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
As electricity travels through copper, it meets resistance, causing the signal to lose energy and "fade". network cable length
of "permanent link" (the solid copper wire hidden behind walls). Longer wires have more resistance , leading to
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
