Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
177 words
A fiber optic splice assembly comprising: an elongated tubular splice sleeve having a longitudinal axis and a first end formed to receive and align an optical fiber, said first end including a first diametered bore extending a given distance inwardly of said sleeve and tapering to a narrower, second diametered bore, said first diametered bore being of a size to receive a coated fiber and said second diametered bore being of a size to receive a stripped fiber; a middle portion and a contiguous second end, each having a third diametered bore, larger than said first diametered bore, said middle portion containing a mated pair of elastomeric halves therein; said second end containing a fiber guide comprised of a cylindrical member having an outside diameter equal to the diameter of said third diametered bore, said fiber guide including a fourth diametered bore extending a given distance inwardly of said guide and tapering to a narrower, fifth diametered bore, said fourth diameter being equal to said first diameter and said fifth diameter being equal to said second diameter.
Claim 2
Dependent Claim
177 words
A fiber optic splice assembly comprising: an elongated tubular splice sleeve having a longitudinal axis and a first end formed to receive and align an optical fiber, said first end including a first diametered bore extending a given distance inwardly of said sleeve and tapering to a narrower, second diametered bore, said first diametered bore being of a size to receive a coated fiber and said second diametered bore being of a size to receive a stripped fiber; a middle portion and a contiguous second end, each having a third diametered bore, larger than said first diametered bore, said middle portion containing a mated pair of elastomeric halves therein; said second end containing a fiber guide comprised of a cylindrical member having an outside diameter equal to the diameter of said third diametered bore, said fiber guide including a fourth diametered bore extending a given distance inwardly of said guide and tapering to a narrower, fifth diametered bore, said fourth diameter being equal to said first diameter and said fifth diameter being equal to said second diameter.
Claim 3
Dependent Claim
52 words
The assembly of claim 1 wherein a first vent hole is provided in said first diametered bore, adjacent said second diametered bore and a second vent hole is provided in said third diametered bore between an end of said mated pair of elastomeric halves and the inner end of said fiber guide.
