Thinnet Connectors
The most common connectors for RG-58 cabling on thinnet networks are barrel connectors, T connectors, and terminators. These connectors are known as British Naval Connectors or just BNC connectors.
A barrel connector connects two sections of coaxial cabling. A BNC-T connector fits on the end of the network interface card and connects a station to two sections of RG-58 cabling.
Terminators are placed on each end of a thinnet network segment to absorb signals as they reach the end of the wire.
This absorption keeps the signals from reflecting and preventing other stations from transmitting.
