2.1
10/100BASE-TX (RJ-45) PORTS
The cable used to connect a 10/100Base-Tx port should be an unshielded twisted 4 pair
category five cable (UTP-5) with 8-pin RJ-45 connectors. The cable length should not be
more than 100 m.
The UTP-5 cable is made up of eight copper wires that form the four twisted pairs, covered
in different coloured insulating material. FIGURE 13 shows the colour of the wires that
make up each one of the pairs, according to ANSI/TIA/EIA-568-A standard.
