on the surface, or the surface of the glass body is made of carbon. Is a coated carbon fiber (CCF).
[0004]
The array 51 is formed by forming a V-shaped groove 52 on the surface of a silicon substrate. For example, about 400 first optical fiber strands 50 are arranged in parallel. The FS optical switch selectively connects two second optical fiber wires 60 to about 400 first optical fiber wires 50.
[0005]
As shown in FIGS. 5 and 6, the second optical fiber 60 attached to the master head 61 is fixed to the master head 61 while being inclined downward. Is set to, for example, 8 degrees.
A pressing piece 63 for pressing the second optical fiber 60 into the V-shaped groove 52 is provided at a lower portion of the tip of the master head 61.
[0006]
When connecting the second optical fiber 60 to the first optical fiber 50, first, the master head 61 is moved in the direction in which the V grooves 52 are arranged (the X direction in the drawing). Then, the second optical fiber 60 is positioned on the V-groove 52 in which the first optical fiber 50 to be connected is stored. Next, the master head 61 is moved downward (Y direction in the figure) toward the array 51 so that the tip of the second optical fiber 60 is accommodated in the V groove 52.
[0007]
As shown in FIG. 6B, when the second optical fiber 60 is placed in the V-shaped groove 52 (see FIG. 5) of the array 51, the tip of the first optical fiber 50 and the second optical fiber The ends of the wires 60 are fixed in a state where they are close to each other and face each other. Thereby, the optical axes of the first optical fiber 50 and the second optical fiber 60 are aligned in the V-groove 52. At this time, the second optical fiber 60 is pressed into the V-groove 52 by the pressing piece 63 in order to prevent displacement. Therefore, the second optical fiber 60 is bent toward the pressing piece 63 with the portion near the tip in the V-groove 52 being aligned with the first optical fiber 50. .
The master head 61 is formed in a leaf spring shape as a whole, and has a structure capable of relaxing an excessive pressing force when accessing the array 51.
[0008]
[Problems to be solved by the invention]
By the way, the above-described master head 61 is repeatedly accessed to the array 51 in which the large number of first optical fiber wires 50 are arranged. That is, the second optical fiber 60 is bent each time it is accommodated in the V-groove 52. Therefore, the second optical fiber 60 may be broken, for example, when the second optical fiber 60 has external damage or internal strength deterioration.
[0009]
It is difficult to visually confirm the deterioration of the strength of the optical fiber, and in the past, a master head provided with a low-strength optical fiber was sometimes used for an optical switch. That is, the optical fiber of the master head may be broken during the operation of the optical switch, and it has been difficult to guarantee the reliability of the optical switch.

Therefore, the reliability of the optical fiber component can be inspected prior to mounting on the device.
[0016]
Further, it is desirable that the mounting section can mount a plurality of optical fiber components. By appropriately mounting a plurality of optical fiber components on the mounting portion, a strength test of the plurality of optical fiber components can be performed at the same time. Further, the strength test of a large number of optical fiber components can be efficiently performed by appropriately replacing the optical fiber components after the test.

Therefore, attachment and detachment of the optical fiber component can be easily performed, and workability can be improved.
[0018]
Further, it is desirable that the optical fiber component testing apparatus according to the present invention is provided with speed control means capable of adjusting the moving speed of the movable part.
According to the optical fiber component testing apparatus having such a configuration, the timing at which the contact member comes into contact with the removed portion of the optical fiber can be set to an optimal interval according to various optical fiber components. If the reciprocating motion speed is set as fast as possible, the test can be performed efficiently in a short time.
[0019]

[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of an optical fiber component test method and an optical fiber component test apparatus according to the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view showing a main body of the optical fiber component test apparatus according to the present invention, and FIG. 2 is a front view of FIG. FIG. 3 is a schematic diagram showing a state in which the movable unit of FIG. 1 reciprocates. FIG. 4 is a perspective view showing a controller connected to the main body of FIG.
[0024]
The optical fiber component test device of the present embodiment is a device for performing a strength test of an optical fiber provided in an optical fiber component.
This optical fiber component testing apparatus is characterized in that it has a mounting portion on which five optical fiber components can be mounted, and a movable portion that reciprocates with respect to the mounted optical fiber components. The movable portion is provided with a contact member that comes into contact with the optical fiber of the optical fiber component with the reciprocating motion.
