Abstract: A fiber optic cable connector device capable of coupling fiber optic cables for use in installing a fiber optic cable network including a cap member having an for receiving and securing a fiber optic cable end portion, a sleeve member having a retaining device to receive, engage and secure the cap member containing a fiber optic cable end portion, and a coupling member having a retaining device to receive, engage and secure the assembled fiber optic cable end portion, sleeve and cap members. An adapter, having fiber conduit slidably mounted within a support member housing, provides an interface for coupling multiple single-fiber carrying fiber optic cables and dual fiber carrying fiber optic cables. A method of terminating fiber optic ends with little or no polishing permits viewing of the illuminated fiber end-face through a microscope while adjusting the position in a the ferrule.

Abstract: Providing a simplified universal connector body. The new design providing significant more protection for the precision tip, and fiber optic cable than the previous design by completely enclosing all parts in a housing closed by a door, which can be removed for inspection. The sturdy crimp approach is retained allowing the design to survive significant abuse. Providing an improved ST outer housing. The new design eliminates the intricated jaw-hold-out in favor of a normally closed jaw that opens upon insertion onto the ST coupling. The jaw clamps is replaced by a jaw release. The new design is simpler and significantly more durable. Providing a new outer housing which enable the universal connector body to mate with the JR-type connector. This new design allows a one for one replacement of RJ-type copper connections with fiber optic connections on patch panels and electronic equipment.

Abstract: A new and improved apparatus and method for use in installing fiber optic cable, one embodiment of which utilizes a novel connector-coupling nut assembly, is disclosed herein. The apparatus largely comprises an elongated connector body with spring means disposed about the body's circumference for receiving and retaining a coupling nut which has a threaded internal configuration for mating with the spring means of the elongated connector body. When received by the connector body, the novel coupling nut is held in a securely captive position along the elongated connector body by suitable retaining means configured about the exterior surface of the connector body and the interior surface of the coupling nut, which means interact with each other.

Abstract: A method and device for organizing a bight of an optical fiber and the like at a splice or slack point is provided. The method comprises wrapping the bight about a cylindrical core to form a helix or a pair of helices of opposite handedness, thereby both minimizing the diameter of a container necessary to enclose that bight and maximizing the bend radius of the fiber. The bight may be laid on a sheet for convenient wrapping, and a plurality of fibers per sheet, sheets per core, or cores per splice may be used if the number of fibers to be organized is large. A ready means of encapsulation is also provided.

Abstract: A method and device for organizing the bight of an optical fiber and the like at a splice or slack point is provided. The method comprises laying the bight on a sheet in such a fashion that, when the sheet is wrapped about itself (and, generally, about a cylindrical core) in a spiral fashion, the radius of any bend in the fiber is greater than the minimum bending radius; and wrapping the sheet about itself (and the core). The method is suitable for both in-line and butt splices between fiber optic cables, and a ready means of encapsulation is also provided.

Abstract: A heat-recoverable closure assembly for enclosing e.g. cable splices comprising a heat-recoverable outer sleeve surrounding a body to be enclosed thereby, a support member surrounding the body and within the sleeve which support member has slotted end portions arranged to be capable of forming a tapering transition from the support member to the body, and a flexible barrier layer bridging the slots of the slotted portions. The barrier may act to seal the slots against ingress of moisture ior heat, and the barrier layer preferably covers substantially all of one surface of the support. Foamed polymer layers are particularly suitable as heat barriers, and metallic layers carried on a flexible carrier are particularly suitable as moisture barriers. The barrier may be inside or outside the support member, to suit end use requirements. A heat barrier will normally be placed outside the support member when the latter is made of thermoplastic material.
