Patent number: 6635828Abstract: The composite electrical insulator comprises an integrated optical fiber sensor placed inside the insulator. The integrated sensor can be a fault sensor constituted by an optical fiber placed on the support rod of the insulator and having optical cladding that melts at a temperature which is critical for the insulator. The integrated sensor can be a sensor for measuring stresses of mechanical or thermal origin acting on the insulator while it is in operation. It is constituted by an optical fiber having a Bragg grating implanted therein. The Bragg grating is placed on the support rod of the insulator or on a metal end-fitting of the insulator.Type: GrantFiled: May 21, 2002Date of Patent: October 21, 2003Assignee: Sediver Societe Europeenne d'Isolateurs en Verre et CompositeInventors: Damien Lepley, Alain Mure-Ravaud, Alain Trouillet

Patent number: 6619994Abstract: A jack plug of digital connector includes a jack plug with an optical fiber cable. The device is characterized in that the jack plug is composed of a front plug and a tail plug. A plug hole is disposed at the back part of the front plug. The tail plug has an insertion hole and on the front part of the tail plug possesses two clips at upper and bottom side respectively. The optical fiber cable picks through the insertion hole of the tail plug and then insert the tail plug into the plug hole of the front plug so as to make the two clips of the tail plug hold the optical fiber cable and fixed them at the back end of the front plug.Type: GrantFiled: December 19, 2002Date of Patent: September 16, 2003Assignee: Jess-Link Products Co., Ltd.Inventors: Zen-Chyuan Chen, Kuo-Chiang Wu

Patent number: 6618526Abstract: A fiber optic cable having at least two interfaces being formed by first and second members. Between the interfaces is at least one retention area having an optical fiber component disposed therein. The retention area is disposed generally longitudinally and non-helically relative to an axis of the cable. The cable may also include a cable jacket substantially surrounding the members, a cushioning zone adjacent the optical fiber component, a water-blocking component and/or an interfacial layer. In another embodiment, a fiber optic cable includes a strength group having at least one strength member and an optical fiber being proof-tested to 125 KPSI or greater.Type: GrantFiled: September 27, 2001Date of Patent: September 9, 2003Assignee: Corning Cable Systems LLCInventors: William S. Jackman, Louis A. Barrett

Publication number: 20030147604Abstract: A grounding and transition assembly for providing combined electrical grounding and distributed transition of a bundle of fiber optic strands associated with a fiber optic cable. The assembly includes a three dimensional housing having an assembleable top and bottom and defining a first section proximate an inlet end for seating an inserting end of the fiber optic cable. The assembleable top and bottom further defining a second substantially open interior section communicable with the first section and extending to an open outlet end. A grounding cable has a first end secured to the three dimensional housing, a second end of the grounding cable securing to a remote location from said housing and providing for conducting of electrical charge associated with the fiber optic cable away from the housing. A three dimensional insert sealingly engages within the second interior section and includes a plurality of interiorly defined apertures.Type: ApplicationFiled: February 1, 2002Publication date: August 7, 2003Inventors: Alejandro L.
