Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber interconnection, in particular to a detection system for the polarity of a branch jumper. Background Art

[0002] Branch jumpers are usually due to inconsistent connector types at both ends or special polarity (line sequence), for example, MPO12 core is divided into 6 pairs of duplex LC products, and one MPO16 core is converted into 2 MPO8 cores with special line sequence products. For this type of product, the existing test method usually directly uses a polarity tester to measure the line sequence in the branch jumper. Specifically, the main end of the branch jumper to be tested is directly connected to the output end of the polarity tester, and the line sequence composed of multiple groups of channels (for example, in the MPO12 core is divided into 6 pairs of duplex LC products, the branch end is composed of 6 groups of channels The corresponding line sequence) is illuminated one by one by using the light-through technique, and then it is determined whether the line sequence (polarity) of the branch line to be tested is correct.

[0003] The method of measuring the line sequence of the branch jumper to be tested by lighting is inefficient. For different branch jumpers to be tested, even if the branch ends of the branch jumpers to be tested are composed of the same number of channels to form the corresponding line sequence, when the measurement object is changed, it is necessary to re-illuminate each group of channels in the branch end of the replaced branch jumper to be tested one by one to determine the polarity (line sequence) of the branch end of the replaced branch jumper to be tested. Batch copy detection is not possible. At the same time, due to lighting, it is impossible to customize the line sequence in the device, it cannot be recorded, and it does not have the product traceability function.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Embodiment 1:

[0034] The utility model embodiment provides a branch jumper polarity detection system, such as Figure 1 As shown, it includes a test box and a branch jumper to be tested; a standard branch jumper is arranged in the test box, the model of the standard branch jumper is the same as the model of the branch jumper to be tested, and the branch end of the standard branch jumper is connected to the branch end of the branch jumper to be tested, and the detection optical signal is input from the main end of the standard branch jumper and transmitted from the main end of the branch jumper to be tested, so as to detect the polarity of the branch jumper to be tested.

[0035] like Figure 1 As shown, the branch jumper polarity detection system of the embodiment of the utility model includes a test box and a branch jumper to be tested. A standard branch jumper is arranged in the test box. The model of the standard branch jumper is the same as the model of the branch jumper to be tested, and the branch end of the standard branch jumper is connected to the branch end of the branch jumper to be tested, so as to detect the polarity of the branch jumper to be tested through the standard branch jumper.

[0036] In order to better explain the detection process of the utility model, the following describes the polarity detection process of the branch jumper to be tested by the utility model with a specific model. Assume that the model of the standard branch jumper and the branch jumper to be tested in the embodiment of the utility model are both MPO12, and the MPO12 core is divided into 6 pairs of duplex LC products, that is, the branch end of the branch jumper with the model MPO12 is divided into 6 pairs of line sequences (polarity). Assume that the branch end of the branch jumper of MPO12 is divided into 6 pairs, namely the first pair, the second pair, the third pair, the fourth pair, the fifth pair and the sixth pair. The model of the standard branch jumper is the same as the model of the branch jumper to be tested. Assuming that the models of the standard branch jumper and the branch jumper to be tested are both MPO12, the branch end of the standard branch jumper is connected to the branch end of the branch jumper to be tested. Specifically, the first pair of branch ends of the standard branch jumper is connected to the first pair of branch ends of the branch jumper to be tested, the second pair of branch ends of the standard branch jumper is connected to the second pair of branch ends of the branch jumper to be tested,…, the sixth pair of branch ends of the standard branch jumper is connected to the sixth pair of branch ends of the branch jumper to be tested. When testing, the first pair of two cores, the second pair of two cores, the third pair of two cores, the fourth pair of two cores, the fifth pair of two cores and the sixth pair of two cores of the branch jumper to be tested are tested one by one (in the utility model, theoretically, the line sequence of the same serial number at the branch end of the standard branch jumper is the same as the line sequence of the same serial number at the branch end of the branch jumper to be tested. For example, the line sequence of branch end 1 of the standard branch jumper is theoretically the same as the line sequence of branch end 1 of the branch jumper to be tested). Taking the detection of the first pair as an example, assuming that there is a mismatch in the line sequence of the first pair of branch jumpers to be tested, the detection optical signal is input from the main end of the standard branch jumper to the first pair of standard branch jumpers, then input from the first pair of branch jumpers to be tested, and output from the main end of the branch jumper to be tested. When there is a mismatch in the first pair of branch jumpers to be tested (that is, the line sequence of the first pair of branch jumpers to be tested is different from that of the first pair of standard branch jumpers), the detection optical signal passes through the standard branch jumper and the first pair of branch jumpers to be tested respectively. An error signal will appear (i.e., the test fails), indicating that the first pair of branch jumpers to be tested has failed the polarity test; when the first pair of branch jumpers to be tested is correct (i.e., the line sequence of the first pair of branch jumpers to be tested is the same as the line sequence of the first pair of standard branch jumpers), the test passes when the detection optical signal passes the standard branch jumper and the first pair of branch jumpers to be tested respectively, indicating that the first pair of line polarity test of the branch jumpers to be tested has passed, i.e., the first pair of branch jumpers to be tested has the same line sequence as the first pair of standard branch jumpers. The utility model can measure the line sequence of the branch end of the branch jumper to be tested by measuring the line sequence of the branch end in the standard branch jumper and whether the detection optical signal has passed the test.

