1.Operation status of optical fiber communication networkWith the continuous development of social economy and the popularization of optical fiber communication technology, subway communication network has gradually adopted optical fiber communication instead of traditional communication methods. Optical fiber communication has the characteristics of high speed, stability and reliability, and is a frequently used communication method in today's communication network. However, there are certain defects in the operation of optical fiber communication network. In the process of laying optical cables today, due to the influence of the line's own planning, many industrial communication networks and III communication networks are often mixed, which seriously affects the operation quality of optical fiber communication network. Insufficient optical cable core, this kind of problem mostly occurs in some hub stations of power system. In the case of continuous transformation of some hub stations, the remaining fiber core of the optical fiber channel cable will also be insufficient, especially in the process of large-scale data communication, which will affect the accuracy of communication data. The construction and renovation of optical cables are not thorough enough. With the rapid development of optical fiber communication technology, many optical cables will also be involved in construction and renovation. However, during the construction and renovation process, due to the limitation of line power outage, the construction of optical cable projects will also be subject to certain restrictions, resulting in incomplete construction and renovation of optical cable communication channels. A large amount of optical cable maintenance work is involved in the later operation, which seriously affects the operation efficiency of optical cables.
2.Optimization of optical fiber communication networkMany problems of optical fiber communication network seriously affect the efficiency of optical fiber communication and fail to give full play to the role of optical fiber communication. Therefore, it is necessary to reasonably optimize the optical fiber communication network and thoroughly improve the phenomenon that the hierarchical division of optical fiber communication network is not clear, the optical cable core is insufficient, and the construction and renovation of optical cables are not thorough enough. For the optimization of optical fiber communication network, it is mainly to build the second plane of optical fiber communication transmission, or even more network communication layer architecture, so as to improve the stability, effectiveness and reliability of optical fiber communication network.2.1 Optimization principles of optical fiber communication networkThe communication system is the key to the operation of the system. At the current stage, the main communication network used in the system is the optical fiber communication network. In the process of optimizing the optical fiber communication network, we must adhere to the optimization principles of communication flexibility, reliability, organization, and automation. The optical fiber communication network not only undertakes the function of information transmission and exchange, but also has high requirements for the capacity, reliability, and security of the communication network. In order to ensure that the optimization of the optical fiber communication network meets the corresponding requirements, the ring and grid optimization methods can be adopted to make the optical fiber communication network form such a communication shape. Combined with the current intelligent optical fiber network communication technology, it can ensure that the communication reliability of the ring and grid shape is higher. At the same time, according to the optimization of the optical fiber communication network, scientific analysis of business traffic and business flow should be carried out, and the structure and organization of the optical fiber communication network should be optimized. In addition, the transmission optical fiber selected in the optimization process should ensure that the corresponding capacity requirements are met, and there should be investigation and analysis of future development trends and market information. Try to leave a certain capacity for optical fiber communication to facilitate the expansion of later communication business.2.2 Optimization strategy of optical fiber communication networkOptimization of optical fiber communication network should not only formulate reasonable optimization scheme in theory, but also take into account the actual optimization situation. If the optical fiber line is re-laid in order to improve the security, reliability and transmission volume of optical fiber communication network, it will inevitably generate a lot of workload, which will not only waste a lot of manpower, material and financial resources, but also consume a lot of time. Moreover, the results after laying cannot guarantee to meet the requirements of the current optical fiber communication network. In addition, the business types are too concentrated. Obviously, re-laying optical cables is an undesirable optimization measure. The optimization of optical fiber communication network should not only be based on the optimization principles of reliability and security, but also abide by the optimization principle of simplicity. The staff can optimize the original optical fiber communication network. For example, the original optical fiber line can be recombined: the operation form of the communication network can be changed, etc. These are all effective strategies that can achieve the purpose of optimizing the optical fiber communication network without effort. In addition, due to the continuous increase in electricity demand and electricity consumption, the optimized optical fiber communication network must ensure a certain topology to facilitate the next communication network improvement. According to the current social development form and electricity demand, the optical fiber communication network should be properly optimized.2.3 Construction of the second plane of the optical fiber communication networkOptimization of optical fiber communication network is mainly applicable to places where optical fiber technology is applied but its functions are not fully utilized. When building the second plane of the optical fiber communication network, it is necessary to first select some sites where lines in the communication system are concentrated and the corresponding services, and then build the second plane transmission platform for these determined sites and apply the corresponding transmission equipment. In the process of construction, the medium and long-term development should be the main construction goal, which should be determined according to the actual development of