Abstract
Abstract A termination for optical members comprises an alignment ferrule 1 and an optical fiber member 3 having a buffer 4 and an optical fiber 2. The alignment ferrule 10 has a tubular passagway 22 for encircling the buffer 4 and the optical fiber 2, and a tip 9 with centrally disposed aperture 13 therethrough for closely receiving an end of the fiber 2 from the tubular passsageway 22. The tubular passageway 22 of the alignment ferrule has a connection section with inwardly directed threads 32. The termination 7 further comprises a crimping body 8 of deformable, elastic material intimately surrounding the flexible buffer 4 and fiber 2. The crimping body 8 has a connection section 29 with outwardly directed threads 31 which engage with the inwardly directed threads 32 of the passageway 22 of ferrule 1.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
A termination for optical members comprising an alignment ferrule and an optical member having buffer and optical fiber wherein the alignment ferrule comprises an elongated sleeve body and has tubular passageway for encircling the buffer and optical fiber, and a tip with centrally disposed aperture therethrough for closely receiving an end of the fiber from the tubular passageway wherein; the tubular passageway of the alignment ferrule has a connection section with inwardly directed threads and further comprising a crimping body of deformable material intimately surrounding the flexible buffer and fiber, the crimping body having a connection section with outwardly directed threads engaged with the inwardly directed threads of the passageway.
Claim 2
Dependent Claim
110 words
A termination for optical members comprising an alignment ferrule and an optical member having buffer and optical fiber wherein the alignment ferrule comprises an elongated sleeve body and has tubular passageway for encircling the buffer and optical fiber, and a tip with centrally disposed aperture therethrough for closely receiving an end of the fiber from the tubular passageway wherein; the tubular passageway of the alignment ferrule has a connection section with inwardly directed threads and further comprising a crimping body of deformable material intimately surrounding the flexible buffer and fiber, the crimping body having a connection section with outwardly directed threads engaged with the inwardly directed threads of the passageway.
Claim 3
Dependent Claim
33 words
The termination of claim 1 comprising a crimping body having a tubular shaped portion and a rear connection portion with outwardly directed threads engaged with the outwardly directed threads of the crimping body.
Claim 4
Dependent Claim
44 words
The termination of claim 1 wherein the alignment ferrule is a bipartite body comprising the elongated sleeve body and the tip having profile through passage, the elongated sleeve body having inwardly directed threads and engaged with the outwardly directed threads of the crimping body.
Claim 5
Dependent Claim
32 words
The termination of claim 1 wherein; the tip having centrally disposed aperture is characterized by inwardly directed threads, engaged with the outwardly directed threads of the connection section of the crimping body.
Claim 6
Dependent Claim
61 words
The termination of claim 4 wherein the crimping body is characterized by a nose with connection section with outwardly directed threads positioned immediately adjacent to the nose so that the nose nests within the nose of the tip as the outwardly directed threads of the connection section are engaged with the inwardly directed threads of the connection section of the nose.
