The 10Base-2 standard describes an Ethernet variant with a thin coaxial cable, the RG-58 cable. It arose from the desire for an alternative to the bulky Yellow Cable of the 10Base-5 version. This version is also called Cheapernet or Thinnet.
The data rate is 10 Mbit/s and the topology is a bus topology as with 10Base-5, but only of the max. length 185 m per LAN segment without repeater. Up to 30 stations can be connected to one LAN segment. In contrast to 10Base-5, a Cheapernet MAU is usually located completely on the adapter card, which must then have a BNC-T connector or a BNC socket for connection to the LAN segment.
