Description

Technical Field

[0001] The present invention belongs to the field of information and communication technologies, and in particular relates to a method for monitoring the operation of communication optical fibers. Background Art

[0002] As the basic resource supporting optical fiber communication, optical cables are widely laid in urban pipelines and pipe galleries. Their operation and maintenance environment is complex, the coverage distance is wide, the types of carried services and applications are numerous, the network connection methods are complicated, and there is generally no power supply environment. It brings extremely difficult and huge challenges to the daily installation, operation and maintenance, optical fiber resources, management and scheduling of optical fiber cables as information transmission media. With the acceleration of the construction of power grid digitization and intelligence, the requirements for the transmission quality, reliability, maintainability and timeliness of optical fiber network systems are getting higher and higher.

[0003] The tag labels used in traditional optical cable information rely on manual entry, which is not only time-consuming and laborious with low efficiency, but may also cause inaccurate input of optical cable resource information, and it is impossible to obtain updated information or status parameters of the online working conditions of optical cables from this label in a timely manner. Moreover, after long-term use, this type of label is prone to aging and falling off, and cannot be reused.

[0004] In response to the problems of optical cable resource status, label management, etc. faced by the daily operation and maintenance of optical cables, many research institutions and well-known companies at home and abroad have proposed relevant technical solutions. For example, the 34th Research Institute of China Electronics Technology Group Corporation has upgraded a traditional OTDR instrument to an optical cable fault tracker, which uses the principle of optical cable birefringence to continuously shorten the search distance for optical cable fault points, so as to determine the location of optical cable fault points. In actual applications of this product, two aspects of personnel need to cooperate with each other, and the optical cable needs to be swung within a certain space. Since the optical cable line has been fixed in a specified position during optical cable construction, it is very difficult to swing it within a certain range at any position, causing many difficulties in use.

[0005] In related foreign research fields, the United States, Japan and some Western European countries have also invested a lot of manpower and experience in researching optical fiber sensor technologies and have achieved some breakthroughs in related aspects. Standard Telecommunication Company in the UK, Thomson Company in France and Siemens Company in Germany have all launched their own related products in the research and application fields of optical cable sensors. However, due to the relatively new product technology, the price of the product in the market cannot be accepted by the public for the time being, thus restricting its wide application in the industry.

[0024] In order to enable those skilled in the relevant technical field to better understand and implement this patent, the specific implementation manners will be further described in detail below in conjunction with the accompanying drawings of the specification. Embodiment

[0025] Please refer to Figures 1 to 5A communication optical fiber operation monitoring method is used in a communication optical cable system, wherein the communication optical cable system includes: a communication optical cable, an ODF distribution frame, an optical cable terminal box, and an optical cross-connection box; the characteristic is that: the communication optical cable system also has an active optical fiber channel ink screen label, and the active optical fiber channel ink screen label includes: an optical fiber channel label module, a reading and writing device, and an application management system; the active optical fiber channel ink screen label is movably connected to the optical fiber port of the unused optical fiber jumper of the ODF distribution frame, the optical cable terminal box, and the optical cross-connection box; the reading and writing device is handheld or rack-mounted.

[0026] The above-mentioned method for monitoring the operation of a communication optical fiber is characterized in that the fiber channel label module is of FC type, C type, ST type or LC type.

[0027] The above-mentioned communication optical fiber operation monitoring method is characterized in that the optical fiber channel label module is an optical fiber channel remote label (sending end label, receiving end label, transfer label and bidirectional label) module and an optical fiber channel local end label module.

[0028] The above-mentioned method for monitoring the operation of a communication optical fiber is characterized in that the optical fiber channel remote tag module is powered by an internal solid-state battery or an optical fiber battery, can work for a long time with low power consumption, and is in an optical monitoring sleep state most of the time. The module displays the results of the last detection or communication reception.

[0029] When the remote Fibre Channel label module connected to the remote ODF port is in sleep mode, it is called a sleep label module. It is awakened after receiving an optical signal, and then directly communicates with the Fibre Channel label module at the other end of the channel and measures the optical channel loss. It then goes back to sleep after displaying the information.

[0030] Because it uses electronic ink display technology, only very low power is required to maintain the display for a long time.

[0031] The remote Fibre Channel tag module, referred to as the wake-up tag module, is mounted under the ODF port that can be operated by operation and maintenance personnel. The wake-up tag module can be connected to the remote tag module through the button on the tag module or with a handheld reader / writer device to activate this tag and complete a new round of communication and detection process with the remote tag. In the final stage, the tag is refreshed and displayed.

[0032] The detection and communication process between the remote tag module can also be achieved by using a rack-mounted reader to trigger the local tag module at a fixed time.

