What is the maximum channel length for Ethernet copper cabling?

The main idea is how far a copper Ethernet signal can travel while still meeting the timing and signal quality the standards require. For common copper Ethernet standards (like 10BASE-T, 100BASE-TX, and 1000BASE-T), the total length from one device to the other—including any patch cables—is limited to one hundred meters. This keeps attenuation, noise, and propagation delay within the bounds that the receiver and the network timing rely on, ensuring reliable communication and proper collision detection where applicable. If you go beyond this distance, the signal can become too weak or distorted for correct decoding, which is why copper cabling has this explicit limit. Shorter lengths are fine, but the maximum you can reliably run on copper is one hundred meters. Longer distances would require fiber or repeating devices.
