Network Cable Length Link

of "permanent link" (the solid copper wire hidden behind walls).

As electricity travels through copper, it meets resistance, causing the signal to lose energy and "fade". network cable length

Exceeding this limit doesn't just result in a slightly slower connection; it can lead to , where the electrical signal weakens so much that the receiving device can no longer distinguish data from background noise. Why 100 Meters? The Physics of the Limit The 100-meter limit exists for three primary reasons: of "permanent link" (the solid copper wire hidden

Longer wires have more resistance , leading to larger voltage drops. This is especially critical for Power over Ethernet (PoE) , where a cable too long may not deliver enough power to run a camera or Wi-Fi access point. Environmental Variables: When 100m is Too Long Why 100 Meters

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.
