Three Trends Challenge the LAN

High-frequency transmission for 10 to 40 Gigabit/s, constant remote power supply for Power over Ethernet and comprehensive Ethernet/IP supply is challenging the LAN. LAN cabling, therefore, has to fulfill new requirements.

Structured cabling must achieve more

Structured cabling remains an important basis for local data networks even in the era of digitization and mobility. But in the future, it is going to have to do more than just link workstations. R&M points out the challenges for the LAN, planners and installers (see also Connections No. 54).Cat. 6 shielded

The LAN is essentially influenced by three trends. Where higher bandwidths, constant remote power supply, and ubiquitous availability are introduced in the course of digitalization, some of the framework conditions are changing dramatically.

First example: higher bandwidth

10GBase-T reacts very sensitively to external noise. There is no more headroom. Therefore, the installation must be absolutely standard-compliant.

But development doesn’t stop here. In the LAN there will be a protocol mix in the future. In addition to 2.5, 5 and 10GBase-T, 25 and 40GBase-T are coming onto the market. According to R&M’s current estimates, 25GBase-T may be the long-awaited next evolutionary step in the LAN area.

The new category 8.1, specified for transmission frequencies up to 2000 MHz, is recommended as a connection solution for 40- and 25GBase-T. R&M will launch a Cat. 8.1 system as soon as all framework conditions for 25GBase-T have been established.

Second example: Power over Ethernet (PoE)

4PPoEPoE could develop into a key technology for the Internet of Things (IoT). The third PoE generation even uses all four wire pairs (4PPoE) and will support outputs of up to 90 watts with currents of 1 ampere per wire pair to power many terminals and LED light sources.

Some new applications, however, require electrical power around the clock, e.g. smart lighting and digital signage. The cables and cable bundles heat up in continuous PoE operation as a result of the electrical resistance. The risks in planning, installing and operating the network must not be disregarded.

Third example: All over IP and consolidation

Applications and infrastructures which to date have been separate are increasingly being consolidated. LAN cabling is to provide full Ethernet / IP services for building automation throughout the building, turning the LAN into a multifunctional LAN.

In this context, it is important for planners that large areas and spaces can be efficiently divided into zones using a honeycomb structure. Service outlets (SO) from the center of these zones and serve as connection points for the IP-supported functions. The ceiling is often seen as the best place for service outlets. This phenomenon is referred to as digital ceiling. R&M has prepared a suitable Digital Ceiling program.
