Bayonet Neill–Concelman
Full Form of BNC
What is BNC?
BNC (Bayonet Neill–Concelman) is a type of coaxial connector used for terminating coaxial cables. Named after its inventors, Paul Neill and Carl Concelman, the connector features a bayonet-style coupling mechanism that allows quick twist-on connection and disconnection without tools. In India, BNC connectors are commonly deployed in CCTV camera installations, telecommunications equipment, radio frequency (RF) testing, and broadcast monitoring. Universities and engineering colleges frequently use BNC connectors in laboratory setups for oscilloscopes and signal generators, making them familiar to electronics and communication engineering students. The connector comes in two impedance variants: 50-ohm for RF applications and 75-ohm for video signals. Despite the rise of HDMI and USB-C, BNC remains widely used in professional video broadcasting and legacy network equipment. Knowledge of BNC connectors may appear in JEE Advanced physics practicals, GATE electronics questions, and technical interviews for roles in networking or surveillance. Understanding its design and usage helps in grasping fundamental concepts of signal transmission and impedance matching.
