When the soccer world championships kick off on 9 June 2006 in the Allianz Arena, Munich, Germany, cables and components from international supplier Datwyler Cables+Systems will play a major part.

High-performance Unilan and Optofil products from this international manufacturer will provide a substantial part of the arena's passive network cabling infrastructure.

A powerful combination of copper and fibre-optic cables and their corresponding components will provide the telephone, data and video backbone to this extravagant temple of soccer.

Generous media facilities will enable journalists to dispatch data and pictures all over the world.

Safety cables and components from Datwyler will also play a vital role in the fire protection concept of the Allianz Arena.

Datwyler's fire safety system concept comprises an integrated system of cables, components and installation methodology which has been proven to provide functional integrity.

In all, 4000km of Datwyler cable have been installed in the Allianz Arena for data and energy distribution.

Datwyler's Unilan Compact Solution (Unilan CS) provides the basis of the data network in the Allianz Arena.

This comprises high-performance Uninet 7702 twisted-pair cat 7 copper cable, shielded 24-port patch panels (CS 24/8), patch cords and outlets in various versions.

The high performance reserves of the cables ensure high-fidelity transmission of all services - data, telephone and video - and guarantees compliance with all existing standards.

The soccer stadium network is optimised with Optofil hybrid cables manufactured with single-mode and multi-mode fibres, and with corresponding connecting components as well.

The safety cables from Datwyler guarantee that, in the case of a fire, a functional integrity of at least 30 minutes is ensured for the areas of detection, alarm and evacuation.

In the case of fire suppression, smoke handling and extinguishing systems functional integrity amounts to 90 minutes.

Datwyler safety cables are also used for the signal and control transmission of the loudspeaker installations in the soccer stadium.

The Allianz Arena has received the German Fire Protection Award 2003 for their exemplary fire protection concept with, among others, 4600 fire alerts and approximately 800km of fibre-optic cables.

Installation was undertaken by VA Tech Elin EBG on behalf of Alpine Bau Deutschland as general contractor and HVB Immobilien as general planner.

In selecting cables and network components, the companies involved focused on high quality and on bandwidth reserves, which can also satisfy future needs and applications.

A central requirement was network access in the stadium: this requirement was very exacting with 99.999 per cent or six minutes of interruption at the maximum per year.

Datwyler safety cables and components are used where large crowds of people require special safety measures such as in high-rise buildings, administrative buildings, hospitals and airports.

They fulfil the most stringent European directives in special areas such as road and railway tunnels.

As a competent partner, Datwyler Cables+Systems offers one-stop complete cabling infrastructures.

Cable and system components together with consulting and logistic services form a comprehensive customer-specific package.

The Allianz Arena is an architectural masterpiece that cost EUR340million (£232million or $412million) and offers seating for 66,000 spectators.

Of the total usable area of 170,000m2, the new building hosts in addition to the stadium two restaurants for the soccer fans with 1500 seats each, a family restaurant, 28 kiosks, adventure parks, shops for soccer fans, offices, conference rooms and generous media facilities.
