Abstract:
1. An optical fiber termination assembly comprising: a housing having a first engagement element and a support adapted to support at least one optical fiber extending in a longitudinal direction; and at least one locking mechanism attached to the housing and arranged to be operable to apply a bias towards the support such that, when an end of a second optical fiber is fixedly supported by the support extending in the longitudinal direction and an engagement component of a first fixture is engaged with the first engagement element of the assembly, a first optical fiber of the first fixture extends longitudinally therefrom towards the support and the locking mechanism is operable to be biased against the first optical fiber to maintain an end of the first optical fiber at the support fixed in a first position and only in a predetermined alignment with the end of the second optical fiber, wherein, upon placement of the first optical fiber on the support when the locking mechanism is not biased against the first optical fiber, the end of the first optical fiber is at a predetermined orientation and a predetermined position at the support associated with the predetermined alignment by engagement of the first engagement element with the engagement component, wherein a portion of the support includes a first rigid portion and a first deformable portion for contacting the first optical fiber, and wherein the locking mechanism includes a second rigid portion and a second deformable portion for contacting the first optical fiber, the first and second rigid portions being independent of each other, and the first and second deformable portions being independent of each other, the locking mechanism having open and closed positions, the closed position being operable to press against the first optical fiber, such that when the locking mechanism is in the open position, each of the first and second deformable portions has a length and a second cross sectional area defined in directions transverse to the length along an inner section along the length, respectively, and a first cross sectional area defined in directions transverse to the length along outer sections along the rest of the length thereof, respectively, and each of the first and second rigid portions has a length and a first cross-sectional area defined in directions transverse to the length along an inner section along the length, respectively, and a second cross-sectional area defined in directions transverse to the length along outer sections along the rest of the length thereof, respectively, wherein the respective second cross sectional areas of the first and second deformable portions are less than the respective first cross sectional areas of the first and second deformable portions, and prior to contacting the first optical fiber each of the first and second deformable portions has a groove along the length for receiving the at least one optical fiber, and when the locking mechanism is in the closed position, the first and second rigid portions form an axial bore having (i) a bore length, (ii) an inner portion having a cross-sectional area along the bore length, and (iii) outer portions along the rest of the bore length thereof, each of the outer portions having a larger cross-sectional area than the inner portion of the axial bore, the inner portion of the axial bore providing a greater force against the end of the first optical fiber than the outer portions thereof such that an inner region defined by the first and second deformable portions is compressed to a smaller cross-sectional area along the respective lengths thereof than outer regions of the first and second deformable portions along the rest of the respective lengths thereof.
