Abstract
Polarization of the optical fibers (24, 32) of pin-and-socket-type optical fiber termini is provided by extending a sleeve (44) around an optical fiber terminus (15, 26), positioning the optical fiber terminus in a body (11, 12) with the sleeve (44) and body having means for positioning the sleeve (44) in predetermined rotational position, then rotating the optical fiber terminus (15, 26) until its fiber (24, 32) achieves a known polarization, and bonding the fiber and sleeve together by an adhesive (57). The terminus (15, 26) and sleeve (44) may be removed from the body (11, 12) and placed in an optical fiber connector (64, 67) by positioning the sleeve in a known rotational position relative to the connector, which will cause the optical fiber to have a predetermined polarization in the optical fiber connector.

The method of achieving predetermined polarization of an optical fiber comprising the steps of
- positioning a polarization preserving optical fiber in an optical fiber terminus,
- associating with said optical fiber terminus a member such that said terminus is rotatable relative to said member,
- forming an opening in a body,
- positioning said optical fiber terminus in said opening,
- locating said member in a predetermined rotational position relative to said body,
- then rotating said optical fiber terminus relative to said member and to said body to a rotational position in which said optical fiber has predetermined polarization, and
- then rotationally locking said member to said optical fiber terminus, whereby said optical fiber terminus and said member can be removed from said body and said optical fiber can be given a predetermined polarization by locating said member in a predetermined rotational position.
The method of achieving predetermined polarization of a polarization preserving optical fiber comprising the steps of
- positioning a polarization preserving optical fiber in an optical fiber terminus,
- extending around said optical fiber terminus a member which is rotatable relative to said terminus,
- forming an opening in a body,
- positioning said optical fiber terminus in said opening,
- forming cooperative abutment means cn said member and said body,
- locating said member relative to said body in a predetermined rotational position by said cooperative abutment means,
- rotating said optical fiber terminus relative to said member and to said body to a rotational position in which said optical fiber has predetermined polarization, and
- then bonding said member to said optical fiber terminus such that said optical fiber terminus and said member can be removed from said body and said optical fiber can be given said predetermined polarization upon similar association of said optical fiber terminus and said member with any such body.
The method of achieving predetermined polarization of a polarization preserving optical fiber comprising the steps of
- providing a first optical fiber connector section,
- positioning a first polarization preserving optical fiber in said first connector section such that said first optical fiber has a predetermined polarization,
- providing a second optical fiber connector section that includes a body having an opening therethrough, an optical fiber terminus in said opening and a second polarization preserving optical fiber in said optical fiber terminus and secured thereto,
- associating with said optical fiber terminus a member such that said terminus is rotatable relative to said member,
- locating said member in a predetermined rotational position relative to said body,
- connecting said first optical fiber connector section to said second optical fiber connector section so that the ends of said first and second optical fibers are in abutment,
- rotating said optical fiber terminus relative to said member and to said body to a rotational position in which said second optical fiber has predetermined polarization with respect to said first optical fiber, and
- then fixing said member on said optical fiber terminus such that said optical fiber terminus and said member can be removed from said body and said second optical fiber can be given a predetermined polarization by positioning said optical fiber terminus in an opening in a body and locating said member in predetermined position relative to said last mentioned body.
