Publication number: 20090324179Abstract: A system and method for automatically inserting optical-fiber (fiber-optics) cable jumpers into a patch panel to connect optical signal source equipment to optical signal destination equipment, and for automatically removing those jumpers from that patch panel to disconnect that equipment. This is accomplished robotically under computer control. Large scale fiber-optical splicings can be made, on the order of ten thousand (10,000) separate optical splices or more. Previous embodiments required hand insertion of these jumpers. Embodiments of the present invention permit any un-occupied port to be connected to any other un-occupied port, regardless of their input or output port status, where previous embodiments required only unoccupied input ports to be connected to unoccupied output ports.Type: ApplicationFiled: June 30, 2008Publication date: December 31, 2009Applicant: Verizon Corporate Services Group Inc.Inventors: Tiejun J.

Patent number: 7474829Abstract: Assemblies and methods for installing and maintaining aerial fiber optic cable are provided. Embodiments include a cable long enough to extend from two elevated support points and to provide enough slack for at least a portion of the cable to extend along the ground. The cable includes a wrapped portion for storing the slack and to elevate the entire cable above the ground. The wrapped portion being releasable in response to a force acting on the cable, such as a falling tree, allowing for at least a portion of the cable to fall to the ground and minimize the likelihood of the tree snapping the cable. Fasteners and frame members may be employed to support the wrapped portion. An embodiment may also include a cut-off apparatus for cutting the cable in response to the cable being pulled further once any slack in the cable has been expended.Type: GrantFiled: March 22, 2007Date of Patent: January 6, 2009Assignees: Verizon Services Organization, Inc., Verizon New England, Inc.Inventors: Tiejun J.
