6.3.1.5.2 Wiring
For the maximum possible cable lengths within an Ethernet network, various factors have to
be taken into account. T
wisted pair cables (TP cables) are used as transmission medium for
10 Mbit/s Ethernet (10Base-T) as well as for 100 Mbit/s (Fast) Ethernet (100Base-TX). For a
transmission rate of 10 Mbit/s, cables of at least category 3 (IEA/TIA 568-A-5 Cat3) or class C
(according to European standards) are allowed. For fast Ethernet with a transmission rate of
100 Mbit/s, cables of category 5 (Cat5) or class D or higher have to be used. The maximum
length of a segment, which is the maximum distance between two network components, is
restricted to 100 m due to the electric properties of the cable.
Furthermore, the length restriction for one collision domain has to be observed. A collision
domain is the area within a network which can be affected by a possibly occurring collision
(i.e. the area the collision can propagate over). This, however, only applies if the components
operate in half-duplex mode since the CSMA/CD access method is only used in this mode. If
the components operate in full-duplex mode, no collisions can occur. Reliable operation of the
collision detection method is important, which means that it has to be able to detect possible
