Cat 6 cables enable a convenient and reliable connection from one network device, such as a switch, modem, or router, to another or to the infrastructure at large through a patch panel, keystone jack, or wall outlet. These cables are also commonly used in small office and home network and entertainment applications. They are tested up to 250 MHz (Cat 6 standard) and are backwards compatible with Cat 5e and Cat 5 cables. They are produced with snaggles (boots), which prevent the connector from being damaged when installing the cable in tight spaces.
