About optical fibre cables made up of individually sheathed fibres

cpc code 4636 covers the production of optical fibre cables made up of individually sheathed fibres. These cables are a critical component of modern telecommunications infrastructure, enabling the high-speed transmission of data, voice, and video signals over long distances. As the global demand for reliable and high-capacity communication networks continues to grow, the optical fibre cable industry plays a vital role in supporting the digital transformation of economies and societies worldwide.

Production process

The production of optical fibre cables under cpc code 4636 involves several key steps. First, individual optical fibres are manufactured by drawing thin strands of glass or plastic from a preform. These fibres are then coated with a protective sheath, which can be made from various materials such as acrylate or polyimide. The sheathed fibres are then bundled together and encased in an outer jacket, typically made of polyethylene or other durable polymers. The final step involves the application of additional reinforcing elements, such as strength members or armoring, to enhance the cable's durability and resistance to physical stress.

Production inputs

The main inputs required for the production of optical fibre cables under cpc code 4636 include high-purity silica glass or plastic raw materials for the optical fibres, various polymer compounds for the protective sheaths and outer jackets, and specialized machinery for the fibre drawing, coating, and cable assembly processes. Additionally, the industry relies on advanced testing and quality control equipment to ensure the reliability and performance of the final products.

Production outputs

The primary output of the optical fibre cable industry under cpc code 4636 is, of course, the optical fibre cables themselves. These cables are then consumed by a wide range of industries, including 4635 Telecommunications equipment, 4637 Other communication equipment, and 4641 Electric motors, generators and transformers, as they are essential components in the construction and maintenance of modern telecommunications networks.
