摘要:
A fiber optic cable has one or more optical fibers, an inner tube surrounding the optical fibers, a strength member, an inner jacket surrounding the inner tube and strength member, and an outer jacket surrounding the inner jacket without being adhered to the inner jacket such that the outer jacket is easily strippable from the inner jacket. The inner jacket is constructed of a flexible, flame resistant material such as braided glass fibers, while the outer jacket may be constructed of a stiffer, flame retardant material such as polyvinyl chloride.

The present invention pertains to a multi-fiber optic connector system. The system contains a first housing and a second housing. The first housing contains (i) a first portion having at least one first cavity (ii) a second portion having at least one second cavity, a reference surface, and a first groove, and (iii) at least one alignment element disposed on the first groove. When an optical connector is slidably engaged into the first housing, the alignment element, having spring-like properties, contacts the optical connector and forces it against the reference surface.

摘要:
A portable, self-contained spray device and method for reaching and cleaning at least one optical surface having limited access. The spray device includes a fluid reservoir and a cover tube having an inner wall, an outer wall, a first end and a second end. A nozzle assembly at the first end of the cover tube includes a seal to provide substantially fluid-tight contact between the spray device and an optical surface. A delivery tube is located inside the inner wall of the cover tube, coaxial with the cover tube. The delivery tube coupled to the fluid reservoir directs fluid towards the nozzle assembly. An absorbent mounted adjacent to the outer wall of at least a portion of the cover tube collects liquid residues after application of fluid to an optical surface. The absorbent may be included in an absorbent cartridge that includes a detachable jacket surrounding the absorbent.

The present invention relates to a fiber optic cable assembly including a connector subassembly having a fiber optic cable terminated in a connector, the fiber optic cable having a minimum bend radius; and a strain relief boot attached to the connector subassembly, the strain relief boot having a core portion, a flexible extension with a proximal end and a distal end, the proximal end extending from the core portion. The flexible extension retains at least a portion of the fiber optic cable.
摘要:
An electrical connector assembly for terminating first and second electrical wires, the electrical connector assembly comprising a housing including a compartment for receiving first and second IDC elements and a cap movably mounted to the housing to cover the compartment. The cap is movable between an open position and a closed position. The cap includes a general body portion, a wire retention portion, and a latching mechanism. The wire retention portion includes first and second wire holders to retain and align the respective electrical wires within the housing for engagement with a gripping portion of the respective IDC element when the cap is placed in a closed position. The gripping force of the wire holders is less than a gripping force of the IDC elements. The latching mechanism can releasably fasten the cap to the housing when the cap is placed in a closed position. When the cap is returned to an open position after the cap was placed in the closed position, the first and second wires are retained by the first and second IDC elements and the first and second wire holders disengage the first and second wires from the cap.
摘要:
An anchored fiber optic cable and housing assembly. The assembly comprises: a fiber optic cable comprising a strength member and a jacket around the strength member, an anchor mounted on the cable, wherein the strength member includes a first end extending from the end of the cable and structurally engaged with the anchor; and a housing comprising an anchor cavity and a cable inlet, the anchor cavity comprising a shoulder for engaging with the anchor, wherein the anchor is mounted in the housing cavity and the cable extends through the cable inlet, and wherein the anchor cavity shoulder is engaged with the anchor to prevent the anchor from exiting the housing through the cable inlet. An anchored cable is also described, as are methods for mounting the anchor on the cable and mounting the cable in a housing. The cable may include a plurality of optical fibers in the jacket.
摘要:
A sonde for tracing an underground conduit has a separable casing which receives a removable inner shell, the transmitter electronics being located in the shell. The electronics may be permanently potted in the inner shell or removable therefrom. The interchangeability of the transmitter facilitates the use of different types of transmission signals without requiring the more expensive casing for each such transmitter. The shell also advantageously supports the battery, and further is free to rotate within the housing such that, as the cap is screwed onto the housing, the shell and battery are free to rotate, precluding damage to the battery leads which may be caused by twisting of the leads.
摘要:
A fiber identifer for detecting the presence or absence of an active data signal or a test signal in an optical fiber. The instrument includes a piston which positions a portion of the fiber under test against an optical detector, the piston being located within a housing, and the housing being attached to a drive rod. The rod is responsive to a levered actuation mechanism, but a damper controls the movement rate of the rod, and hence the piston, to slowly bend the fiber, minimizing disruption of any signal flowing through the fiber and preventing undue mechanical stress which could damage the fiber. A precision spring within the housing is used to limit the pressure applied by the piston against the optical fiber. The housing also includes a novel arrangement of electrical contacts to sense the position of the piston and, indirectly, the position of the rod.
