Angola Power Corridor Communication Supporting Project Case Study｜OPGW Fiber Optic Cable Delivery and Full Range of Outdoor Fiber Optic Cable Support

Angola Power Corridor Communication Supporting Project Case Study｜OPGW Fiber Optic Cable Delivery and Full Range of Outdoor Fiber Optic Cable Support

Project Overview

This project is located along a power line and highway corridor in Angola. The client's objective is to construct a stable fiber optic communication channel within the existing power line corridor for backbone transmission, dispatch communication, and subsequent network expansion. It has been finalized that the core requirement for this project is OPGW (Optical Ground Wire). The project also has branch access and extension requirements, necessitating the use of standard outdoor fiber optic cables to accommodate different routes and protection levels.

Key Customer Requirements

Using OPGW as the backbone, suitable for the operating environment of power line corridors

Reliable for long-term outdoor operation, stable transmission, and weather-resistant structure

Stable factory supply, good batch consistency, facilitating acceptance and subsequent maintenance traceability

Requires simultaneous support for outdoor optical cables in overhead/duct/direct burial modes, facilitating future expansion

Our core supplied product: OPGW optical cable (confirmed model direction for this project)

OPGW Product Positioning

OPGW combines the functions of optical fiber communication units and overhead ground wires, suitable for communication carrying scenarios in power line corridors, and can be used for power system communication and supporting communication network construction. This type of product is structurally designed to balance mechanical performance with long-term outdoor weather resistance, meeting the long-term operational requirements of power lines.

Structural Highlights

As can be seen from the cross-sectional structural diagram of the OPGW, the product consists of an outer layer of multi-layered metal wires for support and load-bearing, with a core of a stainless steel tube containing integrated optical fibers. The outer layer employs a combination of aluminum-clad steel wires and aluminum alloy wires to balance strength, corrosion resistance, and long-term operational stability.

Our OPGW Delivery Support

Structure and Configuration Support: We can provide configuration suggestions based on the line corridor environment, operational requirements, and communication planning.

Quality Consistency: Factory production and batch management facilitate project acceptance and subsequent traceability.

Complete Supporting Capabilities: In addition to OPGW, we also have the capability to supply multiple types of outdoor optical cables, supporting project extensions and branch access.
