EAD cable

from Wikipedia, the free encyclopedia
EAD cable

An EAD cable is a connecting cord in computer networks in coaxial technology ( 10BASE2 ) a computer with a matching Ethernet socket (EAD) to connect.

Although the EAD cable looks like a simple connection on the outside, it works like a T-piece ; it actually consists of two coaxial cables and thus forms a loop. This increases the cable length of the network segment by twice the length of the cable with each plugged-in EAD cable.

Two computers can be connected to most EADs using these cables. When plugging in, there is only a very short interruption of the network segment, so that, in contrast to the use of T-pieces, there are normally no faults even during operation.

Since around the 2000s, network installations have been carried out almost exclusively using twisted-pair technology, and existing installations using coaxial technology have largely been converted, so that the EAD cable is of little importance today.

Wrong word "BNC cable"

The term “BNC cable” is often mistakenly used to refer to Ethernet cables with BNC connectors .

BNC is only called the round plug, the cable is a different coaxial cable depending on the application (e.g. RG-58 for Ethernet with 50 Ω resistance, RG-59 as video / antenna cable with 75 Ω or as RG-62 with 93 Ω at ARCNet ).

The roughly rectangular plug for the wall socket is a TAE plug with the coding "E".
