Abstract: In a connector, an optical fibre cable is passed through a sub-assembly comprising a crimp body and collet. Then a sub-assembly comprising a threaded shell and ferrule is screwed onto the collet so that its tines are compressed in the ferrule onto the buffer coating of the cable at a location behind an end portion from which the buffer coating has been removed. Thus, the optical fibre passes through a precision hole for its projecting end to be removed by a cleaving blade passed across a slot. Two connectors are fixed to opposite ends of a rigid coupler by coupling nuts to bring opposed fibres into register.
