and 1000BASE-T. In 2003, the IEEE 802.3 working group deprecated 10BASE5 for new installations.

Name origination

The name 10BASE5 is derived from several characteristics of the physical medium. The 10 refers to its transmission speed of 10 Mbit/s. The BASE is short for baseband signaling (as opposed to broadband), and the 5 stands for the maximum segment length of 500 m.
