Primary cabling - Site cabling
The primary area is designated as campus cabling or site cabling. The primary area implements
the joint cabling of individual buildings. The primary area includes large distances, high
transmission rates as well as a minimum number of stations.
In most cases is glass fibre cable (50 µm) with a maxim length of 1,500 m used. Normally these
are glass fibre cables with multi-mode fibres or also single-mode cables in case of greater
distances. Sometimes also copper cables are used for smaller distances.
The primary area should fundamentally be planned in greater detail. The transmission medium
should, with regard to the transmission speed, be open upwards. This equally applies to the
transmission system used. As a rule of thumb, a 50 percent reserve applies to the current
requirement of the investment.
Secondary cabling - building cabling
The secondary area is designated as building cabling or rising area cabling. The secondary
area implements the joint cabling of individual floors or storeys within a building. Here the
preferred use is glass fibre cables (50 µm) or copper cables with a maximum length of 500 m.
Tertiary cabling - floor cabling
The tertiary area is designated as floor cabling. The tertiary area implements the cabling of floor
or storey distributors to the connection sockets. While a network cabinet with a patch field is
located in the storey distributor, the cable at the workplace of the user leads to a connecting
socket on the wall, to a cable duct or a floor tank with outlet.
Twisted pair cables are used for these relatively short distances whose length is limited to a
total of 100 m (90 m plus 2 x 5 m connecting cable). Also glass fibre cables (62.5 µm) are used
as an alternative.
