Cable length
For the maximum possible cable lengths within an Ethernet network, various factors have to
restrictions
be taken into account. Twisted 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
