Light up the smart campus with a minimalist architecture, allowing every classroom to have a futuristic teaching experience!

In a bright music classroom at a certain middle school, first grade students are staring intently at the high-definition screen in front of the podium. The music teacher lightly tapped the touch screen, and a piano performance video of "My Motherland" played smoothly. The entire teaching process flows smoothly without any network lag.

This teaching scenario has now become a daily routine in 81 schools in a certain county. The efficient operation of these "digital classrooms" is supported by the newly fully established Smart Optical Education Network. With the support of all-optical networks, it is quietly reshaping the ecological pattern of county-level education and promoting high-quality development of education.

Demand driven: Campus network upgrade faces three major challenges

In 2025, a county will launch a comprehensive education digital upgrading project. As an important measure to improve the quality of education in the county, Smart Lite On follows the construction principle of high standard planning and step-by-step implementation to better meet the digital teaching needs of 81 schools and 1323 classes in the county, further optimize the allocation of educational resources, and promote the high-quality and balanced development of compulsory education in the county.

In order to provide strong network support for numerous smart campus scenario applications, many schools in this county need to meet the following requirements in campus network construction:

Connect the metropolitan area network and establish an education dedicated network. To achieve deep integration between the Education Bureau and the campus networks of various schools, in order to ensure seamless integration between the video conferencing systems of each school and the County Education Bureau.

Transforming traditional networks into all-optical network architectures. Implement network isolation between school office network and class network. And by simplifying wiring and reducing equipment, fiber deployment can be efficiently completed while saving costs.

Strengthen the ability of audio and video linkage, support multi scenario teaching and security management. It can achieve functions such as visualized online course tours, visualized educational broadcasting, and campus broadcasting.

Solution breakthrough: Three major breakthroughs achieved in all-optical network architecture

Based on the above project requirements, Smart Optics has chosen a dedicated all-optical campus networking solution, which covers all campus scenarios through the construction of one network, including education network, campus network, and public area network. This comprehensive solution has achieved the following breakthroughs in network construction:

Firstly, a high bandwidth architecture is adopted to construct an education private network. Smart Guangxun fully utilizes the full coverage advantage of the operation mall's domain network and has built a dedicated network channel for the education system through VLAN virtual partitioning technology. Moreover, adopting a multi-level bandwidth configuration, providing intelligent bandwidth selection from 10G to 200G, fully meeting the differentiated needs of education networks and campus networks for large bandwidth services.

Secondly, a passive PON architecture is adopted to achieve full coverage of the campus network. The all-optical transmission link realizes the full process optical network transmission from the core to the access end, and the comprehensive network coverage supports various businesses such as teaching, office, Internet of Things, and security in schools. Deploy multi service dual band cloud APs in low-density indoor areas such as classrooms and offices. Through graded deployment of gigabit to campus and 100Mbps to class, it ensures high-speed connection of intelligent terminal devices and comprehensive coverage of teaching scenarios. Innovatively integrating SOS alarm columns, intelligent broadcasting, and video surveillance systems in the public areas of the campus, building a comprehensive campus security linkage mechanism.

Thirdly, establish a digital teaching and security system that integrates audio and video. By deploying an audio and video linkage system, visual events in public areas can be quickly responded to, effectively preventing campus violence. In teaching scenarios, support visual online course patrols to enable principals and grade managers to conduct remote classroom supervision; The educational broadcasting system has visual control capabilities, which can automatically broadcast preset voice when detecting classroom violations, abnormal examination rooms, and other situations, assisting teachers in remote management and effectively maintaining a harmonious and efficient teaching order.

More importantly, this solution supports smooth evolution from 10G to 200G, with no bandwidth restrictions on fiber optic media, extending optical terminals to every application scenario, significantly reducing the difficulty of end deployment, and laying a solid foundation for the development of educational informatization in a certain county in the next 30 years.

Value Highlighting: Four Core Advantages of Minimalist Architecture Construction

Nowadays, this campus networking solution is based on all-optical networks, and through comprehensive optimization of architecture reconstruction, technology selection, and operation and maintenance systems, a high bandwidth, high-performance, and highly reliable network carrier platform has been created for 81 schools in the county. Has the following core advantages:

Minimalist architecture, smooth evolution. The network hierarchy has been streamlined from the traditional three-layer structure to two layers, resulting in a clearer topology. A single optical fiber carries all business data, and the bandwidth can be flexibly adjusted as needed, supporting smooth upgrades from 10G to 200G, perfectly adapting to the strict requirements for network bandwidth and latency in the future development of educational informatization.

Unified operation and maintenance, intelligent management. The device supports plug and play and remote control. Through the unified management platform of intelligent optical communication, the Education Bureau can implement centralized monitoring and strategic distribution of campus networks throughout the county, greatly reducing the operational pressure on each school.

Cost optimization, continuous benefits. Fiber optic materials and passive architecture significantly reduce initial construction investment. In the long run, the characteristic of no power supply for the splitter device continues to save electricity costs, and the high reliability design reduces maintenance frequency and labor costs.

This high bandwidth optical network system has built a high-speed and stable network environment for teachers and students. Teachers can smoothly carry out online teaching and resource sharing, and students can access cloud learning materials at any time, greatly improving the efficiency of teaching and learning.

It is worth mentioning that this plan successfully connects with the regional education ring network and achieves interconnectivity with the data center of the Education Bureau. The Education Bureau can also implement unified strategic management of campus networks, truly building a new intelligent education ecosystem that integrates "teaching, management, and service".

Future prospects: Smart networks pave the way for the development of education

This campus lighting renovation project brings far more than just an improvement in internet speed:

It is a satisfying experience for teachers and students to smoothly carry out smart classrooms!

It is a reliable guarantee that the teaching data in the entire county will never be disconnected!

It is a policy convenience for achieving unified management!

You can control the campus network health status of the entire county with ease and ease from the office!

Deploy an advanced "all-optical network" to pave a future oriented information highway for students in the entire county, allowing every teacher to devote themselves wholeheartedly to teaching innovation. Isn't a good network the core competitiveness of modern smart education?!