Due to the reciprocating movement of the movable part, a contact state with the optical fiber is formed, and by alternately repeating the virtual connection state and the open state of the optical fiber, the optical fiber is repeatedly accessed when the optical fiber component is accessed to the array. Can be repeatedly subjected to bending stress.
Further, the optical fiber component testing apparatus is characterized in that it has a controller for controlling the posture of the movable part, the speed of the reciprocating movement, and the driving time.
[0025]
As shown in FIGS. 1 and 2, a main body 10 of the optical fiber component test apparatus according to the present embodiment has a main base 11 formed in a rectangular flat plate shape, and each member such as a mounting portion and a movable portion is provided. I have. The headset block 12, which is a mounting portion, has a substantially rectangular parallelepiped shape having a longer side slightly shorter than the longer side of the main base 11, and has ten screw holes 13 and ten positioning pins 14 on the upper surface thereof. They are provided side by side at intervals.
On the upper surface of the headset block 12, five master heads 1, which are optical fiber components, can be mounted at the same time and mounted in parallel. When the master head 1 is mounted, a screw is passed through a screw hole (not shown) of the master head 1 and the head set block 12 is Fix it in the hole 13.
[0026]
The array assumption base 16, which is a movable part, is a member provided to simulate an array in an FS type optical switch, and an array is provided for the optical fiber 3 of the master head 1 mounted on the headset block 12. And a bending stress equivalent to the bending stress applied when being stored in the V-groove.
[0027]
The array assumption base 16 is supported by a support plate 20 via a support shaft 21. The support plate 20 is provided at the edge of each short side of the main base 11 so as to rise vertically from the main base 11. The two support plates 20 are arranged facing each other with the headset block 12 and the array assumed base 16 interposed therebetween.
The array assumption base 16 is formed in a substantially rectangular flat plate shape having a long side substantially equal to the long side of the headset block 12. Support shafts 21 are connected to both sides in the longitudinal direction in a direction parallel to the headset block 12, and are supported at a position slightly lower than the upper surface of the headset block 12. The support shaft 21 is a shaft for rotating the array assumption base 16, and is provided such that the rotation shaft is located on the headset block 12 side.
[0028]
A V-shaped groove 16a for positioning the round bar 17 as a contact member is formed at a position on the upper surface of the array assumed base 16 opposite to the support shaft 21. The V-shaped groove 16a is formed in a direction orthogonal to the optical fiber of the master head 1 mounted on the headset block 12, and the round bar 17 is fitted and positioned in the V-shaped groove 16a. The round bar 17 protrudes upward from the V-shaped groove 16a, that is, toward the optical fiber 3 of the master head 1 in a state of being positioned in the V-shaped groove 16a. Further, the round bar 17 is fixed from above by fixing members 18 provided at two places on the upper surface of the array assumed base 16.
The round bar 17 is preferably processed into a smooth curved surface so as not to damage the optical fiber 3 when its surface comes into contact with the optical fiber 3. For example, SUS steel or polished steel may be used. It is formed as a material. The round bar 17 can be appropriately selected and used in an optimum size according to the shape of the optical fiber component mounted on the master head 1.
[0029]
A motor 25 for driving the array assumption base 16 is provided in a space below the array assumption base 16. The motor 25 is arranged so that its rotation axis is parallel to the rotation axis (support shaft 21) of the array assumed base 16, and is fixed by a motor bracket 26 provided on the main base 11. The motor 25 is connected to a controller described later, and is driven by electric power electrically controlled by the controller.
[0030]
An eccentric cam 27 is provided on the shaft of the motor 25. The eccentric cam 27 and the cam receiver 22 provided on the lower surface of the array assumed base 16 constitute an eccentric cam crank mechanism. This cam receiver 22 is preferably provided on the back side of the V-shaped groove 16a.
[0031]
When the motor 25 is driven, a force acts to rotate the eccentric cam 27 and periodically move the cam receiver 22 up and down. Therefore, by continuously driving the motor 25, the array assumption base 16 reciprocates up and down on the V-shaped groove 16a side with respect to the master head 1 around the support shaft 21 as a rotation axis.
[0032]
As shown in FIG. 3A, when the array assumed base 16 is lowered, the round bar 17 is separated from the optical fiber 3 of the master head 1. The optical fiber 3 at this time is in a state equivalent to the open state when the master head 1 is not accessing the array.
