Choose a Cat Ethernet cable suitable for your network needs, considering speed and distance requirements.
I plan to run my cable through the wall from my PC to the router. It will likely be around 30 meters, so I’ll start with a 30m Cat5e and hope it works. My internet speed should be about 100 MB/s. Should I upgrade to Cat6? Cat7 is essentially Cat6 with added shielding if I recall correctly. Shielding becomes necessary in certain situations, like when dealing with interference or in environments with many electronic devices nearby.
Shielding becomes essential when working near high voltage power cables or handling large amounts of Ethernet cables simultaneously. This refers to very high voltage systems, not just ordinary residential wiring. Cat5e or Cat6 works well for 2.5Gbps and 5Gbps over up to 100 meters, while Cat6 supports up to 10Gbps over about 35-50 meters. Beyond 50 meters for 10Gbps, consider using Cat6a. Cat7 is generally misleading since it doesn't match the required TERA connectors and instead uses 8p8c connectors.
I’d upgrade from cat5e to cat6 mainly because of the length. Cat6 works well up to 100 meters, beyond that the signal weakens and you’ll face connectivity issues. It also helps prepare for future internet needs. Shielding the cable stops signal loss and interference from outside sources—especially strong appliances like big air conditioners, elevators, or printers.
All Ethernet types perform well up to 100 meters. The specific cabling category sets the upper speed limit at that range. No cable type is approved for distances beyond 100 meters due to signal stability requirements. Beyond this point, reliability becomes uncertain—connections may fail, packets could corrupt, or performance might be inconsistent.
Thanks for sharing the details—this info is likely to be useful for Cat6 Cable!
Yep, the exception comes when using Cat6 at 10Gbps, where you usually reach around 30-50 meters. The official spec says 55 meters for 10Gbps, while 5Gbps and below cover up to 100 meters. I haven’t seen it go that far; most setups stick with Cat6a at that point.
