What is the maximum length for a standard Ethernet cable?

The maximum length for a standard Ethernet cable, specifically for twisted-pair cables like Cat 5e or Cat 6, is 100 meters. This limit is set to ensure signal integrity and minimize attenuation, which can lead to data loss over longer distances. Beyond this length, the quality of the signal can degrade significantly, resulting in slower data transmission speeds and potential connectivity issues. For typical Ethernet installations such as those used in local area networks (LANs), adhering to this standard length is crucial for optimal performance. This specification applies to both horizontal cabling (from the wall outlet to the network switch) and the vertical cabling (between floors, connecting different network segments).
