A quantum leap in speed High growth rates in fibre optic expansion are enabling access to the competitiveness of the “gigabit age”, and the cable, wire and pipe industries have long been ready to play a decisive role in shaping this future. Countries such as Germany and the UK are turning to high speed data highways, while Korea, Japan and Spain already have very high fibre penetration rates of 87, 84 and 81 per cent, respectively.

Fibre optic cables are faster than conventional copper cables and transport more data

Fibre optic cables are many times faster than conventional copper cables and can transport significantly more data, while requiring little space and consuming less energy. high precision, and this can be ensured by using measuring and control devices such as those manufactured by Sikora. The company offers a new technology for high-precision tensile force measurement in a stand-alone system that employs the principle of birefringence with a measurement rate of up to 10 kHz. Rosendahl Nextrom is a fibre optic specialist that sees itself as a one-stop shop for production equipment. The company’s core competencies include its manufacturing solutions for the production of optical glass, the drawing of glass fibres for telecommunications and special applications, the coating of fibres, the production of ribbons, proof tests and the production of glass fibre cables. For the loose and tight buffering of glass fibres, cable lines are required in addition to hose extrusions for fibre bundles and fibre ribbons. The company also offers systems for the stranding of buffered fibres up to the sheathing process for fibre optic cables. The protection of the glass fibre is also essential. A single fibre has a core, a cladding glass and an outer cladding. “The mantle ensures the guidance of the lightwave signals; the outer sheath gives the glass fibre flexible and robust properties due to its nature of plastic,” explained a spokesperson for the glass fibre provider Telekom. This prevents the fibre from breaking during bending and losing its function as an optical waveguide. The optical signals cannot leave the core, unlike the copper cable that transports data by means of electricity and loses data over long distances. Rautomead Ltd Rautomead will be introducing its new RIC 400 model break-ring, continuous casting technology, which has been developed to process cobalt alloy, nickel alloy and iron alloy wire rods from 2.5 to 50mm diameter. The company will also present its RS range of graphite furnace continuous casting machines for the manufacture of extra-low oxygen content CuOF rod and for the production of high quality conductor alloy rods.

Only seven countries have a fibre share of 70 per cent or more of total fixed broadband subscriptions, according to the OECD (Organisation for Economic Cooperation and Development). Germany, for example, is behind in the international comparison with a fibre optic expansion rate of less than 25 per cent – 74 th among 84 assessed countries. Its federal government launched a “gigabit strategy” to ensure that fibre optic connections are available nationwide by 2030. In order to make this possible, fast planning and approval procedures are implemented, among other things. In addition, alternative laying techniques are to be used more frequently for fibre optic expansion. The implementation of Industry 4.0 will require powerful data carriers. Even in households, fast web-surfing is expected, and data rates are rising rapidly. On average, data traffic climbs by more than 30 per cent each year. QED Wire Lines Inc QED specialises in equipment for in-line heat-treating, cleaning and coating of steel wire. Its furnaces are custom built for multi-strand annealing, stress relieving, patenting and tempering processes. With patented flow technology, the fluid systems integrate cleaning efficiency with high wire speeds. The liquid metal furnaces apply heavy and commercial coatings of zinc, aluminium and Galfan®.

In addition to underground laying and above-ground laying on masts, outdoor fibre optic cables are blown with compressed air into small pipes that were laid in advance in the ground or in jacket pipes. The pipes have an inner diameter of four to eight millimetres and are often designed in a pipe assembly with up to 22 pipes. The fibre optic cables (ø 2.3 to 6.5mm) are blown into these pipes with special air compressors, up to 2,000m at a time. Common fibre optic earth cables include four cables with twelve individual fibres each. Worldwide demand for cables and pipes for fibre optic technology is growing. In order to keep up with this demand, production needs to be expanded and new production facilities set up. For example, egeplast is building a new microduct production hall to ensure reliability of delivery for the expansion of the fibre optic network in view of the increasing demand for tube bundles, which consist of several microduct mono tubes. The new 11,000m 2 production hall doubles its production capacity for microducts. Trends and highlights from the wire, cable and tube industries can be experienced at wire and Tube 2024, from 15 to 19 April 2024 in Düsseldorf, Germany.
