N10-005 · Question #518

Which of the following is a common connector used on a coaxial cable?

The correct answer is C. BNC. The BNC (Bayonet Neill-Concelman) connector is the standard connector type used with coaxial cables in networking and video applications. Other connector types listed are associated with different cable media entirely.

Why each option

The BNC (Bayonet Neill-Concelman) connector is the standard connector type used with coaxial cables in networking and video applications. Other connector types listed are associated with different cable media entirely.

ARJ-45

RJ-45 is an 8-pin modular connector used with twisted-pair Ethernet cables (Cat5e, Cat6), not coaxial cable.

BDB-25

DB-25 is a 25-pin D-subminiature connector historically used for RS-232 serial and parallel port connections, not coaxial cable.

CBNCCorrect

The BNC connector uses a bayonet-style twist-and-lock coupling mechanism and is designed specifically for coaxial cable, providing a secure connection with proper impedance matching. It was widely used in 10BASE2 (Thinnet) Ethernet networks and is still common in video and RF applications.

DLC

LC (Lucent Connector) is a small form-factor fiber optic connector used with fiber optic cables, not coaxial cable.
