Description

Background
In metro transport networks, optical fiber cable networks are an important infrastructure network. Due to the special properties of fiber optic networks, a bare fiber optic path is often made up of multiple jumper segments (within a building or optical cross-connect). In the process of splicing, whether the two ends of the fiber core of the optical fiber in the optical cable are matched or not needs to be tested, namely whether the fiber core of the optical fiber is correct or not and whether the attenuation of the fiber core is normal or not are verified.
In the process of implementing the embodiment of the present invention, the inventors found that: the following two methods are mainly used to test whether the two ends of the fiber core of the optical fiber are matched. 1. One constructor inserts a light emitting port of light source equipment into a fiber core port of a jumper optical fiber to be used in a front-end machine room, and simultaneously, the other constructor tests the receiving optical power at the corresponding fiber core port position in a jumper point machine room or an optical cross internal optical power meter, so that the test of optical fiber matching is realized. 2. One constructor tests the core of each Optical fiber segment to be used with a jumper Optical fiber by OTDR (Optical Time Domain Reflectometer) equipment. However, in the actual fiber jumping operation, due to lack of personnel, only one constructor can be arranged to perform the fiber jumping operation. In addition, although the OTDR device can find most problems of excessive core attenuation in time, it cannot find abnormal connection condition of the fiber end, and even the interruption condition of the optical cable segment out of the local point, so the accuracy of this method is low.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
In metro transport networks, optical fiber cable networks are an important infrastructure network. Due to the special properties of optical cable networks, a bare optical fiber path is often made up of multiple segments of optical cable segments that are jumped together. In which a length of fiber optic cable typically encloses a plurality of optical fibers. However, the optical fibers in the optical cable may have problems of disorder in sequence or fiber breakage, which may cause the core of the optical fiber to be incorrect, or the core of the optical fiber to be attenuated abnormally, thereby affecting the information transmission after the information is jumped. Therefore, in the process of performing the jumper connection, it is necessary to verify whether the core of the optical fiber is correct and whether the core attenuation is normal, that is, to perform the optical fiber matching detection.
Referring to fig. 1, which shows a schematic diagram of optical fiber jumper connection in an embodiment of the present invention, two ends of an optical fiber are usually located in two different machine rooms, and the distance between the machine rooms is long, so that an existing optical fiber matching test method usually needs two constructors to respectively complete the machine rooms at the two ends of the optical fiber. Specifically, one constructor inserts a light emitting port of the light source device into a fiber core port of the jumper optical fiber to be used in a front machine room, and notifies another constructor located in the jumper machine room of an inserted fiber core port serial number after the insertion is completed. When another constructor receives the notice, the optical power meter is used for testing the receiving optical power at the position of the fiber core port with the corresponding serial number, and whether the two ends of the optical fiber are matched or not is judged according to the size of the receiving optical power. Or, a constructor may use the OTDR device to test the core of each optical cable segment to which the jumper optical fiber is to be used, thereby completing the optical fiber matching test. However, in the actual fiber jumping operation, due to lack of personnel, only one constructor can be arranged to perform the fiber jumping operation. In addition, although the OTDR device can find most problems of excessive core attenuation in time, it cannot find abnormal connection condition of the fiber end, and even the interruption condition of the optical cable segment out of the local point, so the accuracy of this method is low. Therefore, the embodiment of the invention provides an optical fiber matching test system, which can complete matching test by only one constructor and has high accuracy of test results.
The following describes embodiments of the present invention with reference to the drawings.
Referring to fig. 2 and fig. 3, fig. 2 shows a schematic diagram of connection relationships among all elements in an optical fiber matching test system according to an embodiment of the present invention, and fig. 3 shows a schematic diagram of an operation of the optical fiber matching test system according to the embodiment of the present invention.

The optical fiber matching tester 30 starts to supply light to one end of the optical fiber core after receiving the light source switching instruction, and returns a result of starting to emit light to the intelligent terminal 10 through the cloud server 20. At this time, after receiving the information of starting to emit light, the constructor can turn on the optical power meter 40 to detect the received optical power at the other end of the fiber core, thereby determining whether the two ends of the optical fiber are matched. When the detection is completed, the constructor may operate the intelligent terminal 10 to transmit a light source switching instruction indicating turning off the light emission to the optical fiber matching tester 30 through the cloud server 20, so that the optical fiber matching tester stops emitting light, and the optical fiber matching test is ended.

Then, the microcontroller controls the light source driving module 33 to start or stop lighting the optical fiber by analyzing the information of starting or stopping lighting in the light source switch instruction. Meanwhile, the microcontroller returns the turn-on and turn-off results of the light source driving module 33 to the communication module 31, and the communication module 31 sends the turn-on and turn-off results of the light source driving module 33 to the intelligent terminal 10 through the cloud server 20.

After the intelligent terminal 10 receives the result of turning off the light source driving module 33, the intelligent terminal 10 may also send a turn-off instruction to the optical power meter 40 to turn off the optical power meter 40, and then the detection is finished.
According to the embodiment of the invention, the optical power meter 40 is in communication connection with the intelligent terminal 10, so that the intelligent terminal 10 can automatically control the opening and closing of the optical power meter 40 without manual opening or closing by constructors, the automation degree of the whole matching detection is enhanced, and the matching detection efficiency is improved.
In other embodiments, the optical power meter 40 may further send the detected received optical power to the intelligent terminal 10 through the communication connection with the intelligent terminal 10, so that the intelligent terminal 10 determines whether the two ends of the optical fiber core are matched according to the received optical power detected by the optical power meter 40.

