Frequently Asked Questions
How thin is this flat Ethernet cable, and will it fit under a door?
The cable is 2.7mm thick. The listing says it is designed to run under carpets and doors and along baseboards and walls. Whether it clears your door depends on the gap under that door.
Is a Cat8 cable faster than the Cat6 I already have?
The cable is rated for up to 40Gbps and 2000MHz, which is above Cat5e, Cat6 and Cat7 ratings. Your real speed is capped by your router, switch, network card and internet plan, so the extra headroom only helps if that hardware supports higher speeds.
Will the plugs fit into a router with closely spaced ports?
Yes, that is what they are designed for. The cable uses narrow RJ45 plug molds, so several cables can sit side by side in routers, Ethernet switches and PCs without the plug housings pushing against each other.
Is the cable shielded against interference?
Yes. It is an SFTP cable with 4 pairs of foil-shielded twisted pair wires. The shielding provides EMI and RFI protection and reduces crosstalk, which helps in offices, data centers and electrically noisy rooms.
Can I use this cable outdoors?
The listing says it is for indoor and outdoor use, but it gives no UV, weatherproofing or direct-burial rating. For permanent outdoor or underground runs, check the manufacturer's listing for current specifications before you install it.
