Abstract
Abstract An optical fiber assembly is described which comprises a housing (12) defining a passage (16) therethrough for residence of an optical fiber (14) therein and having a central axis (18) constituting an energy output axis, at least a portion of said passage adjacent said energy output axis extending along an axis in acute first angle (I) intersecting relation to said energy output axis and an elongate optical fiber (14) resident in said housing passage (16) and accordingly having disposition at said acute first angle (I) to said energy output axis in said passage portion, said fiber (14) defining an end face (22) juxtaposed with said energy output axis, said fiber end face (22) being at an acute second angle (II) to the fiber longitudinal axis (24). Lessened energy reflection characteristics are achieved by such an optical fiber assembly in optical connectors employing non-contacting fibers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
An optical fiber assembly, comprising: (a) a housing defining a passage therethrough for residence of an optical fiber therein and having a central axis constituting an energy output axis, at least a portion of said passage adjacent said energy output axis extending along an axis in acute first angle intersecting relation to said energy output axis; and (b) an elongate optical fiber resident in said housing passage and accordingly having disposition at said acute first angle to said energy output axis in said passage portion, said fiber defining an end face juxtaposed with said energy output axis, said fiber end face being at an acute second angle to the fiber longitudinal axis.
Claim 2
Dependent Claim
112 words
An optical fiber assembly, comprising: (a) a housing defining a passage therethrough for residence of an optical fiber therein and having a central axis constituting an energy output axis, at least a portion of said passage adjacent said energy output axis extending along an axis in acute first angle intersecting relation to said energy output axis; and (b) an elongate optical fiber resident in said housing passage and accordingly having disposition at said acute first angle to said energy output axis in said passage portion, said fiber defining an end face juxtaposed with said energy output axis, said fiber end face being at an acute second angle to the fiber longitudinal axis.
Claim 3
Dependent Claim
44 words
The invention claimed in claim 1 wherein said housing includes an end portion having exterior frustro-conical surface and wherein the entirety of said passage in said end portion extends along an axis in said acute first angle intersecting relation to said energy output axis.
Claim 4
Dependent Claim
