What is the maximum cable length supported by Cat 5 for 100BASE-TX and 1000BASE-T connections?

The maximum cable length supported by Category 5 (Cat 5) cable for 100BASE-TX and 1000BASE-T connections is indeed 100 meters. This standard is critical for ensuring reliable data transmission in Ethernet networks.

For 100BASE-TX, which operates at 100 Mbps, the 100-meter length provides sufficient distance for transmission across various network topologies while maintaining signal integrity and minimal bit errors.

In the case of 1000BASE-T, which supports gigabit Ethernet at a rate of 1 Gbps, the same 100-meter limit applies. This requirement ensures that data can be sent and received effectively without degradation, given the higher frequency and data rate compared to 100BASE-TX.

Understanding these distance limitations is essential for network design and implementation, as exceeding the maximum length can lead to increased attenuation and degradation of the signal.
