What is the maximum length for a CAT 5e Ethernet cable?

The maximum length for a CAT 5e Ethernet cable is 100 meters. This specification ensures reliable performance for network communications, allowing for data transmission at speeds up to 1 Gbps over distances that are common in networking environments. The 100-meter limit includes all cabling and any patch cables used in the connection, from the device to the switch or router.

Using a CAT 5e cable beyond this 100-meter maximum could lead to signal degradation and increased error rates, which would adversely affect network performance. This limit is a critical factor in network design and installation, ensuring that the infrastructure supports the required data rates without compromising connectivity.
