All-Optical AI Education Network Carrying Solution Based on DCI-BOX

As the "Data-Intelligence Integration" era reshapes the landscape of education, digital infrastructure is undergoing a milestone transition from basic connectivity to high-quality performance. Emerging applications, such as 4K/8K interactive classrooms and cross-campus AI supercomputing collaboration, demand a network that offers massive bandwidth, ultra-low latency, and strict security isolation. Sino-Telecom’s All-Optical AI Education Network Carrying Solution, based on the DCI-BOX platform, is specifically designed to address these core challenges.

Challenges from "Connectivity" to "All-Optical" Quality

Emerging applications such as AI-assisted teaching, cross-campus computing collaboration, and 4K/8K interactive classrooms are significantly increasing network demands:

· Multi-service isolation: Diverse services (teaching, administration, video, exams, etc.) require secure and physically isolated transmission.

· Ultra-high bandwidth: HD video and immersive technologies (VR/AR) are driving rapid traffic growth.

· High reliability: Critical services demand zero interruption and stable low-latency performance.

· Efficient fiber utilization: Limited fiber resources require higher transmission efficiency.

· Simplified O&M: Lean IT teams need intelligent management and fast fault detection.

· Computing resource sharing: Seamless cross-campus resource access is essential.

An intelligent, high-quality all-optical network has become the inevitable foundation for modern education.

Sino-Telecom DCI-BOX All-Optical Education Network Solution

Based on proprietary DCI-BOX WDM technology, access OTN, and FTTx solutions, Sino-Telecom introduces a “three-layer integrated” all-optical DCI solution for the education sector, covering key scenarios such as multi-campus interconnection, disaster recovery, supercomputing collaboration, and local access.

Solution Architecture

The architecture is structured in three coordinated layers. At the core layer, DCI-BOX WDM devices form the backbone network, delivering high-capacity transmission with support for 3.2T/6.4T per device and 48/96-channel DWDM. Building on this foundation, the aggregation and access layer uses access OTN devices to enable flexible service connectivity across campuses and institutions, supporting multiple interfaces such as FE, GE, 10GE, 100GE, and STM-N, while FTTx solutions provide adaptable and scalable campus access. On top of this, the unified management and control layer is implemented through an NMS system, which offers centralized management of topology, configuration, alarms, and performance, supports SDN controller integration, and ensures efficient multi-vendor network management.

Application Scenarios

Scenario 1: High-Speed Multi-Campus Interconnection

DCI-BOX WDM enables all-optical interconnection with 100G/200G/400G over a single fiber pair, ensuring physical isolation, <1 ms latency, and real-time interactive teaching.

Scenario 2: Geo-Redundant Disaster Recovery

OTN hard pipes build a “local + remote” active-active architecture, delivering RPO ≈ 0 and RTO < 30 min with automatic switchover for secure data protection.

Scenario 3: Cross-Region Supercomputing Collaboration

DCI-BOX with RoCE switches enables microsecond latency and zero packet loss, supporting cross-campus GPU scheduling for AI and HPC workloads.

Scenario 4: FTTx Campus Access

GPON/FTTx replaces copper with simplified OLT–ODN–ONT architecture, offering low cost, easy O&M, and seamless integration with the DCI backbone.

Application Case — Municipal Education Network

Project Background

This municipal project aimed to establish a high-performance backbone network connecting educational institutions across 16 districts and counties. The primary requirement was to provide a highly reliable and secure transmission path for critical services, particularly the Examination Specialized Network, which demands strict physical isolation and zero downtime.

Technical Solution

Core Backbone: Sino-Telecom WDM equipment was deployed at four core nodes, establishing a 16-wavelength core ring to serve as the city’s primary transmission artery.
District Aggregation: Connections from district information centers to the core nodes utilize 8-wavelength links.
Hard Pipe Isolation: A single, dedicated wavelength is exclusively allocated to the examination network, achieving true hardware-level isolation from other service traffic.

The implementation successfully achieved complete physical isolation for the specialized examination network, guaranteeing zero communication interference during critical exam periods. Beyond security, the project integrated the entire municipal infrastructure into a unified management platform, which has drastically improved O&M efficiency.
