Flexible optical closure and other flexible optical assemblies
First Claim
1. A flexible closure being attached to at least one optical fiber cable deployable using cable installation methods:
- the flexible closure comprising at least one molded portion, the molded portion being formed of a resilient and flexible material thereby forming a durable and flexible body associated with and protecting optical components associated with the flexible closure, the optical components comprising at least one optical fiber in the fiber optic cable and at least one other optical component forming an optical connection with the at least one optical fiber; and
the flexible closure being resiliently bendable and twistable in variable directions, and being flexible in response to stresses acting on the flexible closure due to cable installation equipment and maintaining mechanical integrity of the flexible closure protecting the performance on the optical components thereinwherein the flexible closure has a bending force ratio from about 1.0 to about 5.0.

Abstract
Flexible closures and other flexible optical assemblies that are installed within a factory, or in the field, and then deployed using cable installation methods, wherein the flexible closures and assemblies have the ability to bend and twist without incurring physical damage to their structure, optical fibers and splices disposed within, and without significant attenuation in the optical fibers when exposed to conventional installation stresses. Flexible closures that replace conventional substantially rigid closures in order to facilitate pre-engineered and assembled distribution cable installation within an optical network, and the physical, bending and material properties of such closures, and methods of manufacturing and installing the same.

10. A flexible closure assembly for use in a fiber optic distribution cable assembly, comprising:
-
a distribution cable comprising a plurality of optical fibers and having at least one predetermined mid-span access location positioned along the length of the distribution cable; at least one optical fiber of the distribution cable being accessed and terminated from the distribution cable at the mid-span access location; a tether comprising a first end attached to the distribution cable at the mid-span access location and at least one optical connection being an optical fiber optically connected to the at least one terminated optical fiber of the distribution cable; and a flexible closure positioned about the mid-span access location, said flexible closure being resiliently bendable and flexible in response to stresses acting on the flexible closure due to cable installation equipment, without incurring substantial breakage or cracking of the molded portion of the optical connection, and without significant degradation of optical performance of the optical connection wherein the flexible closure is capable of bending to about the minimum bend radius of the distribution cable upon which it is Installed, and the flexible closure has a bending force ratio of about 1.0 to about 5.0. and has an aspect ratio of about 10 to about 30. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
