ABSTRACT:
The present invention relates to an optical fibre connector, and in particular to an optical port having a connector receptacle for receiving an optical fibre plug, and to an optical fibre connector assembly for transmitting and/or receiving an optical signal formed by an optical fibre connector and an optical fibre plug when these are joined together. The optical fibre connector assembly comprises an optical fibre connector and an optical fibre plug. The optical fibre plug includes a projecting ferrule and along an axis of this ferrule a first optical fibre. The optical connector including a hollow sleeve and within the sleeve a recessed ferrule and along an axis of this ferrule a second optical fibre. The sleeve has an open end for receiving and holding the projecting ferrule and has at the recessed ferrule a closed end, the arrangement being such that when the projecting ferrule is held within the sleeve both optical fibres are aligned to transmit and/or receive an optical signal along an optical axis defined by the fibres, and the closed end of the sleeve grips the recessed ferrule and the projecting ferrule more securely than the open end of the sleeve grips the projecting ferrule. The result is that if a force is applied at the open end of the ferrule to the projecting ferrule in a direction transverse to the optical axis then the first ferrule pivots within the sleeve about a point that lies closer to the closed end of the sleeve than to the open end of the sleeve.
