——A Next-Generation Optical Fiber Cabling Management System Built with SuperMap iServer
Optical fibers, the "nerve network" of modern society, are laid underground and overhead throughout the city of Yokohama. Our comfortable digital lives are supported by this countless optical fiber network. However, maintaining and managing this "invisible infrastructure," so essential to society, is an extremely complex and challenging task for telecommunications companies.
Paper drawings, CAD data, and Excel ledgers... Static information managed disparately makes it impossible to accurately grasp the entire picture of the ever-changing network.
In this article, we will use "SuperMap iServer," the core of Web GIS, as a hub to consider how the entire lifecycle of optical fiber networks, from planning and design to maintenance and management, and even fault response, can be transformed.
1. Why is Web GIS Essential for Optical Fiber Management?
Traditional management methods have several deep-rooted challenges.
l Information silos: Blueprints (CAD), equipment ledgers (Excel), and customer information (DB) are managed by different departments, resulting in fragmented information.
l Stale information: Changes made in the field aren't immediately reflected in office drawings and ledgers, resulting in information quickly becoming outdated.
l Disconnection between the office and the field: Field workers rely on paper drawings, preventing the office from accurately understanding the situation on the ground.
Web GIS fundamentally solves these issues. With SuperMap iServer at its core, it creates an environment where anyone within an organization can access a single source of truth (Single Source of Truth) anytime, anywhere from a web browser or mobile device.
2. SuperMap iServer Enables "Full Lifecycle" Management
The SuperMap platform provides end-to-end support for the entire lifecycle of optical fiber networks.
(1) Planning and Design
The web GIS application overlays open data such as the national census and commercial data such as people flow data to select the optimal candidate locations for new cable installation routes. The location of existing infrastructure (utility poles, utility conduits, etc.) can be clearly understood on the map, enabling efficient design.
(2) Construction and Completion
On-site construction teams use a mobile GIS (SuperMap iMobile) to record the exact location information (completion information) of the installed cables and equipment on the spot. Photographs are linked to the location information and saved, and the data is instantly updated in a central database via SuperMap iServer. This prevents discrepancies between drawings and reality.
(3) Maintenance
In the office, a dashboard on a web browser allows centralized management of all information, such as the usage status of conduits and core wires and equipment inspection history, linked to maps. This dramatically improves the efficiency of tasks such as listing all customers linked to a specific cable or planning the replacement of aging equipment.
(4) Troubleshooting Phase
This is where Web GIS truly shines. When a customer reports an internet outage, an operator clicks on the customer's location on Web GIS. The system automatically traces the optical fiber route leading to that point upstream, providing powerful support for pinpointing the fault, such as determining whether the cable in this section is likely damaged or whether the equipment at this branch point is malfunctioning. This dramatically reduces the time to recovery.
3. Seamless 2D and 3D Integration
Optical fiber networks exist in complex three-dimensional spaces, including underground utility tunnels, above-ground utility poles, and piping within buildings.
SuperMap iServer excels at seamlessly delivering 2D maps for a broad understanding of the area and 3D models for a detailed understanding of congested areas. Being able to intuitively understand in 3D how underground pipelines intersect with other infrastructure (gas pipes, water pipes) is essential for improving construction safety and avoiding unnecessary problems.
4. Summary: Building a Network Digital Twin
Optical fiber management with SuperMap iServer at its core is more than just mapping. It's about building and operating a digital twin of your ever-changing network.
The entire network lifecycle, from planning to maintenance and fault response, is proactively managed based on data. This enables telecommunications carriers to improve service quality, reduce operational costs, and support our comfortable digital society in a more resilient way.
