Background
With the rapid increase of the access network on the service bandwidth requirement, the development of the optical communication technology and the reduction of the cost, the optical fiber communication becomes an important mode for the construction of an access network, namely, the optical fiber enters and exits, the optical nodes gradually move downwards, and the optical fiber arrives at a residence, an optical fiber arrives at a building, an optical fiber arrives at an office and an optical fiber arrives at a home, so that the inevitable trend of the development of the access network is realized.
The PON technology is a point-to-multipoint transmission technology, and data Terminal equipment connected to a trunk is called an Optical Line Terminal (OLT), and data Terminal equipment connected to branches is called an Optical Network Unit (ONU). The OLT is typically placed on the service provider side and the ONUs are typically placed on the customer side. The OLT and the ONUs are connected by an ODN (Optical Distribution Network), and the ODN adopts 1-level or 2-level light splitting according to the distance between a user and a machine room and the Distribution of the user.
Due to the characteristics of the PON network, any port of an ONU connected to the optical splitter can work. For example, an optical splitter has 8 ports, 1,2, 3.. 8, and the optical splitter is connected to 8 ONUs, a, B.. H subscribers, respectively, and it is possible for these subscribers to interchange ports or use an unused port. Which port of the splitter the user corresponds to is typically recorded in the resource management system.
With the implementation of the strategy of 'four-wheel drive' in china mobile, the home customer service is rapidly developed, but the Network resources of a PON (Passive Optical Network) installed in an actual installation site may not be accurate enough, thereby affecting the installation maintenance efficiency and customer satisfaction. Therefore, in order to improve the consistency rate of the theoretical connection and the actual connection of the home broadband resources in the system and ensure the accuracy of the field resources, the port resources connected to the home broadband field need to be checked to confirm the actual resource connection condition in the field.
