Patent number 8718425 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "The disclosure relates generally to fiber optic cable assemblies and more particularly to bend radius control of fiber optic cable assemblies within a pulling grip, including associated apparatuses and methods.
"So called pre-connectorized trunk assemblies require protection for the connectors and legs while in packaging and while being pulled through cable conduits or ducts, or over sheaves. Cable legs require some means to secure them while in packaging or in pulling grips to ensure the legs do not get bent to a radius smaller than a recommended minimum bending radius. The length of pulling grips can be minimized by folding legs over in some controlled fashion.
"Connectors in pulling grips are currently bundled together or the legs are made to different lengths, with a slightly staggered formation. By staggering the connector placement, the diameter of pulling grips can be made smaller enabling trunks to be pulled in smaller ducts or enabling the use of more trunks per duct. What is needed is a fiber optic assembly with a pulling grip that minimizes pulling grip length and diameter while protecting the cable legs and connectors inside.
"No admission is made that any reference cited herein constitutes prior art. Applicant expressly reserves the right to challenge the accuracy and pertinency of any cited documents."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "One embodiment of the disclosure relates to a cable assembly, for example, a trunk assembly, the assembly comprising at least one fiber optic trunk cable, the at least one fiber optic trunk cable including a jacket and at least one optical fiber extending beyond the jacket; at least one cable leg having a first length, the at least one cable leg being associated with the fiber optic trunk cable and containing the at least one optical fiber; at least one connector assembly, the at least one connector assembly in communication with the at least one optical fiber and being operatively connected to an end the at least one cable leg; and at least one pliable core having a second length, the at least one pliable core associated with the at least one cable leg, the cable leg being wrapped at least one time around the at least one pliable core, the second length being shorter than the first length.
"An additional embodiment of the disclosure relates to a method of making a cable assembly, the method comprising the steps of: providing a furcated optical cable assembly, the furcated optical cable assembly including at least one trunk cable, at least one furcation point and at least one cable leg having at least one optical connector on an end; providing a coupler; providing a convoluted sleeve; providing an expandable mesh; providing a pulling sock; providing at least one pliable core; wrapping the at least one cable leg around the at least one pliable core, causing the at least one optical connector to be a distance from the furcation point; installing the coupler about the furcation point; inserting the wrapped pliable core into the convoluted sleeve; mating the convoluted sleeve to the coupler; sliding the expandable mesh over the convoluted sleeve; securing the expandable mesh to the coupler and the convoluted sleeve; and installing the pulling sock about the coupler, the sleeve, the expandable mesh, and the wrapped pliable core to make the cable assembly.
"Additional features and advantages will be set forth in the detailed description which follows, and in part will be readily apparent to those skilled in the art from the description or recognized by practicing the embodiments as described in the written description and claims hereof, as well as the appended drawings.
"It is to be understood that both the foregoing general description and the following detailed description are merely exemplary, and are intended to provide an overview or framework to understand the nature and character of the claims.
"The accompanying drawings are included to provide a further understanding, and are incorporated in and constitute a part of this specification. The drawings illustrate one or more embodiment(s), and together with the description serve to explain principles and operation of the various embodiments."
