CAT6 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 (CAT6 standard) and are backwards compatible with CAT5e and CAT5 cables. They are produced with snaggles (boots), which prevent the connector from being damaged when you install the cable in tight spaces. Furthermore, this cable is manufactured with shielding, which protects against electromagnetic interference (EMI). EMI can cause crosstalk between circuits, resulting in degradation of data, increased errors, and slower transmission rates. By using this shielded cable, you can avoid these problems.
