Angola Power-Line Corridor Communications Project Case Study|OPGW Supply as the Backbone + Outdoor Fiber Optic Cable Portfolio Support

Project Overview

This project is deployed along an electricity transmission corridor running parallel to a highway in Angola. The client’s goal is to establish a stable fiber-optic communication channel within the existing power-line corridor to support backbone transmission, dispatch communications, and future network expansion. The finalized core requirement is OPGW (Optical Ground Wire) as the main backbone solution. In addition, the project includes branch access and route extensions, which require standard outdoor fiber optic cable models to match different routing conditions and protection needs.

Key Customer Requirements

OPGW as the primary backbone solution, aligned with power-line corridor operating environments

Long-term outdoor reliability, stable transmission performance, and weather-resistant structure

Stable factory supply and batch consistency, supporting acceptance and long-term maintenance traceability

Simultaneous support for multiple outdoor deployment needs, including aerial, duct, and direct-buried routes for future expansion

Core Supplied Product: OPGW (Optical Ground Wire)

OPGW Product Positioning

OPGW integrates optical fiber communication capability with the function of an overhead ground wire, making it a proven solution for communication carrying in power-line corridors. It supports both power system communications and the build-out of corridor-based fiber networks. The structural design focuses on balancing mechanical strength with long-term outdoor durability, meeting the operational requirements of power transmission environments.

Structural Highlights (Based on the Cross-Section Diagram)

From the OPGW cross-sectional structure, the cable features a multi-layer metal wire outer structure for support and load-bearing. At the center, a stainless steel tube houses the optical fibers, providing stable protection for the fiber unit. The outer layers combine aluminum-clad steel wires and aluminum alloy wires, delivering a practical balance of strength, corrosion resistance, and long-term operational stability.
