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.
