Description
Technical Field
The invention relates to the field of optical cable resource management, in particular to a resource management method and system for optical cable core pulling.
Background
With the increasing scale and complexity of networks, resource management software-based systems are increasingly widely used, but core pulling is not a conventional standardized method, and resource management software has not developed such a functional method. In operation, drawing type + labeling type is suitable for people to understand, modern resource management is more and more required to automatically process the optical resource and perform data analysis and scheduling calculation, and the optical resource is required to be dataized and structured. For the core pulling situation, no matter the EXCEL table, the data list of the resource management system or the system database is used, the existing recording method can not well describe the special situation, and a set of simple and effective methods is lacked.
A fiber optic cable has a fixed number of cores from a start point to an end point, that is, the fiber optic cable corresponds to the cores, and the cores are consistent with the start point to end point of the fiber optic cable. The method is an objective practical situation existing in all links of optical cable design, production, construction and use, and is a basic principle of optical cable resource management for decades. Thus, the most basic information describing a fiber optic cable includes "start-end point", "core count", and other attributes, as well as the principles underlying resource management software system development.

The construction method does not change the structure, trend and fiber core number of the original optical cable. Therefore, in the existing management method, the optical cable description record is not changed. That is, the description and recording modes of the same optical cable before and after the core pulling are unchanged, so that the recorded description contents of the same optical cable cannot be changed, but in practice, the number of fiber cores actually connected at the position of a skylight is reduced by a part, part of fiber cores are borrowed away, the existing method cannot reflect the actual connection condition of the optical cable, the core pulling is often represented by adopting a complex drawing and text description mode, the drawing operation relates to different personnel, departments and units, and the resource management accuracy, the effectiveness and the working efficiency are directly affected.
