Abstract
Abstract An optical fiber splice wherein a hollow cylindrical glass member is provided defining a longitudinal cylindrical aperture therein. Means adjacent the aperture defining a longitudinal groove parallel to the longitudinal aperture and in communicating relationship therewith is formed therein. A pair of tapered apertures are formed at each end of the glass member extending inwardly from the end surfaces and merging with the longitudinal cylindrical aperture and the longitudinal groove.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
106 words
An optical fiber splice comprising: a hollow glass cylinder having first and second end surfaces and defining a longitudinal cylindrical aperture therein, means adjacent said aperture defining a longitudinal groove parallel to said longitudinal aperture and in communicating relationship therewith, a portion of said hollow cylinder adjacent said first end surface defining a tapered aperture extending inwardly from said first end surface and merging with said longitudinal cylindrical aperture and said longitudinal groove, and a portion of said hollow cylinder adjacent its second end surface defining a tapered aperture extending inwardly from said second end surface and merging with said longitudinal bore and said longitudinal groove.
Claim 2
Dependent Claim
106 words
An optical fiber splice comprising: a hollow glass cylinder having first and second end surfaces and defining a longitudinal cylindrical aperture therein, means adjacent said aperture defining a longitudinal groove parallel to said longitudinal aperture and in communicating relationship therewith, a portion of said hollow cylinder adjacent said first end surface defining a tapered aperture extending inwardly from said first end surface and merging with said longitudinal cylindrical aperture and said longitudinal groove, and a portion of said hollow cylinder adjacent its second end surface defining a tapered aperture extending inwardly from said second end surface and merging with said longitudinal bore and said longitudinal groove.
Claim 3
Dependent Claim
31 words
The optical fiber splice of claim 1 wherein the diameter of said longitudinal aperture is between about 0.1 and 3 microns larger than the diameter of the fibers to be spliced.
