Manufacture of fibre optic cables

NACE v2.1 Code: C27.31

About manufacture of fibre optic cables

NACE code 27.31 covers the manufacture of fibre optic cables, a critical component in modern telecommunications infrastructure. This industry plays a vital role in enabling high-speed data transmission and connectivity across the globe, supporting the growth of the digital economy and the increasing demand for reliable, high-bandwidth communication services.

Production process

The production of fibre optic cables involves several key steps. First, optical fibres are manufactured by drawing thin strands of pure glass or plastic. These fibres are then coated with protective layers, such as acrylate or polyimide, to enhance their durability and resistance to damage. The coated fibres are then assembled into cables, which may include additional protective sheaths, strength members, and other components to ensure the cable's integrity and performance.

Production inputs

The main inputs required for the manufacture of fibre optic cables include high-purity silica or other optical-grade materials for the fibre core, as well as various polymers and metals for the protective coatings and cable components. Specialized machinery, such as fibre drawing towers, cabling equipment, and testing apparatus, are also essential for the production process. Additionally, the industry relies on a skilled workforce with expertise in materials science, optics, and cable engineering.

Production outputs

The primary output of the fibre optic cable manufacturing industry is, of course, the fibre optic cables themselves. These cables are then consumed by a range of other industries, including 61.10 Wired telecommunications activities, 61.20 Wireless telecommunications activities, and 42.22 Construction of utility projects for electricity and telecommunications, as they are integral to the deployment and operation of modern telecommunications networks.