[0037] In order to make the detection of the polarity of the branch jumper wire of the embodiment of the utility model more universal, in a specific application scenario, the embodiment of the utility model manufactures a series of different test boxes (see Figure 5 and Figure 6 As shown, two different test boxes are represented). According to the model of the branch jumper to be tested, the corresponding test box is selected (in fact, a test box of the same model as the corresponding test box and the standard branch jumper is selected) for testing, and the line sequence of the branch end of the corresponding branch jumper to be tested is obtained through the line sequence of the branch end of the standard branch jumper. It is worth noting that the line sequence of the branch end of the standard branch jumper in the test box of the embodiment of the utility model is correct and known; in addition, the line sequence of the branch jumper in the embodiment of the utility model is the polarity of the branch jumper. When the embodiment of the utility model performs batch testing on the branch jumpers to be tested, the branch jumpers to be tested are first set in the detection system of the utility model, and the branch jumpers to be tested are tested. After the detection of the branch jumper to be tested is completed, the original branch jumper to be tested is removed, and a new branch jumper to be tested is replaced for measurement, thereby realizing batch testing of the branch jumpers to be tested.

[0038] In order to illustrate the complete solution of the embodiment of the utility model, the details of the embodiment of the utility model are described in detail below. In order to detect the polarity of the branch line end of the branch jumper to be tested, such as Figure 2 As shown, an embodiment of the utility model also includes a polarity tester; the optical output end of the polarity tester is connected to the main end of the standard branch jumper, the receiving end of the polarity tester is connected to the main end of the branch jumper to be tested, the output end of the polarity tester outputs a detection light signal, and the receiving end of the polarity tester receives the detection light signal, so as to measure the polarity of the branch jumper to be tested through the polarity tester.

[0039] The embodiment of the utility model sets a polarity tester, and connects the optical output end of the polarity tester to the main end of the standard branch jumper in the test box, so that the detection optical signal is transmitted to the standard branch jumper in the test box through the polarity tester; the receiving end of the polarity tester is connected to the main end of the branch jumper to be tested, so that the polarity of the branch jumper to be tested can be measured by the polarity tester. Specifically, the optical output end of the polarity tester outputs the detection optical signal, and transmits it from the main end of the standard branch jumper into the standard branch jumper, and then transmits it to the branch end of the branch jumper to be tested through the branch end of the standard branch jumper, and then transmits it to the polarity tester through the main end of the branch jumper to be tested, and the polarity of the branch end of the branch jumper to be tested is measured by the polarity tester.

[0040] In order to connect the optical output end of the polarity tester with the main end of the standard branch jumper, an embodiment of the utility model also includes a first guide jumper; one end of the first guide jumper is connected to the optical output end of the polarity tester, and the other end of the first guide jumper is connected to the main end of the standard branch jumper, so as to realize the connection between the optical output end of the polarity tester and the main end of the standard branch jumper.

[0041] In order to connect the optical receiving end of the polarity tester with the main end of the branch jumper to be tested, an embodiment of the utility model also includes a second guide jumper; one end of the second guide jumper is connected to the optical receiving end of the polarity tester, and the other end of the second guide jumper is connected to the main end of the branch jumper to be tested, so as to realize the connection between the optical receiving end of the polarity tester and the main end of the branch jumper to be tested.

