Recommended Cables and Cable Specifications
There are various grades of voice-quality and data-quality cables available.
These can appear to be similar externally, although their high-speed data
transmission characteristics are radically different. The identification problem
is made worse by some suppliers selling voice-quality cables as data-quality
cables.
If voice-quality cables are used in a 100Base-TX network system, data
movement may be slow, collision-prone or non-existent. In addition, interface
LEDs will usually indicate a valid link in such cases.
Table 3 provides an overview of IEEE 802.3 and 802.3u cabling specifications
for 10Base-T and 100Base-TX network configurations using twisted-pair cable.
