Observe special environments such as mining, petrochemicals,
tunnels, pipelines etc. The MICE classication is not valid for these.
2.6 Power capability of the cabling
Both IEC 11801 and EN 50173 contain a classication of symmetric copper
cabling. To date, classes A-F have been described. As a rule: the higher the class
the better the quality of transmission of the cable.
General transmission path classes for industrial applications
Class D – specied up to 100 MHz;
frequently used transmission route with capacity for 100 Mbps or 1,000 Mbps
Klasse E – specied up to 250 MHz;
Transmission routes with capacity for 100 Mbps, 1,000Mbps and additional
capacity reserves
Klasse E
A
– specied up to 500 MHz;
Transmission routes with capacity for 100 Mbps, 1,000Mbps and 10 Gbps
