The length of a network cable is not just a physical measurement; it is a fundamental constraint that dictates the speed and reliability of the digital world. While often invisible to the average user, the "100-meter rule" of Ethernet cabling is a masterpiece of engineering compromise between physics and performance. The Standard: The 100-Meter Horizon
For most modern copper-based Ethernet networks, the standard maximum length for a single cable run is 100 meters (approx. 328 feet) . This distance is rarely a single continuous wire. In professional installations, it is typically divided into: network cable length
of "permanent link" (the solid copper wire hidden behind walls). The length of a network cable is not
