CAT5e cables provide a convenient and reliable connection from a network device, such as a switch, modem, or router, to another device or to the overall infrastructure via a patch panel, keystone jack, or wall outlet. These cables are also commonly used in small office and home networks as well as in entertainment applications. They are tested up to 100 MHz (CAT5e standard) and are backward compatible with CAT5 cables. They are manufactured with a locking protection mechanism that prevents the connector from being damaged when installing the cable in tight spaces.
