Description

Technical Field

[0001] This utility model mainly relates to the field of optical fiber communication management system technology, specifically to an intelligent optical fiber matching system based on wireless networking and optical fiber macrobending loss. Background Technology

[0002] Optical communication ODF racks have numerous ports and complex interconnections, making data center management cumbersome and time-consuming. Due to historical reasons, issues such as misconnections, loose connections, and performance degradation frequently occur, resulting in significant resource waste. Traditional data center management for ODF interconnection matching involves sequentially connecting a red light source, injecting optical power, or introducing attenuation to each port of one ODF. At the other end of the ODF, each port is checked for red light leakage, detected optical signals, or changes in attenuation. If leakage, signal detection, or attenuation changes are detected, the matching relationship between the two ports is recorded. All matching processes are implemented manually in a single thread. Taking a 256x256 connection capacity as an example, an average of 16,448 fiber connection measurements are required. Assuming each measurement takes 10 seconds, this would require approximately one person's workload per week, resulting in low efficiency and a high error rate.

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] In data centers that have already been put into use, some fiber optic resources on the ODF racks are already carrying services. Manual testing may introduce the risk of causing long-term interruptions to existing services.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0035] See attached document Figure 1-5An intelligent optical fiber matching system based on wireless networking and optical fiber macrobending loss includes a dumb resource management platform 1 and two sets of data hosts 2. Each data host 2 is connected to a generator 3 and a detector 4. The generator 3 and detector 4 are connected to each other via ODF frame 1 5 and ODF frame 2 6, respectively. The generator 3 and detector 4 are connected to the data host 2 via communication module 1 7. The two sets of data hosts 2 are connected to the dumb resource management platform 1 via communication module 2 8. The generator 3 is connected to one ODF frame 1 5, while the other ODF frame 2 6 only requires detector 4 to be losslessly attached to the outer sheath of the optical fiber for arraying. Communication module 2 8 can be connected to the dumb resource management platform 1 using wired or wireless technology, enabling the dumb resource management platform 1 to schedule the operation of the generator 3 and detector 4, automatically discover optical fiber connection relationships, and report them.

[0036] See attached document Figure 2 The generator 3 includes a drive motor 301, an elastic fiber clamping slot 302, and a fixed stop post 303. An optical fiber is placed inside the elastic fiber clamping slot 302. The drive end of the drive motor 301 is positioned near the side of the elastic fiber clamping slot 302. When the drive motor 301 is not working, the optical fiber does not bend (state 1), and no external bending loss is introduced. When the drive motor 301 starts working, it presses the elastic fiber clamping slot 302 towards the fixed stop post 303. Under the combined action of the drive motor 301 and the fixed stop post 303, two macrobends are formed, causing light inside the optical fiber to leak through the bends, resulting in macrobend loss (state 2). Therefore, the generator 3 can control the magnitude of the bending loss inside the optical fiber by controlling the advance depth of the drive motor 301.

[0037] See attached document Figure 3 The detector 4 includes an optical path detection module 401 for detecting the analog quantity of the output voltage of the optical power and a battery module 402 for powering the device. The output terminal of the optical path detection module 401 is connected to a microcontroller module 403, and the output terminal of the microcontroller module 403 is connected to a LoRa RF module 404. The microcontroller module 403 is used to collect power and detect the output analog quantity. The measured data is transmitted to the repeater through the LoRa RF module 404 and reported.

[0038] See attached document Figure 4 In another embodiment, the overall design of detector 4 is further decomposed into different design modules, mainly as follows:

[0039] Optical module for non-intrusive fiber optic service pigtails: Since most service-side pigtails are primarily Φ3 pigtails with Φ2 pigtails as secondary, compatibility between the two types must be considered from the initial design stage. To avoid impacting service performance quality, the macro-bending loss of the fiber needs to be controlled below 1dB. Therefore, a detailed analysis of the macro-bending loss and bending radius of these two types of fibers is conducted. It is evident that smaller diameter fiber pigtails are more sensitive to insertion loss caused by bending. Therefore, according to the attached... Figure 4 The measured data shows that the bending diameter needs to be controlled above 14mm, which is a very important reference value.

[0040] See attached document Figure 5 The optical path detection module 401 includes photodetector 1 4011 and photodetector 2 4012. The upper end of photodetector 1 4011 and photodetector 2 4012 is provided with fiber bending slot 4013 for placing fiber optic pigtails. The fiber bending slot 4013 has a left signal channel 4014 and a right signal channel 4015, which are set corresponding to photodetector 1 4011 and photodetector 2 4012.

[0041] Reference attached to the bent portion of the optical path detection module 401. Figure 4 The structural design is as follows: The optical signal entering through the left signal channel 4014 is detected by both photodetector 4011 and photodetector 4012. According to the principle of tangential light leakage, the optical power of photodetector 4012 is greater than that of photodetector 4011. Similarly, the optical signal entering through the right signal channel 4015 is also detected by both photodetector 4011 and photodetector 4012. Again, according to the principle of tangential light leakage, the optical power of photodetector 4011 is greater than that of photodetector 4012. Therefore, based on the attached... Figure 5 The structural design can achieve two key indicators: first, to detect whether there is light in the optical fiber, and second, to detect the direction from which the light in the optical fiber comes.

[0042] In this embodiment, the networking scheme of detector 4 takes into account the low-power mode, and the main considerations are as follows:

[0043] 1. It adopts LoRa networking to achieve tens of thousands of IoT connections through low-power networking design and LoRa modules;

[0044] 2. Low-power business logic design with timed signal transmission mode to minimize power consumption;

[0045] 3. Powered by button batteries, designed to last 2-3 years;

[0046] 4. All end-side signals are uniformly collected into the LoRa gateway, and then connected to the upper-layer dumb resource management system through the northbound interface or the RESTful API interface. They can also be connected to the asset management system through a mobile APP.

[0047] 5. The Lora gateway has an open interface, which can also be directly connected to a customized mobile app.

[0048] In another embodiment, the networking scheme of detector 4 is not limited to LoRa networking. Wireless networking technologies can also be used, such as Bluetooth, Zigbee, NB, 5G IoT, 4G modules and 5G modules, WIFI, etc.

[0049] This technical solution uses a large-scale wireless network of generators and detectors as its foundation. The detectors detect the loss changes generated by the generators, and combined with the binding relationship between the detectors, generators, and ODF rack pigtail ports, a network management platform enables large-scale intelligent fiber-to-fiber matching. The large-scale fiber-to-fiber matching technology avoids service interruptions. The core of this intelligent fiber-to-fiber matching technology lies in its large scale and high efficiency. Utilizing a wireless network of detectors and a dumb resource management platform, in addition to enabling fiber-to-fiber matching within the data center, it also allows for 24 / 7 online monitoring of the service quality of key optical fibers within the data center. Furthermore, it can be linked with the digital transformation of data center optical fibers and ports. The generators and detectors serve not only as fiber-to-fiber matching tools but also as digital tags or part of the tags for optical fibers, thereby achieving the overall digital transformation of the ODF rack within the data center.

[0050] In summary, this can greatly simplify the workload of fiber locating between ODF racks. Taking a 256x256 connection as an example, the fiber locating time can be reduced to less than one hour, and it can also support long-term online monitoring of fiber performance.

[0051] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