[0042] The present utility model embodiment detects the polarity (line sequence) of the branch line end of the branch jumper to be tested one by one (as described above, and will not be repeated here). In order to detect the polarity of the branch line end of the branch jumper to be tested one by one, Figure 3 As shown, an optical switch is provided on the branch end of the standard branch jumper in the embodiment of the utility model. Taking MPO12 as an example, the branch end of the branch jumper to be tested has a line sequence consisting of the first pair, the second pair, the third pair, the fourth pair, the fifth pair and the sixth pair. First, the optical switch is used to control one core of the first pair of optical fibers to form a path (other lines are disconnected) so as to detect the polarity of one core corresponding to the first pair at the branch end of the branch jumper to be tested. Then, the optical switch is used to control the other core of the first pair of optical fibers to form a path (other lines are disconnected) so as to detect the polarity of the other core of the first pair. Then, the optical switch is used to control one core of the second pair of optical fibers to form a path (other lines are disconnected) so as to detect the polarity of one core corresponding to the second pair at the branch end of the branch jumper to be tested. Then, the optical switch is used to control the other core of the second pair of optical fibers to form a path (other lines are disconnected) so as to detect the polarity of the other core of the second pair. In the above manner, the detection of the first pair, the second pair, the third pair, the fourth pair, the fifth pair and the sixth pair at the branch end of the branch jumper to be tested is completed in sequence.

[0043] In order to form a detection system for the polarity of branch jumper wires in the embodiment of the utility model, as shown in FIG. Figure 4As shown, an embodiment of the utility model also includes a first adapter, a second adapter and a third adapter. Specifically: a first adapter is provided at one end of the test box, the other end of the first guide jumper is connected to one end of the first adapter, and the other end of the first adapter is connected to the main end of the standard branch jumper, so as to fix the main end of the standard branch jumper and the other end of the first guide jumper on the test box; at least two second adapters are provided at the other end of the test box, the branch end of the standard branch jumper is connected to one end of the second adapter, and the branch end of the branch jumper to be tested is connected to the other end of the second adapter, so as to fix the branch end of the standard branch jumper and the branch end of the branch jumper to be tested on the test box; and a third adapter is also included, one end of the third adapter is connected to the main end of the branch jumper to be tested, and the other end of the third adapter is connected to the other end of the second guide jumper, so as to fix the branch jumper to be tested and the second guide jumper together. The embodiment of the utility model connects the polarity tester, the standard branch jumper in the test box and the branch jumper to be tested together by setting the first adapter, the second adapter and the third adapter to form a line sequence for measuring the branch jumper to be tested.

[0044] In order to prevent the optical output end and the optical receiving end of the polarity tester from being damaged, which would render the polarity tester of the present invention unusable, the polarity tester of the present invention is provided with at least one spare optical output end (see Figure 2-Figure 4 As shown, when testing the polarity of the branch jumper to be tested, the first Figure 2-Figure 4 The light output terminal 1 is shown. Figure 2-Figure 4 The optical output terminals 2, 3 and 4 on the polarity tester can be used as spare optical output terminals); the polarity tester is provided with at least one spare optical receiving terminal (see Figure 2-Figure 4 As shown, when testing the polarity of the branch jumper to be tested, the first Figure 2-Figure 4 The optical receiving end 1 shown, Figure 2-Figure 4 The optical receiving end 2, optical receiving end 3 and optical receiving end 4 on the polarity tester can be used as spare optical receiving ends). When one of the optical output ends and optical receiving ends on the polarity tester is damaged, the spare optical output end and spare optical receiving end can ensure the normal operation of the polarity tester in the embodiment of the utility model.

[0045] The utility model has a simple setting. No matter how complex the line sequence of the branch line end of the branch jumper to be tested is, the line sequence of the branch line end of the branch jumper to be tested can be easily and quickly measured by correspondingly connecting the branch line end of the branch jumper to be tested with the branch line end of the standard branch jumper. During the test, batch testing can be performed, and the test process is simple and fast. In addition, it can be set in the tester, and the record is kept in the polarity tester, so it has traceability.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
