Description

Technical Field

[0001] The invention belongs to the field of optical fiber communication networks, and in particular relates to a method for performing power loss analysis based on a hierarchical model. Background Art

[0002] Optical access network, referred to as OAN, is a communication network based on optical fiber communication technology that connects the backbone network to the end user. Compared with the traditional copper cable access method, the optical access network provides higher bandwidth, lower latency and more stable services. With the increasing demand for high-speed broadband access, optical access network has gradually become the mainstream implementation method of modern broadband access.

[0003] Although the optical fiber access network has significant technical advantages, it still faces many challenges in the implementation process of planning, design and management. For example, in the planning and design stage of the optical fiber access network, communication operators still rely mainly on manual drawing and the experience of professionals, and in the management stage of the optical fiber access network, they still rely mainly on traditional manual monitoring tools and manual analysis; such manpower-dominated methods lack the support of digital tools, which, on the one hand, makes the implementation process of the planning, design and management stages lack automation, and on the other hand, makes the information about each stage of the optical fiber access network life cycle scattered in different systems, forming independent "data islands". This makes the implementation process of the planning, design and management stages of the optical fiber access network time-consuming and complicated, and is prone to human errors, reducing efficiency. In particular, for the power loss analysis of the network nodes of the access network, relying on traditional manual analysis is prone to low accuracy and low efficiency; how to accurately implement the power loss analysis of network nodes without relying on the experience of professionals is an urgent problem to be solved. Therefore, in response to the above problems, this technical solution proposes a method for power loss analysis based on a hierarchical model. Summary of the invention

[0004] The present invention provides a method for power loss analysis based on a hierarchical model. This solution fully combines the full life cycle management of the optical fiber access network and the systematic coordination of various factors. It can efficiently and accurately realize the rapid analysis of the power loss of the network nodes of the access network without relying on the experience of professionals, greatly improving the efficiency of the power loss analysis of the network nodes of the access network, which is conducive to reducing the operation and maintenance costs. In summary, the problems in the background technology are solved.

[0012] S4, taking out the next optical fiber access network node in the node tree in the order of first root;

[0013] S5. According to each device included in the corresponding network node, use the model of each corresponding device to index and obtain the power loss of each device in the device database; and use the power loss of these devices as an independent variable to calculate the power loss of the corresponding network node itself;

[0014] S6. In conjunction with the parent node of the network node, query the path data in the optical fiber access network life cycle data, and calculate and accumulate the length of the cable connecting the network nodes in sections.

[0015] Then, query the optical fiber access network cable set data in the optical fiber access network life cycle data to obtain the model of the cable connecting the network node and the network node; index and obtain the unit length power loss of the cable of this model in the cable database; multiply the length of the cable and the unit length power loss of the cable to obtain the access cable power loss of the corresponding network node;

[0016] S7, adding the cumulative link power loss of the network node, the network node's own power loss and the access cable power loss to obtain the cumulative link power loss of the network node, and then returning to step S3;

[0017] S8. Summarize various forms of power loss of each optical fiber access network node; the various forms of power loss include calculation results of the own power loss, access cable power loss and link cumulative power loss, and output them.

[0018] Furthermore, the fiber access network life cycle management system is refined during the design phase, including adding more specific network topology details, node parameters, and cable types, making the data gradually accurate enough for deployment.

[0019] Furthermore, the fiber optic access network full life cycle management system refines the fiber optic access network life cycle data during the design phase; specifically, the system determines the equipment required to be included in each fiber optic access network node during the design phase, and determines the cables connecting the nodes and the specific wiring paths of the cables.
