Intelligent ODN system

Abstract

The invention discloses an intelligent ODN system comprising an SDH/MSTP backbone network. The SDH/MSTP backbone network is connected with an EPON professional network manager and an OLT optical line terminal. The EPON professional network manager is connected with an intelligent ODN network manager by means of northbound interface integration. The OLT optical line terminal is connected with an intelligent ODF through an optical cable. The intelligent ODF is connected with an intelligent transfer box through an optical cable. The intelligent transfer box is connected with an intelligent fiber distribution box through an optical cable. The intelligent fiber distribution box is connected with an ONU optical network unit through an optical splitter. The intelligent ODN is compatible with the existing EPON network hardware and integrated with the network manager, and thus, the existing equipment investment is protected to the maximum. Functions like resource allocation, construction guidance, status callback and topology construction are completed. Under the condition that the business process and the way of construction are not changed, unified management, unified process and unified scheduling are provided for the ODN network to realize automatic ODN operation and management. The system has obvious economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of power system cable wiring, and in particular relates to an intelligent ODN system. Background technique [0002] With the acceleration of the construction of "Broadband China", the large-scale construction of optical fiber broadband is unstoppable, and the construction of optical fiber basic networks is in full swing in various provinces and cities across the country. The management and maintenance problems brought about by ODN are becoming more and more prominent. The proposal of intelligent ODN will help to comprehensively solve the problem of massive optical fiber management caused by the large-scale construction of optical fiber infrastructure network. The so-called smart ODN is based on the electronic label technology, and uses electronic labels to identify various passive resources such as optical fibers, ports, and racks of the ODN, so that it has a unique identity in the network and accepts the sc...

AI Technical Summary

Problems solved by technology

[0003] The traditional ODN network is a passive network. Each node device is a dumb resource. There is no frame format definition for transmitting services, no overhead byte definition for network management, and it cannot terminate service signals transmitted by optical fibers. No management and maintenance features

Therefore, the traditional ODN only has simple and primitive management and maintenance measures. ODN management and maintenance all rely on manual work, which has problems such as low efficiency and error-prone. The performance includes the following aspects:

[0004] (1) Management is difficult. The passive network is still a "black box" and it is difficult to manage intuitively. During the construction process, it is faced with frequent searches and fiber jumping tasks

[0005] (2) Manual errors are large, and the accuracy of manual operation records is low, only 70%-90%

The network construction and maintenance stage requires a lot of manual entry and maintenance resource management, mainly in the construction of a large number of optical fiber distribution equipment and optical cables. This has brought great trouble to business operations

[0006] (3) Port resources are difficult to manage and maintain. Because a large number of manual resource entry procedures are used, and paper labels are used for the port identification of optical fiber distribution equipment, a large number of optical fiber resource information input errors, waste of port resources, and complex business operations are caused.
