What is the maximum supported link length for a 100BASE-TX Fast Ethernet connection using Cat 5 cable?

A 100BASE-TX Fast Ethernet connection using Category 5 (Cat 5) cable can support a maximum link length of 100 meters. This specification is crucial for maintaining the integrity of the signal over distance, ensuring that data transmission remains reliable while minimizing the potential for packet loss or signal degradation.

In practical terms, this means that installations using 100BASE-TX can stretch for up to 100 meters between network devices, such as switches and computers, without needing signal boosters or repeaters. This length accounts for both horizontal cabling and patch cords used within a network setup. Staying within this length ensures compliance with standards set by the Institute of Electrical and Electronics Engineers (IEEE) for Fast Ethernet technology, providing a balance between performance and usability in network design.
