Why each option
BNC (Bayonet Neill-Concelman) connectors are the standard connector type used to terminate coaxial copper cable in networking and video applications.
The BNC connector is specifically designed for coaxial cable, using a bayonet-style locking mechanism that secures the connector with a quarter-turn twist. It was widely used in 10Base2 (Thinnet) Ethernet networks and is still used in video and RF applications today. Its design accommodates the single center conductor and surrounding shield that characterize coaxial cable.
DB-9 is a D-sub serial connector used for RS-232 serial communications, not for coaxial copper cable.
RJ-11 is a modular connector used with twisted-pair telephone wiring, not coaxial cable.
ST (Straight Tip) is a fiber optic connector and is not compatible with or used for copper coaxial cable.
