  10BASE2 - Wikipedia, the free encyclopedia
10BASE2 (also known as cheapernet or thinnet) 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.
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.
For this reason, 10base2 networks could be difficult to maintain and were often replaced by 10BASE-T networks, which (provided category 5 cable was used) also provided a good upgrade path to 100BASE-TX.

 Networking - 10Base2 "ThinnNet" Ethernet
The 10Base2 ethernet standard was the first major revision to the original standard for ethernet cabling and termination, which was called 10Base5 (although 10Base5 still exists in a few places, it is obsolete, and there is none at Penn).
The 10Base2 standard allowed for cabling by means of less expensive 50 ohm coaxial cables (such as RG-58, commonly used in CB radio, for example) and BNC connectors.
Originally, 10Base2 was designed for use with RG-58, an industry-standard coaxial communications cable that had been in use for many years, particularly among amateur "ham" and CB radio operators.

 Networking Explained - installing a network in your home or small office
The "2" in 10Base2 indicates the maximum segment length in hundreds of metres –; the maximum aggregate length of cables you can use, with up to 30 computers connected, before you have to start using routers, bridges or switches, of which more later.
A 10Base2 segment (a segment, in this case, is a network with no bridges or switches or other fancy devices in it) contains two or more computers, each with a network card (NIC) fitted with a T-piece which accepts two network cables, or a network cable and a 50 ohm terminating resistor.
The 10Base2 spec says the network "may" be grounded in one (and ONLY one) place, and doing this may reduce network errors.

 Support Tips for Hubs
Each unit in a 10BASE2 network is attached to the network in a "daisy chain", that is, each unit is wired in serial with the previous unit, using 10BASE2 compatible "T-Connectors".
The 10BASE2 devices are plugged into the 10BASE2 BNC connector on the back of the hub(s), and the 10BASE-T devices are plugged into the RJ-45 connectors on the back of the hub.
If you are using the 10BASE2 to connect the hubs, or other devices to a hub, and a problem develops involving the cabling, network connections or elsewhere in the 10BASE2 Ethernet network, the COAX LED will come on to indicate that you have a problem.

10base2 operates essentially on the same type of coax cabling your TV is connected to (if you have cable TV, anyway).
A 10base2 network is basically a large bus with segments of coax connected together with T-connectors, which connect to the computers participating in the network.
If you're only connecting two or three home computers, it may be more economical for you to install 10base2, as the bandwidth is adequate in most cases, and a hub is not required.

 10BASE2
The 10BASE2 cabling topology (Thinnet) generally uses the on-board transceiver of the network interface card to translate the signals to and from the rest of the network.
The main advantage of using 10BASE2 in your network is cost.
When any given cable segment on the network doesn’t have to be run further than 185 meters (607 feet), 10BASE2 is often the cheapest network cabling option.

Each segment of cable is connected to the workstation using a T-piece, with one segment coming in on each arm of the T. At the physical end of the network, the T-piece attached to the workstation would require a 50-ohm terminator.

The spacing between stations is not critical with the 10Base2 specification, but it does require that a minimum of 0.5 meters of cable separate any two stations.
Each end of a 10Base2 coaxial segment must be terminated with a BNC 50-ohm terminator.
10Base2 Disadvantages: 1) daisy chained segments are unreliable and difficult to troubleshoot, and 2) daisy chained segments can be difficult to route in an office environment, and 3) the coaxial medium does not support higher speed Ethernet standards.

 10BASE2   (Site not responding. Last check: 2007-10-01)
When wiring a 10base2 network, special care has to be taken that cables should be properly connected to all T-pieces, and appropriate terminators should be plugged in.
For this reason, 10base2 networks were a bit uneasy to maintain and were often replaced by 10baseT networks, which had a good upgrade path to 100baseTX.
The BASE stands for baseband signalling, and the 2 represents a rounded up shorthand for the maximum segment length of 185 metres.

 Ethernet - Wikipedia, the free encyclopedia
Ethernet was originally based on the idea of computers communicating over a shared coaxial cable acting as a broadcast transmission medium.
People recognized the advantages of cabling in a star topology, primarily that only faults at the star point will result in a badly partitioned network, and network vendors started creating repeaters having multiple ports, thus reducing the number of repeaters required at the star point; multiport Ethernet repeaters became known as "hubs".
Later, 10BASE2 Ethernet used thinner coaxial cable (with BNC connectors) as the shared CSMA/CD medium.

 Practically Networked Forums - connect two hubs via BNC and 10Base2 connection?
The hub has a BNC outlet for using 10base2 cable which I have used to connect to home number 2 (I used this due to the excessive distance of about 600 feet).
In house number two I have simply fed all the computers with the 10 base 2 configuration (one computer to the next with the "T" connection and a 50 ohm terminator at the end of the line).
My question is, can I simply hook up another hub to the 10Base2 wiring in house 2 and then use 10BaseT wiring from there for house number 2 (changing the existing wiring from house to house is not an option).

 Services Provided By SAS Network Services
Currently, all 10Base2 connections in Bennett Hall are active, while each new 10BaseT-only box installed as part of the wiring project has at least one active connection.
This last example is particularly important, as over the years one of the most persistent network problems has been the presence of inappropriate cabling that, while the cable and connectors may seem to be the same, often does not meet proper specifications.
Requests are sometimes made for SAS-NS to run 10Base2 "daisy-chains" or extended 10BaseT cables from an outlet box in one room into another room for the purpose of connecting equipment in multiple rooms to one outlet.
