AINOPOL All-Optical Campus Network Solution for General Education

With the continuous advancement of education digitalization policies, the construction of smart campuses in primary and secondary schools, kindergartens and secondary vocational colleges has entered a large-scale implementation phase. Traditional Ethernet is plagued by insufficient bandwidth, isolated multi-systems, complicated wiring, heavy operation and maintenance pressure and high energy consumption, failing to meet the emerging teaching and management demands including synchronous classrooms, standardized examination rooms, safe campus management and home-school live streaming.

With over a decade of in-depth dedication to optoelectronic integrated communications, AINOPOL has developed an all-optical campus network solution applicable to all general education scenarios. Built on the passive optical network (PON) architecture, it establishes a single optical fiber-based multi-service bearing platform that integrates teaching, security monitoring, campus broadcasting, IoT and office communication services. It achieves cost reduction and efficiency improvement, energy conservation and low carbon emission, security compliance and smooth long-term evolution, delivering a practical, easy-to-maintain and highly scalable overall smart campus network solution for basic education institutions.

This paper comprehensively analyzes industry pain points, solution architecture, scenario implementation, core advantages, service guarantees and practical cases, serving as a reference for schools, system integrators and education informatization service providers.

I. Six Core Pain Points of Traditional Campus Networks

In accordance with the requirements of the Action Plan for Deepening Basic Education Curriculum and Teaching Reform (2023-2027), schools across regions are urged to accelerate the construction of new digital infrastructure and improve high-speed campus networks, IoT systems, smart teaching systems and safe campus management systems. Nevertheless, most existing campus networks have various shortcomings that hinder the implementation of smart teaching.

Insufficient bandwidth and excessive latency hinder innovative teaching. Traditional network cabling is limited in transmission distance. Network congestion and high latency frequently occur when numerous terminals are connected simultaneously, resulting in stuttering and frame loss in dual-teacher synchronous classes, high-definition live recording and broadcasting, AR/VR immersive teaching and video patrol in standardized examination rooms, which cannot support regular digital teaching.

Independently deployed systems lead to information silos. Campus broadcasting, surveillance cameras, electronic class boards, access control intercoms, campus telephones and IoT sensors adopt separate wiring and independent equipment management modes. This causes overcrowded cabinets in weak current rooms, heavy wiring workload, numerous equipment fault points and great difficulties in unified scheduling.

Severe shortage of operation and maintenance staff and low fault handling efficiency. Primary and secondary schools in counties and towns generally lack full-time IT maintenance personnel. The complex hierarchical structure of traditional networks prolongs fault troubleshooting. Decentralized equipment management requires separate configuration, upgrade and inspection operations, leading to persistently high labor costs for network maintenance.

High overall costs for network construction and upgrading. Network cables only support transmission within 100 meters, requiring additional multi-level aggregation switches between buildings and branch campuses, which brings high investment in consumables, cabinets and air conditioning supporting facilities. A large number of active devices result in long-term high power consumption. System iteration and renovation demand rewiring, causing substantial repeated investment.

Weak terminal management and potential network security risks. Massive access of teachers’ and students’ mobile phones, teaching tablets, monitoring devices, broadcasting equipment and IoT terminals lacks unified identity authentication and authority control. The absence of Layer 7 traffic protection easily triggers internal network virus invasion, access to malicious websites and bandwidth abuse, making it hard to meet the requirements of Classified Protection of Cybersecurity Level 2.

Inadequate emergency linkage and incomplete closed-loop safe campus management. Surveillance, broadcasting, SOS alarm and access control systems operate independently. Abnormal campus behaviors and sudden help requests can only be dealt with separately, disconnecting early warning, intervention and traceability procedures and delaying responses to campus bullying and unexpected emergencies.

II. Overall Architecture Design of AINOPOL All-Optical Campus Network for General Education

Adopting the simplified passive PON network, AINOPOL builds a unified service bearing platform where one single optical fiber network covers the entire campus. The architecture consists of three layers: core computer room layer, optical distribution layer and terminal access layer, supported by the EAAS cloud operation and maintenance management platform to realize unified management and control of all network devices.

(1) Core Computer Room Layer: Global Network Scheduling Hub

It is centrally deployed with chassis-type OLT, core switches, UC audio & video gateways, firewalls and egress routers, integrating routing switching, voice scheduling, security protection and multi-service forwarding capabilities.

(2) Optical Distribution Layer: Dual-path Optoelectronic Integrated Cabling System

Adopting a dual-path parallel design starting from OLT, it builds a lightweight optical distribution network via passive optical splitters and active optical splitters (optical sockets) respectively. It retains the core advantages of PON network including simplified structure and low power consumption, and solves the problems of long-distance power supply and multi-service bearing at terminal ends through active splitters and composite optoelectronic cables, balancing construction cost, deployment flexibility and service expandability.

(3) Terminal Access Layer: Full-scenario Optoelectronic Integrated Terminal Matrix

Standardized optoelectronic integrated terminals are matched for diverse general education scenarios. A single terminal supports wired network, Wi-Fi 6 wireless network, IP telephone and POE power supply simultaneously, featuring plug-and-play and easy construction.

Classroom Scenario

8-port POE ONU terminals are deployed with optical fibers directly reaching classrooms, carrying wireless APs, high-definition cameras, IP broadcasting, electronic class boards and examination room signal jammers synchronously. The renovation of a single classroom can be finished within one day, and nearby wiring reduces material consumption. It supports visual online classroom inspection, enabling school leaders to remotely monitor real-time classroom conditions and conduct targeted voice broadcast intervention against irregular behaviors.

Office Scenario

86-type wall-mounted optical APs and desktop optoelectronic integrated APs cover teachers’ offices, meeting rooms and libraries. They allow wired access for 8 terminals and analog telephone access, equipped with Wi-Fi 6 AX3000M high-speed wireless network and millisecond-level intelligent roaming to ensure uninterrupted mobile teaching.

Dormitory Scenario

Outdoor Public Area

Ceiling-mounted optoelectronic integrated APs and outdoor optical terminals cover playgrounds, corridors and school gates. Linked with surveillance cameras, they realize AI human shape recognition and trigger warning audio broadcast upon abnormal events, establishing a pre-prevention mechanism against campus violence.

(4) EAAS Cloud Operation & Maintenance Management Platform

Supported by self-developed EAAS cloud O&M platform accessible via web and mobile APP, it enables unified visualized management of all campus devices, including automatic device online access, second-level fault location, remote batch configuration and upgrade, automatic wireless channel optimization and real-time alarm push. Built-in Portal authentication supports hierarchical identity verification via DingTalk accounts and SMS messages, and white list management controls students’ internet access privileges, allowing administrators to conduct daily maintenance without professional network expertise. With open API interfaces, the platform can connect with third-party systems such as smart educational administration, security monitoring and campus card systems to eliminate data silos.
