Abstract

Abstract An optical fiber duplex connector assembly wherein two individual optical fiber connectors are positioned and retained within a common housing, such that relative freedom of movement between the two connectors within the common housing facilitates positioning of the retained two connectors within a suitable receiving common housing (e.g., shroud). Such movement accomodates for manufacturing tolerances within the housing and/or connectors while still assuring successful insertion. A housing, having two chambers (one for each connector) and a cover assures the defined movable connector positioning while also providing effective retention. A boot may be attached to the housing to accomodate for severe bends and turns of the optical fiber cable, without loss of attenuation.

Claim 10
Dependent Claim 38 words
The optical fiber connector of claim 8 wherein said rib member includes a first width and said groove includes a second width, said second width of said groove being greater than said first width of said rib member.
Claim 11
Dependent Claim 29 words
The optical fiber connector of claim 1 further including a spring means positioned within said second housing for biasing said ferrule in a first direction within said second housing.
Claim 12
Dependent Claim 21 words
The optical fiber connector of claim 10 wherein said spring means comprises a compression spring concentrically positioned substantially about said ferrule.
Claim 13
Dependent Claim 21 words
The optical fiber connector of claim 1 wherein each of said second housings is movably positioned within said respective third housing.
Claim 14
Dependent Claim 67 words
