CAT6 cables enables a convenient and reliable connection from one network device. such as switch. modem or router. to another or to the infrastructure at large through a patch panel. keystone jack or wall outlet. This cable are also used a lot in small office and home network and entertainment applications. These cables are tested up to 250Mhz (CAT6 standard) and are backwards compatible with CAT5e and CAT5 cables. They are produced with snaggles (boot). which prevents the connector do be damaged when you install the cable through an installation with very less space. Furthermore this cable is manufactured with shielding. This protects against both EMI (electromagnetic interference). EMI can cause crosstalk between circuits. resulting in degradation of data. increased errors and slower transmission rates. but by using this shielded cable you will avoid this problem.
