An optical fiber cable connector includes a ferrule subassembly, in which a ferrule is mounted into a receptacle including a barrel section having a flange at its base. The ferrule subassembly is loaded into an enclosure having a plug housing at its lead end. The plug housing is configured to provide a connection between an endface of a multicore fiber mounted into the ferrule and a corresponding surface in a mating socket. A collar is rotatably mounted onto the barrel section of the ferrule subassembly such that it butts up against the flange. The collar has an opening that fits around the barrel section, and an outer perimeter that fits into a receiving cavity with the plug housing. The ferrule, receptacle, receptacle barrel section, mounted multicore fiber, enclosure, and plug housing have a common longitudinal axis. As a result, the ferrule, receptacle, receptacle barrel section, and mounted multicore fiber are continuously rotatable with respect to the enclosure and plug housing, thereby enabling a precise rotational alignment of the multicore fiber within the enclosure.

An optical fiber connector that is tunable despite being fully assembled has a assembly having an enlarged ferrule holding member or flange that has a multi-faceted periphery, preferably in the shape of a hexagon. The connector has a front housing portion that has a multi-faceted seating region for the flange. The flange is disengageable from the seating region for tuning rotation by being movable axially toward the rear of the housing against the force of a spring. The connector can be tuned by incremental rotations of the assembly when the flange is disengaged.

A tuning wrench for tuning optical fiber connectors has an enlarged portion from which extends a limiting portion having a diameter greater than the diameter of the opening in the ferrule housing portion of an optical connector. A tubular member protrudes from the limiting portion and has an internal diameter dimensioned to slide over the connector ferrule. The distal end of the tubular member has a pair of tangs adapted to fit within or openings in the front of the flange portion of the ferrule-barrel member of the connector. The distance from the face of the limiting member to the tangs is such that axial pressure on the wrench moves the flange rearwardly out of engagement with its housing but the face of the limiting member butts against the front of the housing before the spring member within the housing bottoms. Rotation of the wrench thus causes rotation of the ferrule-barrel assembly to alter the angular orientation of the eccentricity vector of the ferrule.

A tuning index tool for use in determining the degree of tuning necessary for a tunable optical fiber connector has a first stationary member having a connector adapter affixed thereto and a second movable member within the first member and spring loaded with respect thereto. The second member has a connector adapter affixed thereto axially aligned with the adapter in the first member. The movable member is incrementally rotatable with respect to the stationary member by being pulled against the spring force to disengage the ferrules of connectors in the adapters, which are aligned in a split sleeve. Rotation changes the orientation of the eccentricity vectors of the two connectors, and hence the insertion loss. Measurements of insertion loss are made, and the orientation of the connectors for minimum loss is noted. The number of incremental rotations of the tool indicates the incremental rotation of the ferrule of the connector under test, the eccentricity vector orientation of the other connector being known, that is necessary to achieve minimum insertion loss for the connector with connectors have a known eccentricity vector orientation.

A plug type connector is adapted to be latched to a backplane wall in a fixed position and has a tapered front, nose or connector end for insertion into an adapter which plugs into the backplane wall. The adapter may be misaligned in any or all of the X, Y, Z axes. The tapered nose cams the X or Y misaligned adapter into axial alignment as the adapter and its mount are being inserted. A shortened front or connector end of the connector causes the ferrule of the connector to project beyond the optical plane of the connection so that it reaches a ferrule in a Z aligned adapter to complete the connection. A coil spring within the housing of the connector is tuned to allow counter movement of the ferrule where the ferrule in the adapter is too long, thereby shifting the position of the optical plane. The connector has a ferrule-barrel assembly within a housing and an insert member which has an enlarged diameter portion which is contained by openings in the housing to prevent rotation of the ferrule-barrel assembly.

An optical fiber ferrule has a plurality of guide holes therein for guiding a respective plurality of flat-sided fibers at an end of a multifiber optical fiber cable. The fibers' flat sides identify a particular rotational orientation of the fiber. Rotational alignment is achieved by urging the fibers' flat sides against a corresponding reference surface within the ferrule or within an alignment fixture. Also described is a fiber array block having a plurality of V-shaped grooves extending across an outer surface and terminating at an endface. The V-shaped grooves are shaped to guide a respective plurality of flat-sided fibers. A lid is installable across the plurality of V-shaped grooves, over fibers that have been loaded therein.

A connector that enables fiber optic cables to terminate at equipment in cabinets having little space available for cable routing, without over bending. The construction includes a connector housing, and a yoke including a collar joined to a rear end of the housing. A tubular cable bend limiter is fixed at one end to the collar and the limiter directs a cable containing one or more bend insensitive fibers through a bend of, e.g., 90 degrees, between the collar and the opposite end of the limiter with a fiber bend radius of less than one inch (25.4 mm). If the limiter creates a fiber bend radius of 0.300 inch (7.62 mm), the distance between the front of the connector and the cable after bending may be as little as 1.26 inches (32 mm), allowing the cable and connector to be routed and terminated in limited space without impairing performance.
