Goilips Smart Campus 10G/100G Dual-Active Backbone Ring Solution

Overview

Modern smart campuses are rapidly digitizing teaching, research, and administration. Campus networks now support live online classes, research big-data transfer, smart security monitoring, campus card systems, and other mission-critical services.

If a core backbone link suffers a single-point failure or is interrupted by lightning, surge events, or external fiber damage, teaching and management systems across the campus can be affected. Traditional campus networks built with single-chain or tree topologies lack sufficient physical redundancy and disaster resistance.

This solution uses Goilips 40G/100G ER4 long-life single-mode optical modules with ERPS (G.8032) / RRPP dual-active ring protection protocols to build highly available core backbone networks for multi-campus smart campuses, supporting 40km spans, hardware-level lightning and surge protection, and 50ms self-healing.

Applications

Multi-Campus Backbone Interconnect

For long-distance 10G/100G core links between main campuses, new campuses, medical campuses, and research parks across several kilometers to tens of kilometers.

Core-to-Aggregation Dual-Active Ring

Connects teaching buildings, libraries, laboratories, data centers, and dormitory aggregation nodes with millisecond-level redundancy protection.

High-Density Campus Video Surveillance

Ensures high-throughput, smooth, and uninterrupted transmission of thousands of HD/Ultra-HD security camera streams to the data center.

Deployment & Architecture

Between the main campus core equipment room and branch-campus or building aggregation rooms, dual-fiber bidirectional long-reach modules build a non-blocking closed-loop topology. Active-active or hot-standby links provide load sharing and automatic failover.

Key Benefits

1

Always-On 7x24 Smart Campus Network

Dual-active ring architecture, millisecond self-healing, and lightning protection remove single points of failure and protect core campus services during severe weather or fiber cuts.

2

Lower Operations Cost

Reduces large-scale outages caused by lightning or surge damage to core ports and can cut emergency on-site repair incidents by more than 80%.

3

Protect Campus Assets and Upgrade Smoothly

Standard QSFP+/QSFP28 interfaces are compatible with mainstream campus network equipment from Cisco, Huawei, H3C, Ruijie, and others, supporting current upgrades and future bandwidth growth.
