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 |
| Cat6a | Up to10Gb | 500MHz | 65m | 100m |
| Cat7 | Up to 10Gb | 600MHz | 65m | 100m |
| Cat7a* | Up to 40Gb | 1000Mhz | 65m | 50m |
| Cat8.1* | Up to 25Gb | 2GHz | – | 30m |
| Cat8.2* | Up to 40Gb | 2GHz | – | 30m |
*Cat7a is not recognised by the TIA/EIA and requires TERA or GG45 connectors
*Cat8.1 is Cat8 Class 1, which is U/FTP or F/UTP and an RJ45 connector
*Cat8.2 is Cat8 Class 2, which is F/FTP or S/FTP and requires TERA or GG45 connectors
Universal Networks supplies both pre-assembled and un-terminated UTP and STP copper networking cables.
