Patent number: 8270798Abstract: A cable routing guide attached to a fiber optic apparatus, such as a module positioned on a fiber optic equipment tray is disclosed. The cable routing guide is adapted to receive a length of at least one fiber optic cable intended to be connected to a cable connection point, such as a fiber optic adapter disposed on the module. The cable routing guide allows the at least one fiber optic cable to move in response to the fiber optic equipment tray or the module moving between a first position and a second position in a manner such that the length of the at least one fiber optic cable from the cable routing guide to the fiber optic adapter remains substantially unchanged. Moreover, the at least one fiber optic cable that is received by the cable routing guide may be retained and maintained by the cable routing guide without being tensed or stressed.Type: GrantFiled: March 1, 2010Date of Patent: September 18, 2012Assignee: Corning Cable Systems LLCInventors: Mark R. Dagley, David L. Dean, Jr., Daniel S. McGranahan, Brian K. Rhoney, Kevin L. Strause

Patent number: 7936962Abstract: An optical fiber distribution enclosure includes a housing defining an interior, a first fiber distribution area disposed within an upper portion of the interior, a second fiber distribution area disposed within a lower portion of the interior and a signal splitting area disposed between the fiber distribution areas. A splitter module secured within the signal splitting area has a connectorized splitter input optical fiber and connectorized splitter output optical fibers. A fiber parking area is movably disposed within the lower portion adjacent the second fiber distribution area for temporarily storing splitter output optical fibers that are not routed to the fiber distribution areas. An input fiber distribution area disposed within the interior interconnects an optical fiber of a feeder cable with the splitter input optical fiber. The splitter output optical fibers are eventually routed to a fiber distribution area and interconnected with a corresponding optical fiber of a distribution cable.Type: GrantFiled: April 12, 2010Date of Patent: May 3, 2011Assignee: Corning Cable Systems LLCInventors: Ronald L.

Publication number: 20100129030Abstract: Optical splitter modules and related mounting brackets, assemblies, and methods for mounting optical splitter modules in fiber optic equipment housings are disclosed. In certain embodiments, the optical splitter modules can be configured to be “universal,” if desired, meaning they are configured to employ certain common or similar dimensions or form factors. In this manner, the optical splitter modules can be installed in different types of fiber optic equipment housings that would otherwise support different form factors. The optical splitter modules are configured to be disposed and supported in different types of fiber optic equipment housings by being configured to be received in a mounting bracket. The mounting bracket is designed to support the form factor of the universal optical splitter module, but also configured to be compatibly installed in a particular type of fiber optic equipment housing in which the optical splitter module is desired to be installed.Type: ApplicationFiled: November 24, 2009Publication date: May 27, 2010Inventors: William J.
