A large-scale park generally refers to a company/unit/school within a fixed geographical area. It has a large coverage area and many buildings. It has relative independence and integrity in management, and generally has a certain perimeter. The network coverage is usually several kilometers, sometimes more than ten kilometers (when there are branches), and the fiber is connected. Generally, large-scale colleges, university towns, large enterprises, and high-grade hotels use such campus networks, generally above 10,000 information points, and usually have many buildings to achieve network coverage.
As the size of the network continues to increase, so does its application and complexity. For a large campus, there are usually many different companies/departments/groups that use the network at the same time, and the network carries a variety of complex applications. With the continuous increase in the number of network information points, the increasing number of users, the continuous emergence of various types of services, and the lack of network bandwidth, especially the lack of bandwidth in the core network has become a common phenomenon. Users have long consumed a large amount of network bandwidth in the network, FTP applications, online games, online video, etc., making traditional Gigabit networks unable to adapt to the needs of large campus networks. Based on the development status and trends of large-scale campus networks, we propose a 10G campus core network solution to address the growing bandwidth demand, business needs, network stability requirements, and capacity expansion and upgrade requirements to meet the cost-effective, high-yield network construction policy. .

Large campus core network cabling solution
The core network of the large campus is the lifeline of the network. In the past, only 20% of LAN communications reached the core network; most of the operations were done by personal computers, files were also saved and accessed locally, and file sharing was rare. However, today, the situation has undergone earth-shaking changes. It is estimated that 80% of all traffic needs to be transmitted through the core network. Today's applications take a centralized service, and users' files are stored on the server. File sharing and sharing are common. The multiplication of the demand for various types of network video applications and the enhancement of multimedia processing capabilities of personal computers have increased the burden on the core network. The core network must be able to handle this growing demand. Adopting a 10 Gigabit solution is the general trend.
The core network of the large campus must be able to provide high-speed data exchange and fast convergence of routes, requiring high reliability, stability, and scalability. A high-performance, highly reliable network structure must be provided. It is recommended to use a highly reliable ring network structure or a multi-device redundant mesh structure to build a core network platform for the integrated service.

"cross-connect" application
Save investment, reduce redundant construction, and reduce user input
Very flexible allocation and scheduling functions
Flexible network topology
Increased actual utilization of fiber
Quickly move, add, and replace. When moving, adding, and replacing, simply change the jumper between the patch panels, quickly recover, reduce misoperation, and ensure the normal operation of the device port.
