A multifiber connector is provided according to one embodiment which includes a multifiber ferrule, splice components and a crimp tube that defines a lengthwise extending passageway having a lateral cross-sectional shape that is generally oval for receiving and maintaining a plurality of optical fibers in a lateral side-by-side relationship. The crimp tube therefore provides the optical fibers to the splice components in an aligned and properly spaced manner for alignment and optical interconnection with respective optical fiber stubs. According to another embodiment, a fiber optic connector is provided that includes a ferrule, mechanical splice components, an associated cam member for actuating the mechanical splice components and means for controlling the position of the cam member relative to the mechanical splice components such that the cam member can be precisely moved from a first unactuated position to a second actuated position. As such, the fiber optic connector can be mechanically spliced to a plurality of optical fibers in a reliable manner so as to facilitate the field installation of a multifiber connector. the multifiber connector can also include a ferrule holder for aligning the ferrule and the splice components.

Disclosed is a connector assembly tool that performs three assembly functions on FC and ST type connectors having a factory installed fiber in response to moving a handle from a first to a second position, namely activating an optical fiber alignment device (a slider) to align an optical fiber of a given cable with a factory installed fiber in a connector and securing such alignment in place by crimping a crimp tube disposed about the cable sought to be connectorized while maintaining an abutment between the factory installed fiber of the connector and the optical fiber sought to be connected to the connector, such tool comprising a base, a car slideably disposed on the base moveable from a first to a second position, a handle pivotably mounted on the base slideably engageable with the car and moveable from a first to a second position, a stop device on the base engageable with the handle when the car is in the second position and a fiber holder affixed to the base and spaced apart from the car and stop device, the fiber holder adapted to maintain the above described abutting relationship.

Disclosed is a fiber optic mechanical splice having one or more grooves transverse to the groove in which the optical fibers lie to dissipate air trapped in index matching material from the junction point of the optical fibers.

Described is a fiber optic splicing enclosure to be installed within existing copper distribution pedestals. Elastic material holds the splicing enclosure in an essentially stationary position during limited movement of the ground surface due to frost heave or the like. Additional diagonally placed elastic straps secure the optical waveguides in a desired position.

An optical fiber connector includes a longitudinally extending ferrule having fusion access means defined therein such that an optical fiber stub and a second optical fiber can be fused in the field during installation of the optical fiber connector. In one embodiment, the fusion access means includes a fusion access slot which extends transversely across the ferrule from a first side of the ferrule to a bottom portion of the fusion access slot such that a bore defined longitudinally through the ferrule opens into the fusion access slot. In this embodiment, the radial distance between the bottom portion of the fusion access slot and the second side of the ferrule, opposite the first side, is greater than a predetermined radial distance such that the fusion access slot does not significantly weaken the ferrule so that the ferrule remains structurally intact during use. In another embodiment, the fusion access means includes a fusion access port defined transversely through the ferrule such that the fusion access port is in communication with the longitudinal bore and thereby defines an internal splice cavity in which the end portions of the optical fiber stub and the second optical fiber can also be fused to form an integral optical fiber. By carefully defining the fusion access means within the ferrule, however, the structural integrity of the ferrule can be maintained such that the resulting optical fiber connector is durable and strong.

摘要:
A ferrule boot for attachment to an optical fiber ribbon has a channel extending therethrough. The channel has at its distal end a first tapered lead-in section sized and dimensioned such that the optical fiber ribbon with the internal optical fibers stripped and exposed is insertable through the ferrule boot. The first tapered lead-in section is connected to a second tapered section, and the second tapered section prevents adhesives used to affix the optical fiber ribbon to a ferrule from wicking to the outside of the ferrule boot. The channel has a substantially straight section fitting intimately over the outside of the optical fiber ribbon to center and guide the exposed optical fibers to the center of the proximal end of the channel. In an embodiment, the ferrule boot also has a lip member disposed proximate to the proximal end of the channel to help seal the adhesive and ease insertion. Additionally, the lip may also prevent withdrawal of the optical fiber ribbon. In another embodiment, the ferrule boot also has a vent hole to allow air or other gases trapped in the ferrule boot cavity to vent to the ambient atmosphere.
