The right solution – Tailored to your requirements
Choose the best option depending on the specific requirements and demands placed on your building network.

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

PreCONNECT^® flexNET
Additional flexibility is achieved by incorporating a passive copper consolidation point (CP) in the tertiary sector. The key advantage: entirely new end-user connections can be established at the passive consolidation point, and existing workplaces can be relocated as needed. Extensions and restructuring can be carried out without disrupting ongoing operations.

Structured building cabling with low administrative overhead

The innovative strength of this solution lies in its forward-looking glass fibre technology, offering "virtually unlimited transmission capacity." However, this is only one facet of PreCONNECT^® isoNET^®. Copper technology remains an essential component in building cabling.
In addition to the time savings gained through pre-assembled data cables, another significant advantage of this standards-compliant network solution is the reduced administrative overhead, achieved through the centralisation of active components in the floor distributors.

The advantages of a pre-assembled cabling solution

Pre-assembled cables such as PreCONNECT^® and well-trained personnel significantly enhance efficiency at the installation site. The cable lengths are determined during the preliminary planning phase, eliminating offcuts, cable waste, and unnecessary measurements at the site. Once on-site, the cables only need to be laid and connected. This optimised approach ensures that your building cabling meets the requirements of the EN 50173 standard.

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

Conventional structured cabling refers to a concept that allows service-independent, universally applicable pre-cabling to support network-based information and communication applications between buildings. This means that the type of cable and its structure ensure compatibility with all known protocols, various technologies (Ethernet, Fast Ethernet, Gigabit Ethernet, Token Ring, FDDI, ATM), and a wide range of services (ISDN, SNA). The primary goal is to prevent installation errors and costly extensions while simplifying the addition of new network components. Structured cabling is divided into three sectors: primary, secondary, and tertiary cabling.

The general structure of structured cabling is defined by corresponding standards. However, these standardized frameworks offer limited flexibility. The main challenge lies in anticipating future terminal device connections within the broadest possible planning horizon. The architecture of conventional structured cabling solutions often makes subsequent integrations and extensions very costly—typically 2 to 3 times more expensive than the initial installation.
This is a critical issue since the requirements for cabling infrastructure frequently change due to spatial reorganizations or restructuring work. Although comprehensive future planning that accounts for various potential scenarios is possible, such an approach significantly increases the overall project costs (Capex).

Primary cabling, also known as campus or site cabling, connects the buildings within a site. It extends from the site distributor to the connected building distributors. Due to the often required cable lengths of several hundred meters, fiber-optic cables are particularly suitable for this purpose. Their low attenuation and exceptionally high data transmission rates make them ideal for inter-building cabling. Additionally, fiber-optic cables are insensitive to electromagnetic interference and provide galvanic isolation between buildings, which is another significant advantage.

Secondary cabling connects the building distributor to the downstream distributors, which are also referred to as floor or story distributors. Since cable lengths of more than 100 meters are frequently needed in this context, copper cables are often unsuitable. Fiber-optic cables, in contrast, not only support longer distances but also enable galvanic isolation of individual floors or building sections within the data cabling infrastructure.

The tertiary sector involves cabling from floor or story distributors to the connection sockets, which is why it is commonly referred to as floor cabling. In conventional structured cabling, the floor distributor connects to the terminal device sockets in a radial configuration. According to cabling standards, the distance between the distributor and the connection sockets is limited to a maximum of 90 meters, plus an additional 5 meters for patch cables at both ends. For these relatively short distances, twisted-pair copper cables are typically used.

Although the material costs for pre-assembly and splice solutions are comparable, manpower is becoming increasingly scarce and expensive at installation sites. The key advantage of pre-assembled cables lies in their fast and straightforward installation. By saving time, projects can be completed with fewer personnel, or the same team can handle multiple projects. Additionally, pre-assembled cables are factory-tested, ensuring their quality before delivery. In contrast, splice solutions or on-site installations require extensive testing with measurement equipment before acceptance, which consumes additional time.
The "data systems engineering" phase, as the final step in the implementation process, is often subject to tight time constraints. Using pre-assembled cables not only speeds up the process but can also help recover lost time, ensuring smoother project completion.
