bayonet fibre optic connector (BFOC)
Connectors can be classified according to the way they are locked. There are various locking techniques of which the bayonet lock is a quick-release plug connection. The bayonet lock is available for coaxial cables and optical fibers.
With bayonet locking, the two connector parts are inserted into each other and the bayonet ring is rotated to the detent position.
For FO connectors, the bayonet lock is used with the ST connector and the mini- BNC connector. The ST connector, a widely used FO connector, is therefore also known as the Bayonet Fiber Optic Connector (BFOC). It is standardized by the International Electrotechnical Commission( IEC) under the IEC 608874-10 standard.
