Cat7 Cable
Cat7 cables are designed for incredibly fast and reliable connections. Up to 600 MHz of bandwidth is supported, and depending on the distance, it can give you rates of 10 to 40 Gbps.
Heavy shielding is one of Cat7’s best qualities; each wire inside the main protective wire is shielded separately to stop EMI and RFI from interfering with data transmission via the cable.
Even in places with a lot of electronic devices or numerous cables running side by side, this Cat7 protects signals from interference when you’re using the internet.
Because of its thickness, this may be more expensive and more difficult for you to install. And this is not made for you if you are looking for home use, because it works better in heavy setup environments.
