10Base-36

10Base-36

10Base-36 is a type of physical cabling defined in the IEEE 802.3 (Ethernet) standard for broadband application. Although Ethernet is inherently a baseband system, 10Base-36 specifies the use of a 10-megahertz signal on each channel within a 75-ohm coaxial broadband cable so that bandwidth is effectively expanded. Each channel requires 3 pairs of wires in the coaxial cable. Baseband differential phase-shift keying (PSK) is used to modulate the signal on each channel. Each channel has a transmission speed of 10 Mbps. The cable can extend for up to 3,600 meters.

In addition to 10Base-36, 10 megabit Ethernet can be implemented with these media types:

10BASE-2 (Thinwire coaxial cable with a maximum segment length of 185 meters)
10BASE-5 (Thickwire coaxial cable with a maximum segment length of 500 meters)
10BASE-F (optical fiber cable)
10BASE-T (ordinary telephone twisted pair wire)

This designation is an Institute of Electrical and Electronics Engineers (IEEE) shorthand identifier. The "10" in the media type designation refers to the transmission speed of 10 Mbps. The "BASE" refers to baseband signalling, which means that only Ethernet signals are carried on the medium (or, with 10Base-36, on a single channel). The "T" represents twisted-pair; the "F" represents fiber optic cable; and the "2", "5", and "36" refer to the coaxial cable segment length (the 185 meter length has been rounded up to "2" for 200).
