Abstract
A connector for interconnecting the ends of two optical fiber cables to provide accurate alignment of the optical fibers free of stress from the mechanical linkage of the respective cables. The sheath at the adjoining end of each cable is split in two and separated to expose the optical fiber. The split ends of the sheath are inserted in separate diverging holes in a mounting ferrule while the exposed optical fiber is inserted in a central bore between the diverging holes. The sheath ends are anchored by cementing the ends in the holes. Only the very outer end of the exposed optical fiber is anchored by cement in the ferrule to fix the alignment of the fiber. The rest of the exposed fiber between the anchored outer end and the point at which the sheath is split is bowed slightly to relieve any tension on the fiber. The ends of the cables are joined by mounting the ferrules in a common connector body with the outer ends of the fibers held in abutting axial alignment.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
