Copper and fiber-optic cabling technology are combined in an optimum cabling concept – simple, flexible, cost-efficient. The single-sided and double-sided pre-assembly of our LAN cabling systems permits time savings at the installation site of up to 15%.

Conventionally structured cabling with enhanced flexibility

Do you want more flexibility in the spatial layout of your workplaces? PreCONNECT® flexNET is the perfect response to the demands of the increasingly dynamic working processes in the office environment, in manufacturing and in building management. The extension and restructuring work can be performed without interrupting ongoing operations.

The right solution - depending on the requirements and the demands placed on your building network


Structured building cabling with increased flexibility in the spatial layout of workplaces

PreCONNECT® flexNET
The additional flexibility is achieved by interconnecting a passive copper consolidation point (CP) in the tertiary sector. The great advantage: Completely new end user connections become available at the passive consolidation point and existing workplaces can be moved. The extension and restructuring work can be performed without interrupting ongoing operations. Do you have any questions about planning, installing or maintaining your building cabling?

Structured building cabling with low administrative overhead

The innovative focus of the solution lies in the forward-looking glass fiber technology which possesses “virtually unlimited transmission capacity”. However, this is just one aspect of PreCONNECT isoNET®. Copper technology continues to play an important role in building cabling. Alongside the time savings resulting from the pre-assembled data cables, another advantage of the standards-compliant network solution is the low administrative overheads resulting from the centralization of the active components in the floor distributors.


The advantages of a pre-assembled cabling solution

Pre-assembled cables such as PreCONNECT® and well-trained personnel bring extra power to the installation site. The cable length is determined as early as the preliminary planning stage. This eliminates offcuts and cable waste at the installation site as well as unnecessary measurements. At the site, the cables simply have to be laid and connected. For your building cabling, benefit from an optimized solution that meets the criteria of standard EN 50173.

Any other questions?

Here you will find answers to various questions on the topic of structured cabling. 

What does structured cabling mean?

Conventional structured cabling represents a concept that permits service-independent, universally applicable pre-cabling in order to support network-based information and communications applications operating between buildings. This means that the type of cable and the employed structure guarantee the use of all known protocols, the use of all technologies (Ethernet, Fast Ethernet, Gigabit Ethernet, Token Ring, FDDI, ATM), as well as the use of a range of services (ISDN, SNA). This is intended to prevent incorrect installation and expensive extensions and simplify the installation of new network components. Structured cabling is subdivided into the primary, secondary and tertiary cabling sectors.

What is important in terms of structured cabling?

The generally applicable structure of the cabling is essentially defined by the corresponding standards. However, the standardized scope provides very little flexibility. The challenge therefore lies in taking account of terminal device connections that will be required in the future within the broadest possible planning horizon. This is because the architecture of a conventional structured cabling solution generally makes integrations and extensions very expensive – typically costing 2 to 3 times more than an initial installation. In most cases, this is the key problem, because the requirements placed on the cabling infrastructure often change due to spatial reorganizations or restructuring work. Although “watertight” future planning that caters for numerous different eventualities is possible, such an approach vastly increases the overall project costs (Capex).

What is referred to as primary or campus cabling?

The primary cabling is the connection between the buildings at a site and is also referred to as campus or site cabling. This extends from the site distributor through to the connected building distributors. The primary cabling often requires long cable lengths of several hundred metres. Fiber-optic cables are particularly well suited for cabling between buildings thanks to their low attenuation, coupled with a particularly high data transmission rate. Another argument in their favour lies in their insensitivity to electromagnetic interference and the galvanic isolation of buildings they produce.

What is referred to as secondary or story cabling?

The secondary cabling extends from the building distributor through to the connected downstream distributors, which are also known as floor or story distributors. Here again, cable lengths of over 100 meters are often required, thus making the use of copper cables impossible. In addition, fiber-optic cables also permit the galvanic isolation of individual stories or building sections at the level of the data cabling.

What is referred to as tertiary or floor cabling?

The tertiary sector provides for the cabling of floor or story distributors through to the connecting sockets and is therefore often referred to as floor cabling. In conventional structured cabling, the floor distributor is connected to the connecting sockets for the terminal devices in a radial configuration. In the cabling standard, the length of the path between the distributor and the connecting sockets is limited to max. 90 m plus 2 times 5 m. Twisted-pair copper cables are used for these relatively short paths.

What are the advantages of pre-assembly compared to a splice solution?

In principle, the costs are similar because the use of materials is the same. However, manpower is becoming an ever rarer and more expensive commodity at the installation site. The great advantage of pre-assembled cables lies in their fast, simple installation. Thanks to the time saved, it takes fewer people to implement a project. Alternatively, multiple projects can be realized with the same personnel level. Pre-assembled cables are also factory-measured. By contrast, splice solutions or on-site installations always have to be checked using measurement technology prior to acceptance and this operation consumes additional time. As the last link in the implementation chain, the “data systems engineering” sector often has to work under considerable time pressure. The use of pre-assembled cables saves time during the project and may even help make up any time that has already been lost.
