摘要： A multi-channel optical connector that includes a multi channel optical fiber block including at least one optical fiber capable of being optically coupled to at least one optical device. The multi-channel optical fiber block is incorporated in a plastic molding that is complimentary in shape to that of an optical device array block, and thus can be plugged into the optical device array block. The close tolerances maintained in manufacturing of the connector results in accurate alignment of the fibers captured in the multi-channel optical fiber block with the optical devices in the optical device array block. The close tolerances can be achieved by using MEMS (Micro Electro Mechanical System) processing techniques to manufacture the V-grooves in a silicon V-block, which is part of the multi-channel optical fiber block. Alternatively, V-grooves can be produced in the multi-channel optical fiber block by plastic molding. The connector includes a housing that surrounds the connector core and the buffered fiber that is outside the cable jacket to providing protection and strain relief for the fibers.
