Abstract
Abstract A polishing bushing 24 for polishing by hand an end face 26 of an optical fiber supported in an alignment ferrule 34 of an optical fiber connector 20. The polishing bushing 24 comprises a body portion having one or more openings 61 extending therethrough from a front surface 52 to a rear surface 53 thereof to permit visual monitoring of a polishing operation as it is being performed, and securing means 62 for securing an optical fiber connector 20 to the bushing 24 to permit the end face 26 of an optical fiber supported in an alignment ferrule 34 thereof to be polished. The bushing body portion 51 preferably comprises an annular outer ring portion 54 connected to a central hub portion 56 by a plurality of radially extending spoke portions 57 to provide a plurality of arcuate openings 61 between the spoke portions 57. The polishing bushing 24 of the invention is light in weight, comfortable to grip and use and permits a polishing operation to be carried out in an efficient, controlled manner.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
126 words
A polishing bushing for polishing an end face of an optical fiber supported in an optical fiber alignment ferrule, comprising: a body member having a front surface and a rear surface and a central bore extending therethrough in which an end of the alignment ferrule is to be disposed; and securing means for securing the ferrule to the body member for maintaining an end face of the ferrule and the end face of the optical fiber supported therein to be polished proximate the front surface of the body member, wherein said body member includes a plurality of spaced openings surrounding said bore, each of said openings extending therethrough from the front surface to the rear surface thereof to permit visual monitoring of a polishing operation therethrough.
Claim 2
Dependent Claim
126 words
A polishing bushing for polishing an end face of an optical fiber supported in an optical fiber alignment ferrule, comprising: a body member having a front surface and a rear surface and a central bore extending therethrough in which an end of the alignment ferrule is to be disposed; and securing means for securing the ferrule to the body member for maintaining an end face of the ferrule and the end face of the optical fiber supported therein to be polished proximate the front surface of the body member, wherein said body member includes a plurality of spaced openings surrounding said bore, each of said openings extending therethrough from the front surface to the rear surface thereof to permit visual monitoring of a polishing operation therethrough.
Claim 3
Dependent Claim
128 words
A polishing bushing for polishing an end face of an optical fiber supported in an optical fiber alignment ferrule, comprising: a body member having a flat front surface and a rear surface and including an outer ring portion, a central hub portion having an bore extending therethrough in which an end of the alignment ferrule is to be disposed, and a spoke portion connecting said ring portion and said hub portion and defining an opening therebetween to permit visual monitoring of a polishing operation therethrough; and securing means for securing the body member to the optical fiber alignment ferrule for maintaining an end face of the ferrule and the end face of the optical fiber supported therein to be polished proximate the front surface of the body member.
Claim 4
Dependent Claim
128 words
