Brief Introduction to Optical Cable Construction of Access Network Technology

Currently, the access network technology is widely used, and the access network technology is also very commonly used. So I have studied the problems related to the access network technology construction planning and practical application. I will share with you here, I hope it will be useful to you. With the rapid development of broadband multimedia services and optical fiber communication technology, optical fiber communication technology has been more and more widely used in access network technology. In the past, the optical cable network mainly met the needs of transmission network construction, with fewer requirements for access layer optical cables. A small number of access layer optical cables are generally pulled directly from the aggregation node. With the rapid growth of Data optical fiber and user Optical Fiber demand in recent years, the number of construction of optical fiber cables at the access layer of telecom operators has also increased dramatically. How to build an access layer optical fiber network has become a topic widely discussed in the industry.

Construction Principles of access layer optical cables

According to the principle of network layering, we divide the domestic network cable into a relay layer and an access layer. The access layer optical cable refers to the optical fiber cable between the local bureau station and the user equipment terminal, the access layer optical cable is divided into trunk layer optical cable and wiring layer optical cable. Access Network Technology Optical Cable is the basic resource for key construction by telecom operators. In general, it should be organized and constructed in terms of network investment control, security, scalability, and clear structure.

1. moderately advanced and step-by-step implementation
In order to avoid repeated construction and investment, and quickly meet business development needs, we must adhere to the principle of moderately advanced construction during the construction process. At the same time, due to the complex and changing network environment of the access layer, the access technology is changing with each passing day. When the investment cost is fully considered, the planning of the access layer optical cable network should be strengthened according to market requirements and implemented step by step according to the planning.

2. hierarchical construction
According to the requirements of clear network structure, the access layer optical cable should be divided into trunk layer optical cable and wiring layer optical cable for construction. The trunk layer includes the trunk layer optical cable and optical junction node equipment, And the wiring layer includes optical cables, optical distribution nodes, and user terminal facilities. The construction of trunk layer optical fiber cables should be relatively stable according to the planning. The construction of trunk layer optical fiber cables should adapt to the characteristics of rapid market and technological changes. To meet these requirements and characteristics, hierarchical construction is required.

3. Topology Selection
The optical fiber access layer consists of three basic structures: Star, linear, and ring. In principle, the trunk layer optical cable adopts a ring topology, mainly because the business carried by the collection layer of the user's business access network technology must provide ring protection or dual-route protection. For non-intensive areas such as rural areas, if the optical cable routes do not meet the ring conditions, the trunk cable topology can be considered as not a ring.

Cables at the distribution layer are mainly subject to cost and route restrictions, making it difficult to establish a ring network. tree or star structure is often used. For some businesses that require high security, you can use a ring structure or dual-route protection. Based on factors such as user and business distribution, security requirements, and objective geographical conditions in the distribution area, multiple optical distribution points and single optical handover points can be flexibly deployed, or multiple optical distribution points through the topology of the Dual Optical Junction Point.

4. Optical handover device settings
Optical handover equipment refers to optical handover nodes and delivery distribution nodes that flexibly schedule and distribute the technical optical cables of the access network, the Setting principle mainly covers the management hole resources, business needs, user nature, and network security.

Determine the optical connection zone based on the management space resources, user attributes, and potential business needs. For example, if you choose to set up optical nodes in areas with high user density and rich pipe and hole resources, the optical fiber cables can be easily accessed and accessed to facilitate the construction of various optical cables.
