After years of construction, the backbone network of the power communication system has basically realized the transmission media optical fiberization, the service bearer network, operation monitoring and management automation and informationization. However, as the distribution network of backbone network access layer, due to many nodes, wide coverage and difficult construction, it has been lack of suitable communication technology and construction mode, which has become the bottleneck of the development of power communication network and restricted the development of intelligent distribution Electricity business applications. Distribution Communication Access Network is to achieve the basis of distribution automation, the pros and cons of its performance and reliability, the realization of distribution automation and operational reliability have a decisive influence. At present, there are many communication modes in the distribution automation communication network construction, such as Ethernet-based Passive Optical Network (EPON) technology, Power Line Carrier (PLC), wireless private network, wireless public network GPRS / CDMA / 3G and so on. Among them, optical fiber EPON communication technology has advantages in terms of security, reliability, real-time, high bandwidth and networking flexibility. With the maturity of Passive Optical Network (PON) technology, it is applied in pilot projects of domestic and foreign telecom operators' networks and smart grids to meet the requirements of intelligent distribution services for communication bandwidth and reliability. In the implementation of distribution network construction in urban areas, especially in the old urban area, the Optical Distribution Network (ODN) planning is the most important because of the complicated construction environment, long construction period and unpredictable conditions. One of the tricky things. A good ODN planning is the basis for the distribution and communication access network to facilitate the construction and maintenance. Therefore, it is an important precondition to implement distribution automation to plan a reasonable ODN optical distribution network. Problems in the traditional ODN optical distribution network ODN is one of the most important links in the construction of optical communication network. Compared with other active devices, ODN networks are more important, including optical fiber cables, optical connectors, optical splitters, and ancillary equipment for connecting and connecting these devices Most of the lines and devices are either buried deep or deployed in a building. In the event of a failure, maintenance is difficult and costly, even higher than the new cost. The traditional ODN network construction brings a large number of fiber optic patch cables and optical cables. Traditional paper labels rely on manual character recognition and manual entry, resulting in very low efficiency and high error rate. The fiber information with wrong label information is harder and harder to maintain and manage, which eventually turns into a "dead fiber", resulting in a continuous decrease in the utilization of optical fiber lines in the network. DSI Smart ODN technology With the construction of optical distribution network ODN, equipment manufacturers have been exploring solutions to these problems, including intelligent ODN and future more promising technical solutions. DSS Intelligent ODN network consists of intelligent optical distribution network management system, intelligent management terminal, intelligent optical distribution network equipment and intelligent optical devices composed of four parts. In the traditional fiber pigtail, patch fiber and splitters and other optical devices embedded in a tag, these optical devices will have the identity of information, has become a smart optical devices. When you plug these devices into a smart ODN device, you can read their identity information and manage it. At present, the main tagging technologies used by smart ODN manufacturers in China are contactless electronic tags, non-contact RFID tags and two-dimensional QR code tags. DSE's intelligent optical distribution network equipment includes intelligent optical fiber distribution frame, intelligent optical cable transfer boxes, smart optical fiber distribution boxes and other equipment. In addition to the traditional ODN functions, the intelligent ODN network device also has the functions of port management and communication, reads the tag information of intelligent optical devices inserted in each port and transmits the information to the intelligent network management system through the intelligent management terminal. DeSco's intelligent optical transfer box with a built-in RFID reader embedded RFID reader, RFID tags to identify the location of smart tags and tags, built-in optical fiber cable with a built-in port LED lights, intelligent instruction resource location and operation guidance. Intelligent will become the future development trend of ODN. Intelligent solution can improve the deployment and maintenance efficiency of ODN network. Passive network can also realize management and operation and maintenance. This will reduce the construction cost of the entire ODN network by 20% The cost is reduced by 50%. As the ODN network gradually becomes intelligent, it becomes the trend of the times.
