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. of "permanent link" (the solid copper wire hidden

Physics isn't always constant. Several factors can shorten your effective cable length: Physics isn't always constant

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
