10base2 Definition

(computing) An early thin form of Ethernet cable.

The IEEE standard (1986) for relatively thin coaxial cable in support of Ethernet transmission. Also known as ThinNet (Thin EtherNet), 10Base2 translates to 10 Mbps (theoretical transmission rate), Baseband (one transmission at a time over a single, shared channel), and 200 meters maximum segment length (actually 185 meters, rounded up). The thinner cable is less costly to acquire and deploy than earlier 10Base5, although its performance is less in terms of transmission distance due to increased attenuation. See also 10Base2, attenuation, baseband, channel, coaxial cable, Ethernet, IEEE, and transmission rate.
