Patent number: 6836609Abstract: A gas blocking device is used in an optical fiber repeater or other device to prevent the passage of gas, for example, to prevent nitrogen from escaping from a pressurized housing through a fiber holding tube or pigtail. The gas blocking device includes a fiber containing body, a fiber organizing insert, and a locking member securing the insert to one end of the body. The fiber containing body is attached to one end of the fiber holding tube. The fibers extend from the fiber holding tube through a passageway in the body, and each of the fibers extends through a fiber receiving hole in the fiber organizing insert. The insert engages the body such that the insert is prevented from rotating with respect to the body and the fibers are protected against microbending and other damage. A material, such as hot melt glue, fills at least a portion of the body and surrounds the fibers to block the gas from entering the fiber holding tube.Type: GrantFiled: January 25, 2001Date of Patent: December 28, 2004Assignee: Tyco Telecommunications (US) Inc.Inventors: William Girzone, Maurice Kordahi

Patent number: 6778743Abstract: A cable termination arrangement is used to terminate cables, such as armored fiber optic cables, to a connecting structure, such as a cable joint or coupling. Strength members, such as aramid rods, extending along the cable are terminated with radial termination members, such as crimping ferrules. The radial termination members extend into a termination cavity within the connecting structure and are spaced substantially equally, for example, using separators. An epoxy or other suitable retaining material encases the radial termination members, strength members, and separators.Type: GrantFiled: November 22, 2000Date of Patent: August 17, 2004Assignee: Tyco Telecommunications (US) Inc.Inventors: Maurice Kordahi, David Giordano, Tek-Che Chu, Tony S.

Patent number: 6763170Abstract: An apparatus for retaining and protecting spliced optical fibers. Optical fibers forming an extensive network, extending a great distance, are spliced together to provide the communication medium for the network. The apparatus includes a joint box for protecting the splices. Within the joint box is at least one arcuate-shaped splice retainer. The retainer secures the splices in a static position to prevent them from being damaged. Also, the retainer may include more than one arcuate layers for storing the splices. The arcuate layers organize the splices, so they are readily identifiable and accessible. In addition, the arcuate layers make efficient use of the limited space available for storing the splices. The joint box includes a center shelf longitudinally dividing the joint box into two compartments. To accommodate more splices, an arcuate retainer may be provided in each compartment by mounting an arcuate retainer on each side of the shelf.Type: GrantFiled: February 2, 2001Date of Patent: July 13, 2004Assignee: Tyco Telecommunications (US) Inc.Inventors: Maurice Kordahi, Steven Bernstein, Tat Chiu Lee, Tony S.

Patent number: 6728451Abstract: An optical fiber holding structure is used to restrain high fiber count fibers or to provide splice protection in a cable joint. Layers of fibers are inserted between a compliant splint member and a semi-rigid splint member, which are positioned within an outer gripping tube such as a heat shrink tube. Optionally, an internal support can be positioned between the layers of fibers. The assembly is heated causing the heat shrink tube to apply a gripping force to the splint members and fibers supported therebetween. Where more than two layers of fibers are being restrained, internal supports can be positioned between each of the fiber layers. One type of internal support includes a rigid beam coated with a compliant material.Type: GrantFiled: January 17, 2001Date of Patent: April 27, 2004Assignee: Tyco Telecommunications (US) Inc.Inventor: Maurice Kordahi

Patent number: 6584253Abstract: Sealed cable connections can be used to connect first and second cables to a sealed cable joint. The sealed cable connection at one end of the sealed cable joint includes a cable socket body positioned within an inner region of a housing. The cable socket body includes a passageway receiving one of the cables. A seal securing member is positioned within the inner region of the housing and secured into contact with the cable socket body. At least one seal, such as a resilient metal seal, is compressed between the cable socket body and the seal securing member to seal against the inner surface of the housing. The sealed cable connection can also include a cable seal positioned around the cable and within the passageway of the cable socket body.Type: GrantFiled: February 2, 2001Date of Patent: June 24, 2003Assignee: Tyco Telecommunications (US) Inc.Inventors: Maurice Kordahi, David Giordano, Robert Stix

Patent number: 6571042Abstract: A multi-body modular repeater system is capable of accommodating an increased number of fibers in an undersea fiber optic system. The system includes at least two repeater bodies connected in tandem with fiber optic cables coupled to the ends of the series of repeater bodies. A first plurality of optical fibers is amplified in one of the repeater bodies and a second plurality of fibers is amplified in the other repeater body connected in tandem. When the number of fibers in the fiber optic cable system is further increased, another repeater body may be added to accommodate the circuitry needed to amplify the additional fibers. In one embodiment, the repeater body housings are coupled together using an articulating joint that allows angular deflection of the repeater body housings while substantially preventing circumferential rotation of the repeater body housings with respect to one another. The articulating joint preferably allows angular deflection about at least two axes.Type: GrantFiled: September 26, 2000Date of Patent: May 27, 2003Assignee: Tyco Telecommunications (US) Inc.Inventor: Maurice Kordahi
