Build Foundation with All-Optical Network, Empower Smart Education for the Future!

AINOPOL Helps Zhuhai New Thinking Secondary Vocational School Upgrade Smart Campus Network

As a benchmark institution dedicated to vocational skill training, Zhuhai New Thinking Secondary Vocational School has always kept pace with the digital transformation of vocational education, with digital services such as smart classrooms, practical training teaching, online examinations, campus IP broadcasting and remote conferences fully implemented across the campus.

With the growing network demands of teachers and students, the inherent drawbacks of the original traditional network architecture including insufficient bandwidth, isolated services and poor stability have become increasingly prominent, failing to meet the development needs of modern vocational education. In response, AINOPOL has tailored an integrated all-optical networking solution for the school to build a new generation of high-speed, stable, secure and scalable campus network, laying a solid digital foundation for the digital upgrading of vocational education.

I. Upgraded Demands Bring Bottlenecks to Traditional Networks

With the in-depth advancement of vocational education digitalization, the school has put forward all-round upgrading requirements for campus networks, which can no longer be satisfied by the original network structure. The core pain points are mainly reflected in four aspects:

Poor internet experience and insufficient support for high-bandwidth services. Network stuttering occurs frequently among all teachers and students. High-bandwidth applications including high-definition video teaching, online examinations and remote conferences often suffer from buffering and disconnection, seriously hindering teaching progress and user experience.

Conflicting multi-services causing mutual interference. Simultaneous transmission of data, voice and video services leads to bandwidth contention, resulting in noisy voice calls and out-of-sync video courses, which greatly undermine the operational performance of various teaching applications.

Insufficient reliability and imperfect security defense. Traditional networks feature poor stability, which may cause occasional interruptions of core teaching services. Meanwhile, the lack of a comprehensive security system brings potential risks such as network attacks and teaching data leakage.

Weak scalability restricting long-term development. Complicated wiring of traditional networks requires large-scale line reconstruction when adding new teaching equipment and expanding smart campus services, which involves high costs and long construction cycles and cannot adapt to the school’s long-term capacity expansion needs.

II. All-Optical Network Breaks Dilemma, Customized Solution Empowers Smart Campus

In view of the school’s core demands and practical operational pain points, the AINOPOL team conducted in-depth research on campus building layout and teaching business processes, and launched a full-link all-optical networking solution covering core layer, aggregation layer and access layer to effectively solve various network difficulties on campus.

One Optical Fiber Covers the Whole Campus, All-Optical Links Realize High-speed Campus Interconnection

Adopting all-optical network technology, optical fibers serve as the exclusive transmission medium connecting core computer room nodes with all teaching and living areas on campus. All data transmission is completed within the optical network, thoroughly breaking the bandwidth bottleneck of traditional copper cables. It enables high-speed interconnection among teaching buildings, dormitory buildings, libraries, practical training buildings and other functional zones, establishing bottleneck-free transmission links for the entire campus network.

10G Core Delivers Powerful Computing Power to Build a Stable Network Hub

10G core cloud switches are deployed at the core layer to deliver powerful data switching and processing capabilities, ensuring stable and reliable operation of the whole campus network. High-performance integrated routing devices are also configured to realize efficient internet access and route forwarding, enabling teachers and students to smoothly access online resources and completely eliminate network lag and disconnection issues.

Flexible Networking via Passive ODN for Full-area Zero-blind-spot Coverage

Passive ODN optical splitters are deployed at the aggregation layer to efficiently converge and distribute optical signals. Multiple ONU terminals are connected through PON interfaces of OLT devices to achieve full campus network coverage. Requiring no power supply, passive devices feature low failure rates and strong anti-interference performance, which greatly reduce operation and maintenance difficulties. With flexible wiring layout, the solution perfectly adapts to complex campus architectural layouts and realizes full-coverage network signals without dead zones.

On-demand Deployment at Access Layer to Fit All Teaching and Living Scenarios

POE ONU terminals are installed on demand in teaching buildings, dormitories, libraries and other areas, providing Ethernet and telephone interfaces. Teachers and students can connect computers, teaching terminals, telephones and other devices to the network via ONU devices to access high-speed internet, make voice calls and conduct high-definition video teaching, fully meeting network demands in teaching, office and daily living scenarios.

Isolated and Coordinated Multi-services Ensure No Interference Among Teaching, Voice and Video Services

By applying VLAN virtual local area network technology, the campus network is divided into multiple logical subnets to realize logical isolation of data, voice, video and other services and avoid mutual interference. Meanwhile, the QoS quality of service mechanism sets high transmission priority for core services such as online examinations and smart teaching, ensuring the smooth and stable operation of key educational businesses at all times.
