Patent Issued for Fiber Optic Cables and Assemblies and the Performance

Posted on 30th May 2013 @ 11:44 AM

The patent's assignee for patent number 8447154 is Corning Cable Systems LLC (Hickory, NC).

News editors obtained the following quote from the background information supplied by the inventors: "Along with the increase in the deployment of 'Fiber-to-the-Premises' (FTTP) optical networks, a need has arisen for increasing the performance, manageability, handleability and flexibility of fiber optic cables, cable assemblies and network components. With respect to outdoor installation environments, cables, cable assemblies and other network components are being developed that are more easily interconnected and installed within their environment, such as aerial installations and small diameter conduit. With respect to indoor environments and multi-dwelling units, cables and other network components are being developed to improve installation aesthetics and to interconnect an increasing number of subscribers. Within both environments, it would be desirable to develop components that perform better, are more flexible, robust and long lasting.

"Conventional cables, cable assemblies, jumpers, and other network components typically define structure that accommodates, and is in part, limited by the physical characteristics of the optical fibers contained therein. In other words, it is often the case that the physical and performance limitations of the optical fibers partly define assembly structure and processes associated with manufacturing the assemblies. Thus, optical fibers are one limiting factor in the evolution of fiber optic networks."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "In accordance with the purposes of the invention as embodied and broadly described herein, the present embodiments are addressed to fiber optic cables, jumpers and other assemblies including bend performance optical fibers in at least a portion thereof. The bend performance optical fibers have physical and performance characteristics that allow for reduced component size, tighter bend radius tolerances without degraded performance, which relaxes fiber routing and handling requirements.

"In one embodiment, the bend performance optical fibers are microstructured optical fibers comprising a core region and a cladding region surrounding the core region, the cladding region comprising an annular hole-containing region comprised of non-periodically disposed holes or voids, such that the optical fiber is capable of single mode transmission at one or more wavelengths in one or more operating wavelength ranges. The non-periodically disposed holes are randomly or non-periodically distributed across a portion of the fiber. The holes may be stretched (elongated) along the length (i.e. in a direction generally parallel to the longitudinal axis) of the optical fiber, but may not extend the entire length of the entire fiber for typical lengths of transmission fiber.

"In other embodiments, the bend performance fibers of the present embodiments may comprise at least a portion of fiber optic cables, fiber optic cable assemblies, network connection terminals, fiber optic hardware or any other fiber optic network component including at least one optical fiber maintained therein, routed therein or routed therethrough.

"It is to be understood that both the foregoing general description and the following detailed description present exemplary embodiments of the invention, and are intended to provide an overview or framework for understanding the nature and character of the invention as it is claimed. The accompanying drawings are included to provide a further understanding of the invention, and are incorporated into and constitute a part of this specification. The drawings illustrate various embodiments of the invention, and together with the detailed description, serve to explain the principles and operations thereof."
