Spelling: BNCConnector
A BNC-Connector [1] is a coaxial cable [2] connector. While there are
a handful of different BNC [3] flavours, they all provide the same
high quality connection. Because of the high quality of BNC-Connectors
[4], they are extremely common in commercial use (Telecommunications,
Video broadcasting, etc), and on medical and test equipment, where
performance is critical.
"BNC" stands for "Bayonet Neill Concelman", and is named after
engineer Carl Concelman who invented the connector in the late 1940's.
BNC-Connectors [5] mate using a 2-stud bayonet coupler, requiring only
a quarter-turn of the connector.
Many people may know the 50 Ohm version of BNC-Connectors [6] from an
old Ethernet [7] standard called 10base2 [8]. Other people may know
the 75 Ohm version from high-end DVD or older VHS players.
BNC-Connectors [9] these days are often rated to a maximum frequency
anywhere between 1 GHz and 10 GHz.
In Wireless LANs [10], Reverse-Polarity BNC Connectors [11] are more
common, and Reverse-Thread [12] versions also exist, although are
extremely rare. An alternative to the BNCConnector [13] is the
TNC-Connector [14].