Here, the optical fiber 3 is a removed portion in which the resin coating is removed from the distal end portion of the optical fiber core wire 4 coated with resin, and a carbon fiber is formed around the optical fiber of the glass body constituting the core and the clad. Is a carbon-coated fiber (CCF) coated with a thin film. A pressing piece 2 for pressing the optical fiber 3 into the V-groove of the array is provided below the tip of the master head 1.
[0033]
As shown in FIG. 3B, when a force that pushes the cam receiver 22 upward from the eccentric cam 27 acts, the array assumption base 16 rotates about the support shaft 21 as a rotation axis, and the posture changes, and the round bar 17 moves. It comes into contact with the optical fiber 3 from below. When the round bar 17 is raised to the highest position, the round bar 17 presses the pressing piece 2 while bending the optical fiber 3. The optical fiber 3 at this time is in the same state as the connection state when the master head 1 accesses the array.
[0034]
As shown in FIG. 3, the rotation of the eccentric cam 27 causes the array assumed base 16 and the round bar 17 to reciprocate with respect to the master head 1 repeatedly. With this reciprocating movement, the round bar 17 can apply bending stress while repeatedly contacting the optical fiber 3.
At this time, the bending stress applied to the optical fiber 3 by one contact is set to be equal to the bending stress when the master head 1 accesses the array.
[0035]
As shown in FIGS. 1 and 2, a spring fitting 29 is mounted on the main base 11 below the cam receiver 22, and a cam is provided between the cam receiver 22 and the spring fitting 29. A tension spring 28 for pulling the receiver 22 toward the main base 11 is provided. The tension spring 28 keeps the cam receiver 22 so that the cam receiver 22 does not jump from the eccentric cam 27 when the motor 25 is driven at a high speed.
[0036]
The spring metal fitting 29 is provided with a counter switch 30. The counter switch 30 is a button-type switch, and is configured such that each time the counter projection 23 provided on the lower surface of the array assumption base 16 presses the button 31, an electric signal is sent to a controller described later. . That is, each time the array assumption base 16 performs one reciprocating motion, the counter switch 30 sends an electric signal to count the number of reciprocating motions.
[0037]
Further, the optical fiber component test apparatus of the present embodiment includes the controller 40 shown in FIG. The controller 40 is electrically connected to the motor 25 of the main body 10 and the switch 30 for the counter, and various switches and the like are provided on the front surface. The various switches include a power switch 41, a power LED 42, a start button 43, a position adjustment button 44, a speed gauge 45, a counter 46, and a timer 47.
[0038]
The main power supply of the controller 40 is switched on / off by a power switch 41. When the power is on, the power LED 42 is turned on, so that the state of the main power can be visually checked. The start button 43 is a switch for driving the above-described motor 25, whereby the applied voltage is turned on for a predetermined timer set time.
[0039]
The position adjustment button 44 is a position control means capable of finely adjusting the position of the array assumption base 16, and the voltage applied to the motor 25 is turned ON only when the button is pressed. The position adjustment button 44 allows the motor 25 to be driven for a short time at a time, and the array assumption base 16 can be displaced to a desired posture.
When the master head 1 is attached to or detached from the headset block 12, the position adjusting button 44 is pressed to lower the attitude of the array assumed base 16, whereby the optical fiber 3 of the master head 1 is inadvertently inserted into the round bar 17 or the array. The contact with the hypothetical base 16 can be prevented.
[0040]
The speed gauge 45 is a speed control means of a dial gauge for setting a rotation speed at which the motor 25 is driven. Specifically, the rotation driving speed of the motor 25 is adjusted by controlling the magnitude of the voltage applied to the motor 25. By using the speed gauge 45, the reciprocating speed of the array assumption base 16 can be adjusted, and the timing at which the round bar 17 contacts the optical fiber can be set to an optimum interval.
Further, by setting the reciprocating speed of the array assumption base 16 as fast as possible, a large number of contacts can be obtained in a short time, so that the test can be performed efficiently.
[0041]
The counter 46 is a means for reading the electric signal sent from the counter switch 30 described above and measuring the number of reciprocations of the reciprocating motion of the array assumption base 16. The number of times measured is displayed on the display plate 46a. When the reset switch 46b is pressed, the measured numerical value is reset.
