LAN cabling systems

LAN cabling: keep it simple, but smart

Single-sided pre-assembled cabling systems

Operational flexibility, modularity and simple, fast installation coupled with guaranteed performance: that is what PerCONNECT® and PerCONNECT® EcoFlex‘IT have to offer. At the hardware level, the solutions are based on cables pre-assembled on one side, in combination with forward-looking network planning and installation by experts from Rosenberger OSI or our qualified local partners. This achieves valuable cost and time savings and significantly boosts efficiency. The solutions are used in the following areas: LAN cabling in buildings and office spaces, temporary network extensions, modular building structures.

What makes our LAN cabling products so special?


Products pre-assembled on one side for glass fiber cabling


Gel-free, reduced-diameter optical fiber cables


MTP®/MPO connecting cables as an alternative to LC


Active components can be added using PerCONNECT®EcoFlex'IT

Passive LAN network

PerCONNECT® describes the Rosenberger OSI product portfolio for passive LAN networks. By minimizing on-site installation costs, these solutions place the focus on time and cost efficiency.

  • 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 PerCONNECT®.
  • Copper technology continues to play an important role in building cabling and therefore also in the PerCONNECT® portfolio. 
  • PerCONNECT® combines copper and fiber-optic transmission technologies to create an optimum building cabling concept.

Active and passive network from a single source

PerCONNECT® EcoFlex'IT extends PerCONNECT® by adding active components and introducing an innovative overall concept that focuses on economic efficiency and flexibility both when installing completely new networks and when integrating new components in existing ones.

  • As the EcoFlex name clearly indicates, this concept places a particular emphasis on Eco (economic efficiency), and Flex (flexibility).
  • The ring-shaped, redundant FTTACP concept helps simplify project planning and permits trouble-free extensions/adaptations without interrupting business activities.
  • The efficient ACP’s also permit significant savings at the level of tertiary infrastructure (number of cables, cable ducts) and power consumption.

Any other questions?

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

What is more cost-efficient - glass fiber or copper?

At first glance, copper might seem to be the better choice due to its more economical and more flexible technology. That is why we still use low-cost, fully mature copper technology in tertiary sector building cabling – in particular to connect terminal devices. However, glass-fiber cabling brings greater peace of mind for the future because larger bandwidths can be transmitted over this medium. Forward-looking LAN cabling that brings together both aspects is available in the form of PerCONNECT® EcoFlex'IT. This combines the advantages of FTTO cabling with those of structured copper cabling in the tertiary sector. The result is great flexibility and protection for your investment.

Where does copper cabling reach its limits?

Although copper cables can also carry 40 G, this is only possible over distances of no more than 30 m in their current specification. It now seems that structured copper cabling reaches its absolute performance limit in the tertiary sector at 100 m, whereas fiber-optic cabling still has great potential for the future. For example, several hundred data signals can be transmitted in parallel over a 9-µm fiber. Using a copper cable, by contrast, it is only possible to transmit a single signal.

Redundant Ethernet cabling - what’s so special about the FTTACP concept?

With a redundantly configured cabling concept, services that operate over the network are largely unaffected by occasional downtimes or the restructuring of the network. The PerCONNECT® EcoFlex'IT Ethernet cabling solution makes use of a redundant FTTACP concept with ring configuration in order to ensure outstanding network operating reliability. What is more, the FTTACP concept permits trouble-free extensions/adaptations without interrupting business activities.

What are the advantages of pre-assembled LAN cabling systems?

All the cables, both glass fiber and copper, in our PerCONNECT® systems are pre-assembled. Pre-assembled cables are factory-measured. This means that all the fitter has to do on site is lay and connect them, creating a genuine plug & play installation. As a result, up to 50% of the on-site installation time can be saved depending on the project, thereby cutting project completion time – a highly valuable commodity in today’s world.
