PON technology creates a future-oriented New Campus Network

In recent years, the trend of Industrial centralization has spawned a large number of parks, such as science parks and industrial parks. In addition, residential areas, shopping malls, schools, and so on are actually a park. People work, live, learn, and entertain in the park. As a necessary ancillary facility in the park, the communication network has gradually become an important standard for measuring the quality of the park. A fully functional, secure, and reliable campus communication network can greatly improve the quality of life and production efficiency in the campus. With the development of optical fiber communication technology, all-optical communication networks have become the first choice for campus network construction.

New Challenges of Campus Networks

Human beings have entered the era of knowledge economy with information technology as the core, and information resources have become equally important strategic resources as materials and energy; with its extensive penetration, intangible value, and unparalleled advancement, information technology is combined with traditional industries. The campus network is constantly enriched with business functions and application scenarios, and new businesses are continuously generated, traditional services are still widely used. Therefore, campus networks must be able to implement traditional IT and CT network functions at the same time; Be able to work stably in complex scenarios; on the other hand, IT is necessary to simplify the O & M of campus networks to quickly resolve faults, reduce the impact of network faults on users' production and life.

New services bring higher bandwidth requirements

In addition to basic network services such as voice and broadband, new services such as real-time video monitoring, HD video conferencing, wireless coverage, and IPTV are increasingly common in the campus, they put forward higher requirements for upstream and downstream bidirectional bandwidth of the campus access network.

Waste of resources on multiple networks is difficult to manage

Different businesses in the campus have different requirements on latency, bandwidth, and reliability. To avoid the mutual influence between different businesses, the campus network generally adopts multiple business networks. This network construction method not only wastes network equipment and manpower, but also increases the difficulty of campus network management.

Higher O & M challenges

The complexity of the network increases geometrically as the scale of the campus grows, and the difficulty of network O & M increases. If network faults cannot be detected and processed in a timely manner, in addition to greatly reducing the user experience on the network, it may directly affect people's daily production and life. This is a huge challenge to the network O & M capability of the campus.

All-optical Park Integrated Access Solution

PON is a point-to-point passive optical fiber network technology. It connects the local device OLT and the terminal device ONU through the ODN to achieve access to multiple services. In the process of finding a better campus network solution, we found that in large-scale access scenarios, no technology can take into account bandwidth capacity, network quality, and cost advantages like PON at the same time. The passive, economic, energy-saving, and easy-to-maintain features of PON are highly suited to the network requirements of enterprise parks and are increasingly favored by enterprise park users.

Based on years of accumulation in PON technology and campus networking, Huawei has launched an all-optical integrated access solution for the park, the solution provides unified access to multiple networks, including office, residential, production, and monitoring, and provides high-quality services such as broadband, voice, fax, and POS (Card swiping, it also has unique advantages in reliability and O & M.

Huawei all-optical Park Integrated Access Solution

Large Capacity and large bandwidth

The comprehensive access solution of Huawei all-optical Park fully considers the capacity and bandwidth requirements of all businesses in the park. A single OLT can support 196 PON ports and 16 k onu online at the same time, meeting the daily network usage of 100,000 people in the campus. In terms of bandwidth, the downstream bandwidth of a single PON port can reach 2.5 GB, and the bandwidth of a single OLT can be more than GB, making it easy to implement broadband access from GE to desktop. In addition, the OLT device can simultaneously provide PON, 10g pon, and 40g pon access, so that the park does not need to change the original network when the network needs to be resized, which is not only more convenient, it also protects network construction investment.

Uniform carrying of multiple services

In addition to the big bandwidth data service, this solution can also uniformly carry narrowband services such as analog speech, POS machines, and faxes. Through RFC2198 redundant audio protocol and 20 ms to 10 ms packaging, Huawei can ensure that the fax service is not interrupted 24 hours in the harsh network conditions with a packet loss rate of 1%, this makes traditional services carry better load than the original single network.

To address the differences between multiple services, Huawei's hierarchical QoS can precisely manage networks based on different requirements of latency, bandwidth, and reliability to optimize resource configuration. On the other hand, when multiple businesses are on the same network, they must be effectively isolated to eliminate security risks. In this regard, the all-optical Park can achieve full physical isolation from the OLT To The ONU, so that the production network and living network can be securely carried on a platform, you can also use VLANs to divide subnets in the same scenario in a more refined manner.

Through these efforts, the high-quality load of various campus network services on one network is guaranteed. It not only saves a lot of resources, but also makes management more centralized and convenient.

Easy deployment and O & M

The Huawei all-optical Park uses a passive optical fiber network, which is easy to deploy and reliable. However, PON is a time-division multiplexing-based communication protocol that has little impact on each other, making it easier to locate faults.

Moreover, through the N2510 optical line detection system, unified network management of U2000 network equipment, and Intelligent Optical Fiber solution iODN, Huawei has achieved ONU on-site deployment free of charge, and fast plug-and-play deployment; no matter which node has a problem, the entire network can be promptly detected, remotely monitored, and quickly restored, so that most network problems have not been perceived by users. Therefore, the O & M of the campus network becomes very simple and can be easily handled without professional Communication Technicians.

All-optical campus network has arrived

The Huawei all-optical Park Integrated Access solution provides the park with ultra-high-bandwidth access to adapt to the network development trend. It also provides a uniform network for new and old businesses to facilitate planning and management. Moreover, it is fast to deploy, simple O & M, truly matching the demands of campus users on the network. Now, this solution has been widely recognized, in China, the campus network of Changchun University, Beijing Communications Administration, Datong Coal Mine, Rizhao Port, and Tengchong Yunfeng Shan International Hot Spring health resort have recently selected this solution for network building. The tide of all-optical Park integrated access network construction has arrived.
