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.

Field installable optical fiber connector and an associated method of

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.

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.

Optical fiber connector assembly tool

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.