The number of reciprocations of the reciprocating motion of the array assumption base 16 can be known by appropriately checking the number of measurements, so that the number of times of bending stress applied to the optical fiber 3 can be managed.
It should be noted that the counter 46 can have another function. For example, a function may be provided in which a desired target value is input in advance, and the supply of power to the motor 25 is automatically stopped when the number of measurements reaches the target value.
[0042]
The timer 47 is a means for measuring the time in conjunction with the start button 43 described above and stopping the driving of the motor 25 at an arbitrary time after the start of the test. The timer 47 sets a target continuous drive time in advance, and automatically stops the supply of power to the motor 25 when the drive time has elapsed.
Therefore, the test time of the strength test can be appropriately set, so that the strength test can be stopped in accordance with the time when the desired guaranteed access count required for the master head 1 has elapsed.
[0043]
Next, a test method of the optical fiber component of the present embodiment will be described.
First, the power switch 41 of the controller 40 shown in FIG. 4 is turned on, and it is confirmed that the power LED 42 is turned on. Then, by appropriately pressing the position adjustment button 44, the attitude of the array assumed base 16 of the main body 10 shown in FIGS. 1 and 2 is adjusted. Preferably, the round bar 17 is adjusted to be at the lowest position. By such adjustment, the workability when attaching the master head 1 to the headset block 12 is improved, and the optical fiber 3 of the master head 1 is inadvertently brought into contact with the array assumed base 16 and the round bar 17. This can prevent the optical fiber 3 from being damaged.
[0044]
Next, the master head 1 is mounted on the headset block 12 of the main body 10. At this time, up to five master heads 1 can be mounted in parallel. By mounting a plurality of master heads 1 at the same time, a large number of master heads 1 can be efficiently tested.
[0045]
In addition, the display 46a of the counter 46 is visually observed, and if the numerical value is not zero, the display is returned to zero by pressing the reset switch 46b.
Further, the driving speed of the motor 25 is set by the speed gauge 45. The setting of the speed gauge 45 may be appropriately performed during a test in which the motor 25 is driven. Further, when setting the driving time of the strength test, the timer 47 sets the continuous driving time.
[0046]
After completing the various settings, the start button 43 is pressed to drive the motor 25 to start the strength test of the master head 1.
When the motor 25 is driven, the round bar 16 reciprocates up and down by the rotation of the eccentric cam 27 as described above. At this time, the round bar 16 repeatedly contacts the optical fiber 3 with the reciprocating motion, and the same bending stress as when the master head 1 accesses the array can be repeatedly applied.
[0047]
The guaranteed number of times of applying a bending stress to the optical fiber 3 is, for example, 10,000 times.
When the continuous drive time is set by the timer 47, the drive of the motor 25 is automatically stopped when the start button 43 is first pressed and the set time is reached.
[0048]
When a plurality of master heads 1 are tested at the same time, when the optical fiber 3 of any one of the master heads 1 breaks during the test, the start of the motor 25 is stopped by appropriately pressing the start button 43, and the breakage is performed. It is possible to mount a new master head 1 in place of the master head 1 having the optical fiber strand 3 described above. Note that while the driving of the motor 25 is stopped, the time measurement of the timer 47 is automatically stopped. After the replacement of the master head 1, the strength test is performed by pressing the start button 43 again.
[0049]
When the strength test is completed, the master head 1 in which the optical fiber 3 is not broken can be determined as a reliable optical fiber component. By mounting only the optical fiber component having the guaranteed strength on a device such as an optical switch, the reliability of the device can be guaranteed.
[0050]
Further, in the optical fiber component test apparatus of the present embodiment, the configuration is such that the attitude of the array assumed base 16 fluctuates around the support shaft 21 and the round bar 17 reciprocates up and down. The test apparatus is not limited to this embodiment.
For example, it is also possible to adopt a mode in which the contact member is repeatedly brought into contact with the removed portion of the optical fiber by providing a slider crank mechanism in the movable portion and reciprocating up and down.
[0051]
Furthermore, although the contact member of the present embodiment uses the round bar 17, the contact surface that comes into contact with the optical fiber 3 may be a curved surface that is convex with respect to the optical fiber 3. Can be used. For example, the round bar 17 as a contact member may be formed integrally with the array assumed base 16.
[0052]

Therefore, an optical fiber component having a low-strength optical fiber can be detected, and only a reliable optical fiber component can be mounted on a device.
