Description
Technical field
The present invention relates to a kind of integrated optical fiber testing system, be meant a kind of integrated optical fiber testing system of testing at the optical fiber that extends from tested assembly particularly.
Background technology
In the field of optical communication, optical fiber is the assembly of normal use, in order to make the Optical Fiber Transmission can both normal running under various weathers and situation, therefore countries in the world have all been released relevant test optical fiber standard successively, the most normal being cited of test specification of U.S. Telcordia company wherein, its standard physical shock (Mechanical Shock), vibration (Vibration), thermal shock (ThermalShock), bending test (Flex Test), reverse test (Twist Test), layback test (SidePull Test), cable confining force test (Cable Retention Test) and winding permanance 8 test events such as (Mating Durability Test), and single test event has corresponding single test macro.
Bending is tested, is reversed test, layback test, the test of cable confining force etc. and is four kinds of more close test events of character, and its method of testing division is as follows:
See also Fig. 1, Fig. 1 is the equipment synoptic diagram of bending test, bending test macro 1 comprise rotatable 180 ° or ± 90 ° motor 10, it is a kind of reciprocating type rotary power unit (CyclicRotation Drive Unit), and drive tested assembly (not accompanying drawing), this tested assembly is extended with optical fiber 12, this motor 10 is provided with the rectifier coaxial with its axis of rotation (OffsetAdjustment) 101, this optical fiber 12 is connected in this fixed mount 11 and seizes on both sides by the arms on tool (not shown), the determining positions of this tool clamping the inflection point of optical fiber 12, because the inflection point must be the axis of rotation at motor, therefore adjust the bending central point of optical fiber 12 with this rectifier 101, optical fiber 12 is after the load elements 13 of 0.45 kilogram of 11 1 meters load of fixed distance frame, can make load elements 13 break away from support with the speed under load of standard, and drive this motor 10 and be rotated and monitor in real time at the transport property of optical fiber 12, to bend test.
See also Fig. 2, Fig. 2 can be to reverse test, layback test and wherein a kind of part synoptic diagram of cable confining force test.
Reversing test macro 2 is fixed on the clamping device 20 (Holding Fixture), and undermine optical fiber 21 for fear of clamping device 20, so elder generation's this optical fiber 21 of tackling 22 (strain relief) clamping by tightly being placed in optical fiber 21, at last optical fiber with respect to tackling 22 below the load elements 23 of 0.45 kilogram of distance load of 10 times of optical fiber 21 diameters, load elements 23 is broken away from the speed under load of standard rely on, and be that the axle center is respectively revolved to relative two directions and turn 90 degrees to reverse test with the center of this optical fiber 21.
This load elements 23 is adjusted into 0.45 kilogram and be positioned at 22～28 centimeters places that optical fiber 21 is started at for 22 times by tackling, optical fiber 21 is that nature is vertical, make optical fiber 21 90 ° of bendings then and continued for 5 seconds, and monitor the optical fiber output quality in real time, be finished until the standard monitoring period, promptly finish the layback test event.
This load elements 23 is adjusted into 0.45 kilogram and be positioned at 10 centimeters that Connectorized fiber optic cabling 21 is started at from end, and this load elements 23 broken away from according to the speed under load that drags is controlled at 400 microns of per seconds, do three tests continuously, can finish the cable confining force and test.
From above-described method of testing as can be known, enter four kinds of tests and must use four kinds of test macros respectively, even if wherein being arranged, three kinds of tests can share a kind of system because of character is approaching, also need two kinds of test macros to finish at least, the cost that not only expends equipment also increases operator's puzzlement, more causes the waste in space.
Moreover, after finishing a test, just tested assembly must be pulled down from system, be arranged at again in another system, caused great inconvenience and proofreaied and correct again to cause the tediously long of running time because of need.
Therefore, develop a kind of new test macro to integrate the problem of above-mentioned four kinds of test specifications for needing to be resolved hurrily now.
Summary of the invention
The integrated optical fiber testing system of four kinds of test events such as the shortcoming of prior art in view of the above, one object of the present invention are to provide a kind of and bend test, reverse test, layback test, the test of cable confining force is to save cost.
Another purpose of the present invention provides a kind of integrated optical fiber testing system, to save the space.
A further object of the present invention provides a kind of integrated optical fiber testing system, to save the running time.
For achieving the above object, the invention provides a kind of integrated optical fiber testing system, be used for being selected from bending (Flex), reversing (Twist), layback (Side Pull), reach wherein a kind of test of cable confining force (Cable retention) at the optical fiber that extends from tested assembly, this optical fiber testing system comprises: pedestal; Rotary power unit is arranged at this pedestal, is used to provide rotary power; Rotating body, in conjunction with and interlock in this rotary power unit, and have and be used to carry this tested assembly and can adjust the loading dish that angle is set; Bracing or strutting arrangement, having can be for the tumbler of this optical fiber lead of conversion, connect and place this optical fiber with the load adjustment part of adjusting load and be used to the hoistable platform accepting this load adjustment part and can adjust speed under load; Controller is arranged at this pedestal and is electrically connected at this rotary power unit, is used to control the rotary power that this rotary power unit output meets test specification.
