10BROAD36 is an obsolete computer network standard in the Ethernet family. It was developed during the 1980s and specified in IEEE 802.3b-1985. The Institute of Electrical and Electronics Engineers standards committee IEEE 802 published the standard that was ratified in 1985 as an additional section 11 to the base Ethernet standard.[1] It was also issued as ISO/IEC 8802-3 in 1989.[2]
The standard supports 10 Mbit/s Ethernet signals over standard 75 ohm cable television (CATV) cable over a 3600-meter range. 10BROAD36 modulates its data onto a higher frequency carrier signal, much as an audio signal would modulate a carrier signal to be transmitted in a radio station. In telecommunications engineering, this is a broadband signaling technique.[a] Broadband provides several advantages over the baseband signal used, for instance in 10BASE5. Range is greatly extended (3,600 m (11,800 ft), versus 500 m (1,600 ft) for 10BASE5), and multiple signals can be carried on the same cable. 10BROAD36 can even share a cable with standard television channels.
