Abstract
Abstract An optical fiber unit assembly package consists of a protective body having a lid and defining a volume, an entry for an optical fiber cable penetrating the body, at least one optical fiber cable extending through the entry and defining a conduit for an optical fiber cable. An anchor for an optical fiber cable is disposed within the entry as is a clamp for an optical fiber extending through the conduit within the package in a manner to isolate an internal optical fiber unit assembly within the volume from tensile forces applied externally upon the fiber. Secure mounting for optical fiber units within the volume are also provided.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
An optical fiber unit assembly package comprising: a protective body having a lid and defining a volume, optical fiber cable entry means penetrating said body, at least one optical fiber cable extending through said entry means and defining a conduit for an optical fiber, means for anchoring said optical fiber cable within said entry means, means for clamping an optical fiber extending through said conduit at a point within the package beyond said means for anchoring in a manner to isolate an internal optical fiber unit assembly associated with said optical fiber within said volume from tensile forces applied externally upon said fiber; and means for securely mounting optical fiber units within said volume.
Claim 2
Dependent Claim
114 words
An optical fiber unit assembly package comprising: a protective body having a lid and defining a volume, optical fiber cable entry means penetrating said body, at least one optical fiber cable extending through said entry means and defining a conduit for an optical fiber, means for anchoring said optical fiber cable within said entry means, means for clamping an optical fiber extending through said conduit at a point within the package beyond said means for anchoring in a manner to isolate an internal optical fiber unit assembly associated with said optical fiber within said volume from tensile forces applied externally upon said fiber; and means for securely mounting optical fiber units within said volume.
Claim 3
Dependent Claim
24 words
The optical fiber unit assembly package of claim 1 wherein said entry means comprises a cylindrical ferrule disposed in a hole through said body.
Claim 4
Dependent Claim
43 words
The optical fiber unit assembly package of claim 2 wherein said means for anchoring comprises a circular spring clamp disposed about said ferrule in a manner to retain a cable strength member and an adhesive bond to strengthen and seal the anchoring penetration.
Claim 5
Dependent Claim
37 words
The optical fiber unit assembly package of claim 1 wherein said means for clamping the fibers comprises upper and lower clamp members defining surfaces upon which are mounted rubber slabs between which said optical fibers are compressed.
Claim 6
Dependent Claim
42 words
The optical fiber unit assembly package of claim 1 wherein said means for securely mounting the optical fiber units comprises a tight fitting polymer tube disposed about said fiber optic unit and subsequently compressed between said lid and body of said package.
Claim 7
Dependent Claim
50 words
The optical fiber unit assembly package of claim 1 further comprising means for sealing the package comprising a circumferential groove defined by said body into which there is disposed sealing material subsequently compressed by the lid in a manner to form a gasket between lid and body of said package.
Claim 8
Dependent Claim
25 words
The optical fiber unit assembly package of claim 1 further comprising means external of said package body for relief of strain upon said optical fiber.
