Difference between cat7 and cat8
The main differences between CAT7 and CAT8 cables are transmission speed, frequency range, and maximum transmission distance. 12
Transmission speed and frequency range: CAT8 cables support transmission speeds of up to 40Gbps and a frequency range of 2000MHz, which makes it ideal for applications that require extremely high bandwidth, such as data centers and high-end gaming servers. In contrast, CAT7 cables have a transmission speed of 10Gbps and a frequency range of 600MHz, and are mainly suitable for 10G networks.
Maximum transmission distance: The maximum transmission distance of CAT8 cables is 30 meters, which is suitable for short-distance high-bandwidth connections. The maximum transmission distance of CAT7 cables is also 100 meters, which is suitable for longer network cabling needs.
Shielding technology: Both use shielding technology to reduce electromagnetic interference, but CAT8 uses a more advanced double-layer shielding technology, which provides a stronger shielding effect, especially suitable for environments that require high confidentiality or shielding from electromagnetic interference.
In general, choosing CAT7 or CAT8 network cable depends on the specific application requirements. If ultra-high speed and short-distance connection are required, CAT8 is a better choice; if longer wiring is required and the speed requirement is not so high, CAT7 may be more suitable.
