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
of "permanent link" (the solid copper wire hidden behind walls). network cable length
In older half-duplex Ethernet, the length was limited so that a computer at one end could detect a "collision" (two devices talking at once) before it finished sending its data. The length of a network cable is not
