Maximum Ethernet cable length: What can it be?

Maximum length of cable ethernetWhich one could it be?
The golden rule for standard copper Ethernet cables (such as Cat5e, Cat6 and cat6a) is 100 meters (328 feet). This maximum length includes the entire channel: the main cable run plus any shorter patch cables at each end.

Why the 100m limit?
Beyond this distance, electrical signals traveling through copper cables weaken significantly due to attenuation. Interference (crosstalk) and signal synchronization problems also become problematic. Exceeding 100 meters typically results in slow speeds, intermittent connections, or complete failures.

Need to go further? You have options:

Network switches/hubs: Placing an active device, such as a switch or hub, before the 100m mark resets the distance counter. This allows you to daisy-chain segments (each

Ethernet extenders: These specialized devices convert the signal for transmission over longer distances, sometimes using different cabling, such as coaxial cable or DSL lines, which can reach kilometers. Fiber optic cables: For very long spans (hundreds of meters or even kilometers) and superior performance, fiber optic cables are the ideal solution, although they require compatible transceivers at each end.
