In the first year of the 14th Five-Year Plan for Education, relevant departments issued the "Guiding Opinions on Promoting the Construction of New Education Infrastructure and Building a High-Quality Education Support System", and basic networks became the focus of new infrastructure construction in colleges and universities. The document clearly proposed "upgrading campus networks": "promoting the upgrading of campus LANs", "realizing full coverage of campus wireless networks through Gigabit wireless LANs and other means", and "supporting the construction of campus Internet of Things", etc., which pointed out the direction for the development of colleges and universities during the 14th Five-Year Plan.

At present, in the process of promoting the development of new education infrastructure, colleges and universities are facing many challenges, such as increasingly high network requirements for teaching services, difficulty in network expansion, complexity of business launch brought about by multi-network integration, and difficulty in operation and maintenance.

First, there are more and more business terminals in classrooms and offices, which makes it difficult to connect/replace new equipment and expand the network. Currently, mobile phones, computers, large screens, recording/monitoring, electronic class signs and other terminals have increased massively, but due to insufficient interfaces in most university classrooms/offices, it is often necessary to re-pull network cables from the weak current room, which makes network expansion complex and makes it difficult to connect/replace new equipment.

Secondly, in the post-epidemic era, changes in teaching modes have made teaching services increasingly demanding in terms of bandwidth and latency. On the one hand, during the outbreak of the COVID-19 pandemic, remote modes such as cloud classrooms and cloud offices developed rapidly. On the other hand, more and more schools began to build smart classrooms, VR/AR classrooms, cloud training rooms and other types of classrooms, all of which require the network to have sufficient bandwidth and extremely low latency.

Thirdly, there are more and more smart terminals serving teachers and students, including not only teaching equipment such as laptops, smart phones, printers, and smart blackboards, but also terminal equipment such as electricity meters, water meters, and even air conditioners. How to ensure the safe and convenient access of so many terminal devices to the network and the unified management and control of network permissions? This has become the focus of smart campus construction.

Finally, as the business expanded, the number of connected networks and devices increased dramatically, but the number of professional operation and maintenance personnel did not increase exponentially, resulting in a bottleneck in network management.

So, how to build a high-bandwidth, easily expandable, and easy-to-operate and maintain campus network to meet the requirements of the 14th Five-Year Plan for Education?

The simplified Ethernet all-optical solution for colleges and universities integrates wired and wireless networks, has high bandwidth, is easy to expand, and is easy to maintain!

Ruijie's simplified Ethernet all-optical network solution for colleges and universities has the advantages of fiber access to rooms, elastic expansion, 100G to buildings, 10G to rooms, lightweight access, security management and control, plug-and-play, and intelligent operation and maintenance. It can greatly improve the network experience in scenarios such as teaching, office, dormitory, operation and maintenance in colleges and universities, and fully carry the next-generation campus network.

Fiber optic access to rooms, flexible expansion, 100G to buildings, 10G to rooms: With the minimalist Ethernet all-optical solution, optical fiber can be directly introduced into rooms, saving bridge space, providing local access to services and enabling flexible expansion. At the same time, because optical fiber has largely replaced the original copper wire, the bandwidth into rooms has been greatly improved, and the speed into rooms can reach 10G, meeting the high-bandwidth and low-latency requirements of multimedia classrooms, smart classrooms, VR/AR classrooms, cloud training rooms and other types of classrooms.

Lightweight access, secure management, plug-and-play, and intelligent operation and maintenance: Multi-rate switches installed indoors support registration-based online access, and only three steps are required to complete the device online, truly achieving zero-configuration access and plug-and-play. At the same time, in terms of operation and maintenance, the device supports link and optical attenuation detection, fault and loop detection, "allowing everyone to be a network manager."

It is worth mentioning that in dormitory scenarios where wireless is the main mode, Ruijie Ethernet All-Optical Network has also developed a unique low-voltage centralized power supply technology to provide centralized power supply for optical APs entering the room: 1 power supply module uses 4 square cables and is connected in series via a bus. It can provide power to 12 optical APs within a range of 200 meters, greatly saving bridge space and investment costs . The 56V DC power supply also effectively solves the problem of safe electricity use for students .

Nearly 150 universities have adopted Ruijie's simplified Ethernet all-optical network solution

At present, nearly 150 universities including China Pharmaceutical University, Huazhong University of Science and Technology, and Sichuan University of Science and Chemical Technology have adopted Ruijie's simplified Ethernet all-optical network solution and have expressed their approval!

China Pharmaceutical University has transformed the wired network in the teaching area, the wireless network in the teaching office building, and the outdoor wireless network in the stadium, square, main road and other areas into an all-optical network. The download speed can be more than 10 times that before the transformation, and the experience has been greatly upgraded. The number of weak-current rooms has been greatly reduced. The teaching area originally had 30 weak-current rooms , but now only one is maintained . SDN has been used to achieve zero-configuration online, reducing the workload of operation and maintenance personnel!

In the future, Ruijie 's simplified Ethernet all-optical solution will help more universities build high-quality campus networks and help the development of educational informatization to a higher level.