Further, the smart terminal 10 may further include a storage module 13, which may store the received optical power and the final matching test result for subsequent analysis of the probability of optical fiber matching or for other subsequent work.
The optical fiber matching test system 100 of the embodiment of the invention comprises a cloud server 20, an optical fiber matching tester 30 and an optical power meter 40, wherein the optical fiber matching tester 30 comprises a communication module 31, a microprocessor 32 and a light source driving module 33, the light source driving module 33 is connected to one end of an optical fiber core, and the intelligent terminal 10 and the optical power meter 40 are located at the other end of the optical fiber core.

Meanwhile, when the intelligent terminal 10 receives the information that the light source driving module 33 is turned on, the constructor can access the optical power meter 40 to the other end of the fiber core of the optical fiber, and can verify whether the two ends of the fiber core of the optical fiber are matched or not through the detected received optical power. Compared with the prior art, the embodiment of the invention can complete the matching test of the optical fiber by arranging the optical fiber matching tester 30 at one end of the optical fiber core in advance and operating the intelligent terminal 10 and the optical power meter 40 at the other end of the optical fiber core by one constructor. This method requires fewer constructors and also results are accurate.

step S101: the cloud server receives a light source switch instruction sent by an intelligent terminal and sends the light source switch instruction to the optical fiber matching tester.
In this step, the light source switching command includes information indicating turning on and off of light emission.
Step S102: and the communication module of the optical fiber matching tester receives the light source switch instruction and sends the light source switch instruction to the microprocessor of the optical fiber matching tester.
Because the distance between the optical fiber matching tester and the intelligent terminal is long, the light source switching instruction cannot be directly transmitted through a wireless signal, and therefore the light source switching instruction needs to be indirectly transmitted through the cloud server.
Step S103: and the microprocessor controls the light source driving module of the optical fiber matching tester to be turned on and off according to the light source switching instruction, wherein the light source driving module supplies light to one end of the fiber core of the optical fiber when being turned on.

Step S105: the communication module sends the opening and closing results of the light source driving module to the intelligent terminal through the cloud server, wherein the optical power meter detects the receiving optical power of the other end of the optical fiber core when the light source driving module is opened.
The microprocessor can analyze information which represents the light-on and light-off in the light source switch instruction, controls the light source driving module to be turned on and turned off according to the analyzed result, and returns the turning-on and turning-off result of the light source driving module to the intelligent terminal through the cloud server. When the light source driving module is started, the light source driving module supplies light to one end of the fiber core of the optical fiber. Meanwhile, the constructor receives the opening result of the light source driving module at the intelligent terminal, and can access the optical power meter to the other end of the optical fiber core to detect the receiving optical power of the optical power meter, namely the received power of the light emitted by the light source driving module. By analyzing the received optical power, whether the two ends of the optical fiber are matched can be judged.
In some embodiments, the light source driving module includes at least 2 light emitting elements, and the wavelengths of the light emitted by each of the light emitting elements are different. Meanwhile, the light source switch command further includes information indicating a serial number of the light emitting assembly, and at this time, step S104 specifically includes: and the microprocessor controls a light-emitting component in the light source driving module to start or stop emitting light according to the light source switching instruction.

According to the information, the microprocessor can control the light-emitting components corresponding to the serial numbers in the light source driving module and the light source switch instruction to be switched on and off.
In other embodiments, the optical power meter is in communication connection with the intelligent terminal, and at this time, in step S105, the method specifically performs the following operations:
the communication module sends the opening and closing results of the light source driving module to the intelligent terminal through the cloud server, so that the intelligent terminal controls the opening and closing of the optical power meter according to the opening and closing results of the light source driving module.
After the intelligent terminal receives the opening and closing results of the light source driving module, corresponding opening or closing instructions can be generated according to the results, the instructions are sent to the optical power meter through communication modes such as Bluetooth or WIFI, and the optical power meter can complete corresponding opening or closing operations according to the instructions.
In the embodiment of the invention, the intelligent terminal sends a corresponding opening or closing instruction to the optical power meter according to the opening and closing result of the light source driving module, so that the optical power meter can finish corresponding operation. Compared with the embodiment, the optical power meter is not required to be manually turned on or turned off by constructors, the automation degree is higher, and the efficiency of the optical fiber matching test can be improved.

step S106: and the optical power meter sends the detected received optical power to the intelligent terminal, so that the intelligent terminal determines whether the two ends of the optical fiber core are matched or not according to the detected received optical power.
After the optical power meter starts to detect the received optical power, the detected received optical power is sent to the intelligent terminal, and then the intelligent terminal determines whether the problems of fiber core errors or abnormal fiber core attenuation and the like exist according to the size and the change rule of the received optical power; if so, determining that the two ends of the optical fiber are not matched; and if not, determining that the two ends of the optical fiber are matched.
In the embodiment of the invention, the intelligent terminal firstly sends the light source switching instruction to the cloud server, then the cloud server sends the received light source switching instruction to the microprocessor through the communication module, the microprocessor controls the light source driving module to be switched on and switched off according to the light source switching instruction, and the structure for switching on and switching off the light source driving module is returned to the intelligent terminal through the communication module and the cloud server. When the light source driving module is started, the light source driving module supplies light to one end of the fiber core of the optical fiber. Meanwhile, when the intelligent terminal receives the information of starting the light source driving module, a constructor can access the optical power meter to the other end of the fiber core of the optical fiber, and whether the two ends of the fiber core of the optical fiber are matched or not can be verified through the detected received optical power. Compared with the prior art, the embodiment of the invention can complete the matching test of the optical fiber by arranging the optical fiber matching tester at one end of the optical fiber core in advance and operating the intelligent terminal and the optical power meter at the other end of the optical fiber core by one constructor. This method requires fewer constructors and also results are accurate.
