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.
