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.

Optical fibre connector

An optical sub assembly for receiving an optical fiber transmission line for coupling to an optical device, to a receptacle for use in such a sub assembly and to a method of manufacture of such a sub assembly. The optical sub assembly preferably provides electrical isolation between a receptacle having a nose for receiving the optical fiber and a package housing an optical device. The nose houses a ferrule containing a fiber stub which may be optically aligned with an optical device housed in a package before securing the receptacle to the package. The electrical insulation is provided between the nose and the package by a sleeve extending along a middle portion of the ferrule and an insulating portion positioned between the sleeve and the nose.

Optical sub assembly

The present invention relates to an optical fiber communication component (), and particularly a connector receptacle () for connecting to a connector plug () having an optical fiber () mounted within a projecting cylindrical ferrule. The connector receptacle () comprises a housing () that has a passageway () with an entrance for receiving the ferrule (). A split sleeve clamp () is seated within the passageway () and has an opening oriented towards the entrance for receiving the projecting ferrule (). A hollow sleeve () having a cylindrical outer surface () and an axially extending open channel (), is gripped by the split sleeve clamp to define the diameter of the opening to the clamp. The open channel () extends along the longitudinal axis () of the passageway () to allow optical radiation () to be transmitted through the channel () to/from said connector plug ().

Optical fiber connector

An optoelectronic component, such as an optical transceiver, contains one or more optoelectronic devices, such as a semiconductor laser or a photodiode. It also contains a metallic or metallized housing within which the optoelectronic devices are mounted, and an optical connector part to allow optical radiation to be coupled between the optoelectronic devices and fibres of a fibre optic communications network. The optical connector is disposed at least partly within an aperture in the housing. A metallic or metallized barrier is disposed between the one or more optoelectronic devices and the optical connector substantially to shield against transmission of electromagnetic radiation through the aperture (except of course for the transmission of optical radiation to be provided to, or received from the fibre optic communications network). This barrier can be provided as part of a metallized clip, adapted to fit around the optical interface between the optoelectronic devices and the outside of the transceiver. The optoelectronic devices may be separated into an optical assembly and an electrical assembly, each with a separate conductive shield, in which case the metallized barrier may provide a part of the conductive shield for the optical components on the optical assembly.
