CAT6 provides a comprehensive attenuation to crosstalk ratio of at least 200MHz and an overall bandwidth of 250MHz. CAT7 can provide at least 500MHz comprehensive attenuation to crosstalk ratio and 600MHz overall bandwidth.
The performance improvement of the CAT7 cabling is very obvious, which makes the transmission capacity and attenuation level of the copper cable medium close to the performance of the optical fiber.
CAT6 cabling system can use both UTP and STP, while CAT7 cabling system is only based on shielded cable. In the CAT7 network cables, each pair of wires has a shielding layer, and four pairs of wires together have a common large shielding layer.
Non-RJ type CAT7 adopts double shielded cable, which can meet the needs of areas where shielded twisted pair system is dominant.
Differences in capacity
The parameters of CAT7 require that all pairs of wires provide at least 60dB of integrated near-end winding at 600MHz. However, the CAT5e only requires 43db in 100MHz. The value of CAT6 at 250MHz is 46db.
