What is the maximum length allowed for a standard Ethernet cable?

The maximum length allowed for a standard Ethernet cable is 100 meters. This specification applies primarily to twisted-pair cabling, such as Cat5e or Cat6, commonly used for Ethernet connections in local area networks (LANs). The length limitation ensures that data transmitted over the cable maintains signal integrity and minimizes attenuation, which can cause data loss or degradation in performance.

Beyond this distance, the signal strength can weaken significantly, resulting in potential data corruption or connectivity issues. Thus, adhering to the 100-meter maximum ensures reliable communication and optimal performance in Ethernet networks.
