Abstract: A housing of a fiber optic connector such as an MT-RJ connector has a greater surface area and ridges for improved handling and grasping. A door is provided on a fiber optic connector socket to block light leakage from the socket. The door is compact and does not interfere with neighboring devices while closed. The connector has a housing that centers the ferrule and keeps it in a position for precise alignment with the opposing ferrule. A pin retainer is designed to allow insertion and removal of alignment pins in the field without the need for removing the connector from the fiber optic, so that male connectors can be connected to female connectors and vice-versa.

Abstract: A fiber optic connector in such as a male MT-RJ connector has a ferrule fixed to the housing. Ferrule-to-ferrule alignment is provided by the floating ferrule in the mating female MT-RJ connector. A field-installable connector includes a field termination unit with fiber stubs and index matching gel for receiving the cut ends of optical fibers. The fiber stubs extend into the ferrule of the connector. A loopback test unit includes a ferrule and housing like those of a standard connector. A fiber loop has both ends lodged in the fiber bores of the ferrule so that the loop will connect the transmitter of a transceiver to the receiver of the same transceiver when the unit is engaged in the connector of the transceiver. The fiber loop is held within a boot attached to the housing or ferrule so that the entire unit can be conveniently installed and removed, and so that numerous loopback testers can be used simultaneously even when the device under test has numerous closely-spaced transceivers.

Abstract: A fiberoptic feedthrough fastener and method for forming same comprising sliding a first and second sections of heat shrink tubing up a fiberoptic cable beyond a fastening point. The jacket of the cable is then stripped off at the fastening point, the strength member is stripped off slightly beyond the fastening point, and the exposed strength member is folded back away from the buffered fibers. A section of protective tubing is slid over the exposed buffered fibers until it abuts the end of the jacket. The second section of heat shrink tubing is slid down the cable and the protective tubing. The exposed strength member is caught by the second section of heat shrink tubing and pulled over and about the protective tubing. The second section of heat shrink tubing is then secured about the protective tubing and exposed strength member.

Abstract: A branching method for multi-fiber fiberoptic cables which comprises stripping off the jacket of a multi-fiber cable at the branching point, stripping the kevlar from the cable slightly beyond the branching point, folding back the kevlar over the jacket and holding the kevlar in place with heat shrink tubing leaving a portion of kevlar exposed about the end of the jacket with the individual buffered fibers extending beyond that point. Thereafter, a section of high grade heat resistant teflon tubing is slid onto each buffered fiber until a portion of the section of teflon tubing extends into the interior of said cable. Thereafter, a sheathing is prepared for each individual buffered fiber. The jacket of each sheathing is stripped slightly beyond its end point, the kevlar is folded back over the jacket and the kevlar is held in place with heat shrink tubing leaving a portion of kevlar exposed about the end of the jacket.
