Multi-core optical fiber connector

A method for manufacturing a fiber array, the method comprising the steps of:

• providing a plurality of posts, each of the posts defining a longitudinal passage therethrough;
• extending first portions of optical fibers through the passages of the posts respectively;
• providing a plurality of ferrules, each of the ferrules defining an annular groove therein;
• extending second portions of the fibers into the ferrules respectively;
• providing a plurality of rings, and engaging the rings in the grooves of the ferrules respectively;
• placing a spring around each of the ferrules respectively, with one end of each of the springs abutting against a corresponding ring;
• providing a first plate defining a plurality of threaded through holes, and engaging the posts in the threaded through holes respectively;
• providing a second plate defining a plurality of through holes respectively retaining the ferrules therein, and securing the second plate to the first plate with bolts such that an opposite end of each of the springs abuts against the second plate;
• and
• providing a housing, and fixing the first plate, the second plate, the ferrules and the springs in the housing.

A fiber array comprising:

• a first plate defining therein a plurality of through holes arranged in a matrix manner;
• a plurality of ferrules snugly received in the corresponding through holes, respectively;
• a second plate having a plurality of posts in the matrix manner corresponding to said through holes, said posts being in threaded engagement with the second plate and adjustably moveable relative to the second plate in an axial direction perpendicular to said second plate, each of said posts adjustably moving the corresponding ferrule relative to the first plate in said axial direction;
• and
• a plurality of fibers extending through the corresponding posts and ferrules, respectively, wherein a distal end of each of said fibers is retainably disposed in the corresponding ferrule.

A fiber array comprising:

• a plurality of ferrules each comprising an outer surface, a first end and an opposite second end, and a longitudinal retaining hole defined therethrough for extension of a corresponding fiber thereinto;
• a plate having a plurality of first and second through holes therein;
• a plurality of posts threadedly engaging in the first through holes;
• and
• a plurality of springs exerting resilient force on the ferrules;
• wherein the ferrules are held in the second through holes of the plate and are adjustable relative to a main face of the plate.
