ADSS optical cables in smart cities: perspectives for digital transformation and energy transition — subsidies for infrastructure consulting and support for urban management teaching

Abstract

This study analyzes the technology of all-dielectric self-supporting (ADSS) optical cables and similar ones in the context of Digital Transformation and the Energy Transition of cities. Connectivity is a critical infrastructure for the viability of Smart Cities, justifying the analysis of these cables as a robust, low-cost, and high-efficiency solution for data transmission. The general objective is to analyze ADSS optical cable technology, investigating its patent protection, main innovation agents, technical-patent classifications, future trends, and the Brazilian scenario. The research combines literature review, desk research, and technological forecasting based on a portfolio of 2,354 patents. The analysis considered publication dates, languages, territories, IPC classifications, inventors, and leading companies. The study points out opportunities and challenges for Brazil's strategic positioning, highlighting the need for innovation policies and the strengthening of the national industry. The study highlights that ADSS cables are an essential element for telecommunications infrastructure, contributing to high-speed connectivity and the integration of sustainable energy systems. The results of this study offer practical support for network infrastructure consultancies and serve as a reference for case-based teaching in the areas of engineering and smart city management.
