ODN is an FTTH optical cable network based on PON equipment, mainly to provide optical transmission channels between OLT and ONU. From the functional point of view, ODN can be divided into feeder optical cable subsystem, distribution optical cable subsystem, household line optical cable subsystem and optical fiber terminal subsystem from the central office to the user end. ODN mostly adopts P2MP topology, there are many connection nodes in the network, and network management is complicated. Optical fiber is more sensitive than copper wire and more easily damaged. Therefore, efficient construction, operation, and maintenance of ODN optical distribution network are essential, and a set of intelligent and accurate management solutions are required to ensure that the ODN network is fully utilized and effectively protect long-term investments.
The iODN solution can realize the automatic input and management of ODN optical fiber connection information, and ensure the accuracy and timeliness of the existing system information. At the same time, through the PDA's visualization software and the intelligent LED indication on the iODN device, automatic optical fiber search and precise operation can be realized, which greatly improves the efficiency of operation and maintenance, and realizes efficient operation and maintenance in the ODN network. In addition, based on the iODN architecture, various value-added applications can be developed on the basis of the inventory system to realize the automation of the whole process of construction, operation and maintenance.
The eODN (Easy ODN), based on GIS geographic information system and R intelligent identification system. The planning, design, construction and maintenance of the system’s ODN network cycle effectively combine the pre-planning, mid-term construction and post-maintenance, and use the non-contact intelligent system to improve the efficiency of optical fiber management, and realize the sharing of optical fiber information among various departments. Seamless transmission makes ODN network construction a dynamic virtuous circle and guarantees its sustainable development.
The complete solution of sODN (smart ODN) systematically considers the operation and maintenance characteristics of the existing traditional ODN, and strives to ensure that existing practitioners can easily adapt to the new ODN intelligent management mode in the intelligent implementation. The system has the characteristics of low power consumption, long life, and easy maintenance. Through new information technology, the ODN network becomes an organic whole to enhance customer perception.