[0033] The above-mentioned method for monitoring the operation of a communication optical fiber is characterized in that the label includes: label number: label category: light source power: label attenuation: marking time: correction code, a total of 20 bytes.

[0034] A method for monitoring the operation of a communication optical fiber, characterized in that the label number includes: station number, rack number, sub-rack number, and port number, a total of 8 bytes.

[0035] For example: FF.FF.FF.FF (starting number) > FF.FF.FF.FF (ending number), and another example: 12.23.34.45 > 23.34.45.56

[0036] A method for monitoring the operation of a communication optical fiber, characterized in that the label category includes: information such as identifying the optical fiber type, wavelength, and wavelength division, a total of 2 bytes; such as FFFF 1310nm.

[0037] A method for monitoring the operation of a communication optical fiber, characterized in that the label light source power represents the transmitting end label power, a total of 2 bytes; such as: FF.FF - 05.00 dBm

[0038] A method for monitoring the operation of a communication optical fiber, characterized in that the label attenuation represents the receiving end label loss, a total of 2 bytes; such as FF.FF: 10.00 dB

[0042] A method for monitoring the operation of a communication optical fiber, characterized in that in the communication optical cable system, the label optical power measurement range is: -5 to -55 dBm, the wake-up optical power > -40 dBm, the communication optical power > -45 dBm, the marking times > 1000 times, the continuous working time of the remote label module > 5 years, and the label interval < 2 seconds.

[0043] A method for monitoring the operation of a communication optical fiber, characterized in that in the communication optical cable system, the label operating temperature is: -10 to 70 °C, the sleep temperature range is: -30 to 80 °C, the operating humidity range is: 5% to 95%, and the mean time between failures > 50000 h.

[0044] See Figure 3, The active optical fiber channel label module is installed on the ODF frame. The active optical fiber channel label module can also be called AOL. The micro-power consumption ability of AOL enables it to work continuously for 5 years without charging, supporting more than 1000 optical fiber channel detections and communication processes. It supports wake-up methods such as low-light signal, manual button, and handheld charger charging. It supports optical signal transceiver and detection under long distance and large attenuation.

[0045] See Figure 4 , The active optical fiber channel label reading and writing handheld device can scan the QR code displayed in the label through the handheld device, and can also charge the label, trigger detection, read the content of proximal and distal labels, etc. by connecting to the interface at the tail end of the label through a wire.

[0046] See Figure 5 , The rack-mounted automatic update optical fiber label module supports up to 8 optical fiber label modules, and can also be used in combination with an optical switch board to complete regular and timely inspections of multiple optical fiber channel labels.

[0047] In this application, compared with traditional optical communication, the low-light and low-speed optical fiber communication technology can work at an extremely high transimpedance to achieve communication technology under low light. Compared with traditional optical communication, even if the received optical power is reduced by 30 dB, it can balance the contradiction between the channel bandwidth and the communication distance expectation, and the communication rate is reduced by 1000 times at the same time. In this way, communication can be carried out in a fiber optic system with such a large attenuation that ordinary optical communication cannot, and the attenuation of the optical fiber channel can be warned.

[0048] After the damaged optical fiber is damaged, the received optical fiber may only be -60 dBm, but it can wake up the dormant and distal modules from low power consumption and promote the communication, measurement, and detection processes to be realized in milliseconds.

[0049] The electronic ink screen technology is used to display the results of the previous measurement and communication, so that the measurement process and information of both parties in the communication can be stored in the form of visible electronic labels for a long time.

[0050] The optical fiber cable detection data acquisition is to achieve measurement, communication, and data acquisition on the SFP optical module, and batch wake up the AOL modules installed on the remote cross-connect box.

Press the top button on one tag, and the corresponding information can be received and displayed at the other end, showing the position of the tag corresponding to the test point at the other end.

[0054] (3)Display of optical cable operation and maintenance service information: The electronic tag uses a low-power ink screen and communicates with the ink screen through a handheld device to edit various contents such as the information of the optical cable label and service information. Later, the operation and maintenance personnel can activate the tag at any time to view the recorded information.

[0055] In this application, it can also be used for the monitoring application from the local end to the remote end, and the usage scenarios include: optical fiber distribution box, optical cable joint box, etc.; the main methods are as follows:

[0056] (1)Whether the optical cable is available: Measure the routing status corresponding to the port through the optical power meter built in the tag, and judge whether the optical cable is available according to the optical power value.

When using the optical power measurement function on one tag, the corresponding information can be received and displayed at the other end, showing the position of the tag corresponding to the test point at the other end.

Later, the operation and maintenance personnel can activate the tag at any time to view the recorded information on it.

[0059] (4)Operation and maintenance management: According to the actions of the operation and maintenance personnel operating the electronic tag, the network management system displays the information of the operated electronic tag, including time, location, and service information.

[0060] The main innovation points of this application are as follows:
