Description

[0002] Optical communication ODF racks have many ports and complex interconnections. The management of the computer room is cumbersome and time-consuming. Due to historical reasons, there are often misconnections, virtual connections, and performance degradation, resulting in obvious waste of resources. In traditional computer room management, the interconnection relationship between ODFs is matched by connecting a red light source or injecting optical power or introducing attenuation to each port of the ODF at one end, and then checking each port of the ODF at the other end to see if there is red light leakage, optical signal, or attenuation change. If there is red light leakage, optical signal, or attenuation change, the matching relationship between the two ports is recorded. All matching processes are implemented in a manual single-threaded manner. Taking 256x256 connection capacity as an example, an average of 16,448 fiber splicing measurements are required. Calculated at 10 seconds each time, it takes about one man-week of work to complete, which is inefficient and has a high error rate.

[0003] The inventor discovered the following defects during the operation of the specific embodiment: In the equipment room that has been delivered for use, some optical fiber resources on the ODF rack are already carrying services.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0021] Refer to the attached Figure 1-5 , an intelligent optical fiber matching system based on wireless networking and optical fiber macrobending loss, including a dumb resource management platform 1, two groups of data hosts 2, the data host 2 is connected with a generator 3 and a detector 4, the generator 3 and the detector 4 are connected through an ODF frame 1 5 and an ODF frame 2 6 respectively, the generator 3 and the detector 4 are connected to the data host 2 through a communication module 1 7, and the two groups of data hosts 2 are connected to the dumb resource management platform 1 through a communication module 2 8, wherein the generator 3 is connected to an ODF frame 1 5 on one side, and the detector 4 only needs to be non-destructively buckled on the outer skin of the optical fiber on the other side ODF frame 2 6 for arraying, and the communication module 2 8 can adopt wired or wireless technology to connect to the dumb resource management platform 1, so that the dumb resource management platform 1 can schedule the work of the generator 3 and the detector 4, and automatically discover the optical fiber connection relationship and report it.

[0022] Refer to the attached Figure 2 The generator 3 includes a driving motor 301, an elastic fiber clamping groove 302 and a fixed blocking column 303. An optical fiber is placed in the elastic fiber clamping groove 302. The driving end of the driving motor 301 is arranged close to one side of the elastic fiber clamping groove 302. The optical fiber is placed in the elastic fiber clamping groove 302. When the driving motor 301 is not working, the optical fiber does not bend, which is state 1, and no external bending loss is introduced; when the driving motor 301 starts to work, the elastic fiber clamping groove 302 is pressed to move forward in the direction of the fixed blocking column 303, and under the joint action of the fixed blocking column 303, two macro-bending curvatures are formed, so that the light in the optical fiber leaks through the bending, generating macro-bending loss, which is state 2; in this way, the generator 3 can control the magnitude of the bending loss in the optical fiber by controlling the advancement depth of the driving motor 301.

[0023] See attached Figure 3 The detector 4 includes an optical path detection module 401 for detecting the analog quantity of the optical power output voltage and a battery module 402 for powering the device. The output end of the optical path detection module 401 is connected to a single-chip computer module 403, and the output end of the single-chip computer module 403 is connected to a Lora radio frequency module 404, wherein the single-chip computer module 403 is used to collect electrical quantity to detect the output analog quantity, and the measured data is transmitted to the repeater through the Lora radio frequency module 404, and the data is reported.

[0024] See attached Figure 4 In another embodiment, the overall design of the detector 4 is further decomposed into different design modules, mainly as follows: Optical module of non-intrusive fiber optic service cursor: Since most of the service side pigtails are mainly Φ3 pigtails and supplemented by Φ2, the compatibility of the two pigtails must be considered at the beginning of the design. In order to not affect the service performance quality, the macro bending loss of the optical fiber needs to be controlled below 1dB. Therefore, a detailed analysis of the macro bending loss and bending radius of these two types of optical fibers is made. It can be seen that the smaller the diameter of the optical fiber pigtail, the more sensitive it is to the insertion loss caused by bending. Therefore, according to the attached Figure 4 The measured data requires that the bending diameter be controlled above 14 mm as a very important reference.

[0025] See attached Figure 5 The optical path detection module 401 includes a photodetector 1 4011 and a photodetector 2 4012. The upper ends of the photodetector 1 4011 and the photodetector 2 4012 are provided with a fiber bending slot 4013 for placing the optical fiber pigtail. The fiber bending slot 4013 has a left signal channel 4014 and a right signal channel 4015. The left signal channel 4014 and the right signal channel 4015 are provided corresponding to the photodetector 1 4011 and the photodetector 2 4012. The bending part of the optical path detection module 401 is shown in the attached Figure 4 The structure design is as follows: the optical signal entering the left signal channel 4014 is detected in both the photodetector 1 4011 and the photodetector 2 4012. According to the principle of light leakage from the tangential direction, the optical power of the photodetector 2 4012 is greater than the optical power of the photodetector 1 4011; the optical signal entering the right signal channel 4015 is detected in both the photodetector 1 4011 and the photodetector 2 4012. According to the principle of light leakage from the tangential direction, the optical power of the photodetector 1 4011 is greater than the optical power of the photodetector 2 4012; therefore, according to the attached Figure 5 The structural design can achieve two key indicators: one is to detect whether there is light in the optical fiber, and the other is to detect which direction the light in the optical fiber comes from.

[0026] In this embodiment, the networking scheme of the detector 4 takes into account the low power consumption mode, and the main considerations are as follows: 1. Adopt LoRa networking to achieve low-power networking design and LoRa modules to achieve IoT connections of tens of thousands of terminals; 2. Low-power business logic design and timed signal transmission mode to minimize power consumption; 3. Powered by button batteries, design goal: work for 2~3 years; 4. All end-side signals are collected uniformly by the Lora gateway, and then connected to the upper-layer dumb resource management and control system through the northbound interface or the Restful API interface, or connected to the asset management system through the mobile phone APP; 5. The Lora gateway has an open interface and can also be directly connected to a customized mobile phone APP.

[0027] In another embodiment, the networking solution of the detector 4 is not limited to Lora networking. Wireless networking technology can also use Bluetooth, Zigbee, NB, 5G Internet of Things, 4G module and 5G module, WIFI, etc.

[0028] In this technical solution, large-scale wireless networking of generators and detectors is used as the basis. The loss changes caused by the generator are detected by the detector. Combined with the binding relationship between the detector, the generator and the ODF rack pigtail port, the large-scale intelligent fiber-finding and fiber-matching functions are realized through the network management platform. The large-scale fiber-matching technology adopted avoids causing business interruptions. It has intelligent fiber-finding and fiber-matching technology, and the core point lies in scale and high efficiency. By using the wireless networking of detectors and the dumb resource management and control platform, in addition to realizing the fiber-finding and fiber-matching in the computer room, the service quality of key optical fibers in the computer room can also be monitored online for 24 hours a day. It can also be linked with the digital transformation of the optical fibers and ports in the computer room. The generator and detector are both fiber-matching tools and can be digital labels or part of the labels of the optical fibers, thereby realizing the digital transformation of the ODF racks in the entire computer room.

[0029] In summary, the workload of searching for fibers between ODF racks can be greatly simplified. Taking 256x256 connection as an example, the fiber searching time can be reduced to less than one hour, and the long-term online monitoring function of optical fiber performance can also be supported.

[0030] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
