Importance: the business development of network, the telecommunication business under the new situation and new opportunities, to meet the advancement of 3 g network construction, the progress of building of FTTH, triple play construction gaining momentum, telecom business development situation is good, but for telecom enterprise, benefit is the absolute principle of development, that is to say, in this new situation, how to win the market, how to have a large number of users, got the upper hand in the market, it is the key. Limited for telecom enterprise, to build a solid foundation network, has the basis of abundant resources, that is, how to build a rich in resources, the network is stable and reliable network optical fiber physical network, it is need to thinking about telecom enterprises, and the light box in the local cable network construction will play a very important role, contribute to the expansion of the fiber optic cable construction and continue.
In the construction of the local cable network to improve the utilization efficiency of optical cable trunk, decrease The Times of the cable connector into open dial and effectively improve the safety and reliability of the cable, suggested to set up the necessary in fiber optic cable section of the fiber optic cable transfer box. The user side of the fiber optic cable transfer box cable, can according to customer demand for the development of each box, box capacity selection can give priority to with 288 core. Backbone fiber optic cable transfer box, should have access to the nearest base station (access layer node). In order to increase the flexibility of the access, part of the optical cable trunk fiber core can pick up on the tandem node layer.
There are two kinds of fiber optic cable in the construction of network mode: bus structure and loop structure. Line structure refers to from the bureau to the fiber optic cable transfer box only use a network structure of multi-cores cable connection, it is generally used in the business, not the scope of the key areas. Ring structure refers to all optical cable transfer box together using a multi-cores cable, optical cable fore and aft in the terminal, form a closed loop network structure, the distribution of fiber core and the structure of bus.
In short, light box in the application of the local cable network is important for the effective management of optical fiber core and reasonable planning use, improve the optical fiber core of fine management, at the same time make the construction of the optical fiber network flexibility and good scalability, better physical network cable service in the telecommunications business development and construction.
