The distances achievable using the different categories of Copper cables are illustrated in the following table. Stranded and Solid are characteristics of the conductors and affect the performance.
The figures for Stranded cables are approximate and vary considerably with the quality of the cable:
|Ratified Standard||Speed Achievable||Transmission Frequency||Distance (Stranded)||Distance (Solid)|
|Cat5e||Up to 1Gb||100MHz||65m||100m|
|Cat6||Up to 1Gb||250MHz||65m||100m|
|Cat7||Up to 10Gb||600MHz||65m||100m|
|Cat7a||Up to 40Gb||1000Mhz||65m||TBA|
|Cat8*||Up to 40Gb||1.6GHz – 2GHz||30m|
* Cat8 is yet to be a ratified standard
