100Base-TX Cable

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.
Category 5 is required cabling for use with 100Base-TX connections. Using any
other category for a 100Base-TX connection may have high error rates and may
not have the capacity to transmit data.
