10BASE2 (also known as cheapernet, thin ethernet, thinnet or thinwire) is a variant of Ethernet that uses thin coaxial cable (RG-58 or similar, as opposed to the thicker RG-8 cable used in 10BASE5 networks), terminated with BNC connectors. For many years this was the dominant 10 Mbit/s Ethernet standard, but due to the immense demand for high speed networking, the low cost of Category 5 Ethernet cable, and the popularity of 802.11 wireless networks, both 10BASE2 and 10BASE5 have become almost obsolete. 10BASE2 Cable showing BNC end connector. ... 10BASE2 Cable showing BNC end connector. ... 10BASE2 cable with t-piece connector. ... 10BASE2 cable with t-piece connector. ... 10BASE2 Cable end terminator. ... 10BASE2 Cable end terminator. ...

In a 10BASE2 network, each segment of cable is connected to the transceiver (which is usually built into the network adaptor) using a BNC T-connector, with one segment connected to each arm of the T. At the physical end of the network a 50 Ohm terminator is required. This is most commonly connected directly to the T-connector on a workstation though it does not technically have to be.

When wiring a 10BASE2 network, special care has to be taken to ensure that cables are properly connected to all T-connectors, and appropriate terminators are installed. One, and only one, terminator must be connected to ground via a ground wire. Bad contacts or shorts are especially difficult to diagnose, though a time-domain reflectometer will find most problems quickly. A failure at any point of the network cabling tends to prevent all communications. For this reason, 10BASE2 networks could be difficult to maintain and were often replaced by 10BASE-T networks, which (provided category 3 cable or better was used) also provided a good upgrade path to 100BASE-TX. An alternative reliable connection has been established by the introduction of EAD-sockets. It has been suggested that Ground conductor be merged into this article or section. ...

10BASE2 networks cannot generally be extended without breaking service temporarily for existing users and the presence of many joints in the cable also makes them very vulnerable to accidental or malicious disruption. There were proprietary wallport/cable systems that claimed to avoid these problems (e.g. SaferTap) but these never became widespread, possibly due to a lack of standardisation.

10BASE2 systems do have a number of advantages over 10BASE-T. They do not need the 10BASE-T hub, so the hardware cost is very cheap, and wiring can be particularly easy since only a single wire run is needed, which can be sourced from the nearest computer. These characteristics mean that 10BASE2 is ideal for a small network of two or three machines, perhaps in a home where easily concealed wiring may be an advantage. For a larger complex office network the difficulties of tracing poor connections make it impractical. Unfortunately for 10BASE2, by the time multiple home computer networks became common, the format had already been practically superceeded.

The name 10BASE2 is derived from several characteristics of the physical medium. The 10 comes from the maximum transmission speed of 10 Mbit/s (millions of bits per second). The BASE stands for baseband signalling, and the 2 represents a rounded up shorthand for the maximum segment length of 185 meters (607 feet). A megabit per second (Mbps or Mbit/s or Mb/s) is a unit of data transmission equal to 1,024 kilobits per second or 1048576 bits per second. ... This article is about the unit of information. ...