the power system. It is necessary to ensure that the newly built second plane of communication transmission should have a line capacity of 10G, so as to ensure the reliability and efficiency of the optical fiber communication network.2.4 Use the second plane to share the communication loadWith the reform of the system, the amount of data and communication volume has gradually increased, and the communication load of the original optical fiber communication network has also increased, seriously affecting the communication efficiency of the optical fiber communication network. After the construction of the second plane in the previous part, the second plane of transmission can be used to share the actual communication load. It can be combined with the ring network site of the communication system, and then some sites can be connected to the second plane of transmission to achieve the role of load sharing. In addition, the second plane of transmission can also provide some backup services for related services, effectively reduce the phenomenon of data service terminals guided by single point errors, and improve the effectiveness of the optical fiber communication network.2.5 Determine the development direction of the second plane of transmissionFor the optimization of today's optical fiber communication network, the construction of the second plane of transmission is the main focus. With the gradual increase of communication services, the second plane of transmission should not only share the transmission burden of communication data, but also develop towards the sites of various communication services in the system, and gradually form the core position of site communication. The development direction of the second transmission plane is mainly to cooperate with the specific electricity consumption of power users in the power system, collect the electricity consumption of users, and improve the operation efficiency of the optical fiber communication network according to the level of the optical fiber communication network, and gradually develop towards the three-layer architecture of the regional local communication network, so as to comprehensively improve the operation quality of the optical fiber communication network and achieve the good development of the subway industry.2.6 Expansion of optical fiber communication networkWith the continuous development of social economy and the continuous expansion of communication systems, optical fiber communication networks should also be continuously expanded. In the process of building new subway lines, if conditions permit, geographic optical cables, overhead optical cables and other communication lines can be set up between some key stations. In addition, the laying of optical cables should be different from the optical cable routing of OPGW lines to improve the stability and reliability of optical cable communication.
3. Analysis of the operation and maintenance of optical fiber communication networks3.1 Unified management of intelligent networksThrough the operation and maintenance of optical fiber communication networks, comprehensive and unified intelligent management can be implemented on intelligent networks to ensure that the maintenance of optical fiber communication networks is more comprehensive, convenient and fast. The characteristics of intelligent network unified management system mainly include simple operation, convenient testing, performance statistics, network operation analysis and early warning, friendly interface, business configuration, fault query, fault analysis and location, etc. Once a fault occurs in the optical fiber communication network, the system can promptly alarm, conduct a comprehensive analysis of the operation parameters of the optical fiber communication network, quickly locate the fault of the optical fiber communication network, and dispatch staff to repair it in time to improve the reliability of the operation of the optical fiber communication network. In addition, the intelligent management system of the optical fiber communication network can also predict the potential network risks in the optical fiber communication network through the comprehensive analysis ability of the system, and effectively avoid potential risk factors.3.2 Formulate an operation and maintenance work planThe operation and maintenance of the optical fiber communication network requires the formulation of a reasonable operation and maintenance work plan, mainly based on the specific situation of the phased inspection report of the common optical fiber communication network, formulate a daily maintenance plan for the optical fiber communication network, and strengthen the maintenance of some areas prone to faults, try to avoid or reduce the faults that occur during the operation of the optical fiber communication network, and reduce the fault losses during the operation of the optical fiber communication network.3.3 Upgrade spare parts and accessories of optical fiber communication network on demandDuring the continuous maintenance of optical fiber communication network, there are still some problems that spare parts and accessories on old optical fiber communication lines have not been effectively maintained. These spare parts and accessories have aged after long-term use, which can easily cause optical fiber communication network failures. Therefore, according to the needs of optical fiber communication network, spare parts and accessories should be upgraded in stages, and spare parts and accessories should be continuously improved to avoid failures caused by aging and improve the stability of optical fiber communication network operation.3.4 Utilize the equipment service hotline opened by the manufacturerThe operation and maintenance of optical fiber communication network should also make full use of the equipment service hotline opened by the manufacturer. Once there is a problem with the optical fiber communication network, faster and more effective assistance and support can be obtained through the online service hotline, and the fault of the optical fiber communication network can be located in time, and remote assistance measures can be taken to handle the faults in the optical fiber communication network in time, effectively improving the reliability of the optical fiber communication network and reducing the losses caused by the failure.
The optical fiber communication network plays a key role in the development and operation of the subway. Especially with the rapid development of intelligent systems, data information communication becomes more important. In the past, there were some drawbacks in the optical fiber communication network that would have a certain impact on the communication quality. Therefore, the optical fiber communication network should be optimized to ensure the reliability of data transmission in the optical fiber communication network.
