Embodiment Construction

[0026] Such as figure 1 with figure 2 Shown, be the design method of optical fiber network structure of the present invention, be that the first level network structure is the center, by connecting a three-port basic network unit with internal intercommunication function on each of its edge nodes (see image 3 As shown), to achieve the purpose of outward expansion of the network structure, to realize the multiplication of the number of network edge nodes and the interconnection and intercommunication between all edge nodes, thus forming a second-level network structure. By analogy, if a basic network unit with three ports is connected to each edge node of the formed i-th level network, the outward radiation expansion of the network structure and the doubling of the number of network edge nodes can be realized. Form the i+1th level network structure. Wherein, i=1, 2, 3, 4, ..., M-1. Repeat this step until the formed Mth level network structure has the number of network edge...

Abstract

The invention provides a method for designing optical fiber network structure, and a structure capable of flexible extension. The method is characterized in that a first-level network structure is taken as a center; by connecting every edge node of the center with a three-port basic network unit with internal intercommunication function, the network structure is extended outwards to realize the multiplication of the number of the network edge nodes and the interconnection-intercommunication among all the edge nodes and to form a second-level network structure; and by analogy, every edge node of a formed i-level network continues to be connected with one basic network having three ports, so that the outward radiation-extension of the network structure and the multiplication of the number of the network edge nodes are realized so as to form an i+1 level network structure till the number of the network edge nodes of a formed M-level network structure meets design requirements. The network structure is characterized in reliability, high flexibility and extensibility, and has the advantages of low complexity, low cost and realization easiness.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication and communication network, in particular to a design method of a novel optical fiber communication network structure and a network structure which can be flexibly expanded. Background technique [0002] Optical fiber communication has the characteristics of large transmission bandwidth, low transmission loss and anti-electromagnetic interference, so it can be used to effectively support high-speed Internet, high-definition digital TV and cable TV services, digital voice services, distance education, digital libraries, telemedicine, Applications of e-commerce, intelligent transportation, data grid and large-scale multi-site distributed scientific computing, smart home network, industrial automation, etc. In addition, due to the advantages of small size, light weight and no electromagnetic radiation, optical fiber communication technology has important application value in vehicl...
