Description
Technical Field
The present invention relates to the field of optical communications technologies, and in particular, to a method, an apparatus, a device, and a computer storage medium for detecting an optical fiber fault.
Background
The optical fiber communication backbone network is evolving towards large capacity and long distance. Compared with the common single-mode fiber G.652 fiber, the ultra-low loss large-effective area G.654.E fiber remarkably improves the electroless relay transmission distance, and is beneficial to the application of the ultra-100G coherent wavelength division technology in a backbone network. However, the test points and laboratory test results show that if the g.654.e fiber is disconnected and the g.652 fiber is used to connect two disconnection points, i.e., the g.654.e fiber and the g.652 fiber are fusion-spliced, the single-point fusion loss is too large, thereby limiting and offsetting the performance advantage of the g.654.e fiber. The existing backbone optical cable network mainly uses g.652 optical fiber, and has already tried to lay an optical cable link based on g.654.e optical fiber, so for the possible mixed fusion welding of g.654.e and g.652 optical fibers, it is necessary to find and modify in time.
The existing optical fiber loss testing method mainly comprises an optical power meter and an optical time domain reflectometer. The optical time domain reflectometer is a precision instrument manufactured based on the optical fiber Rayleigh scattering and Fresnel reflection principles, and is widely applied to optical cable construction and maintenance. The optical time domain reflectometer can simultaneously measure the loss of an optical fiber line and the fusion loss, and has high accuracy.
However, optical time domain reflectometry requires bi-directional testing of optical fibers. For backbone fiber networks, the 2 OA site spacing is typically around 80 km. If the same 1 optical time domain reflectometer is used, forward/reverse tests need to be respectively carried out at two ends of an optical fiber link, and the round-trip test distance and time of personnel are long. The instrument stores the bidirectional test data, extracts the bidirectional test data through software, and then obtains an actual loss value through manual sorting and analysis. Once the welding is unqualified, the welding needs to be returned to the site for construction, the labor cost is higher, and the service is influenced for a longer time.
Therefore, in the prior art, the efficiency of optical fiber fault detection is low.

Referring to fig. 1, fig. 1 is a flowchart of an optical fiber fault detection method according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
In this step, when detecting that the optical fiber to be detected has a fault, a forward loss value of a first event point and a forward loss value of a second event point are measured at one end of the optical fiber loop along a first direction of the optical fiber loop. Then, based on the forward loss value of the first event point and the forward loss value of the second event point, the forward loss value of the segmented optical fiber is determined, and the forward loss value of the segmented optical fiber between the first event point and the second event point is obtained.
The optical fiber loop is formed by using a first optical path where the fault point is located and a second optical path which is homologous and homoclinic with the first optical path. Specifically, in the embodiment of the present invention, the optical fiber loop is formed by: in the optical fiber to be detected, in an optical jumping station or an optical amplifier station adjacent to the fault point, a first optical path where the fault point is located and a second optical path which is homologous and homoclinic with the first optical path form an optical fiber loop in an optical fiber jumping connection mode.

As shown in connection with fig. 2, a fault occurs at point C, where point C may be referred to as a fault point. Then, with reference to fig. 2, the optical drop station or the optical add station adjacent to the point C forms an optical fiber loop by means of optical fiber splicing the first optical path C1 where the fault point is located and the second optical path C2 which is homologous and homoclinic with the first optical path. Wherein, the D terminal can be referred to as one terminal of the optical fiber loop. At this end, testing was performed using an Optical Time Domain Reflectometer (OTDR).

In this step, the reverse loss value of the first event point and the reverse loss value of the second event point are measured along a second direction of the optical fiber loop at the one end of the optical fiber loop. A reverse loss value for the segmented optical fiber is then determined based on the reverse loss value for the first event point and the reverse loss value for the second event point.

By searching the information, the optical fiber loss range corresponding to the optical fiber can be obtained.
Here, in order to obtain the measurement result by the tester, in the case where it is determined that the optical fiber misconnection exists, a first prompt message may be further output, including: measured values, information indicating the presence of a mixed fiber splice, and the like.
In the embodiment of the invention, when the optical fiber to be detected has a fault, the first event point and the second event point are respectively measured along the first direction and the second direction of the optical fiber loop at one end of the formed optical fiber loop, so that whether optical fiber misconnection occurs or not is determined according to the measured values. Therefore, by using the scheme of the embodiment of the invention, the measurement of the optical fiber can be completed at one end of the test without the need of a tester to go to and fro at the two ends of the test, thereby improving the efficiency of optical fiber fault detection.
On the basis of the above embodiment, the method may further include: and under the condition that the optical fiber mixed connection does not exist, determining whether the optical fiber fusion loss reaches the standard or not according to the forward loss value of the first event point, the forward loss value of the second event point, the reverse loss value of the first event point and the reverse loss value of the second event point.

And respectively carrying out forward/reverse tests on the other end of the optical path (the end which is not in jumping connection with other optical paths in the optical path where the fault point is located) by adopting an optical time domain reflectometer, so that the measurement of the loss of the optical fiber line and the fusion loss can be realized. Therefore, by using the scheme of the embodiment of the invention, a tester does not need to test the two ends of the optical path back and forth, so that the measuring time can be reduced, the welding loss value can be quickly given and the fiber mixing condition can be judged after the welding is finished in field construction, the rework efficiency is improved, the labor cost is reduced, and the service opening/recovery time is shortened.
Referring to fig. 2, first, forward (direction indicated by arrow in the figure)/reverse (direction indicated by arrow in the figure) tests are performed by an optical time domain reflectometer located at one end (end D in the figure) of the optical fiber, and the other end of the optical fiber is jumped by the optical fiber to form a loop.

And then comparing the obtained optical fiber loss value with the stored optical fiber loss range corresponding to the type of the laid optical fiber, and judging whether the optical fiber mixed melting problem exists or not. If the loss value of the optical fiber exceeds the stored loss range, the optical fiber to be spliced and the original laid optical fiber are different optical fibers, namely, the optical fibers are mixed and melted, and prompt and rework is carried out immediately. If the two-way test average value is in the stored optical fiber loss range, the continuous optical fiber and the original laid optical fiber are the same type of optical fiber, and whether the optical fiber fusion loss reaches the standard is further judged continuously. Comparing the loss value of the welding point with the stored fusion loss range of the optical fiber, and if the loss value is within the range, prompting that the optical fiber reaches the standard; if the range is exceeded, the condition that the product does not reach the standard is prompted, and the product is reworked immediately.

And then reading the stored range of the loss of the original laid optical fiber, and judging whether the bidirectional average value of the optical fiber loss between A and B belongs to the range of the loss of the original laid optical fiber. If not, the fusion spliced optical fiber and the original optical fiber are different types of optical fibers, the test value of the section of optical fiber and the loss range of the original laid optical fiber are displayed, and the mixed splicing of the optical fibers is prompted; if the fusion loss is consistent with the fusion loss, the situation of optical fiber mixed connection does not exist, and the stored range of fusion loss of the original laid optical fiber is continuously read.
And 405, judging whether the optical fiber welding loss reaches the standard.
It is determined whether or not the bidirectional average loss value at the event point A, B falls within the range of the fusion loss of the original laid optical fiber. If not, the welding does not reach the standard, the test value of the point and the range of the welding loss of the original laid optical fiber are displayed, and the welding is prompted to not reach the standard; if the fusion is up to standard, the test value of the point and the fusion loss range of the original laid optical fiber are displayed, and the fusion is prompted to reach the standard.
