METHOD AND APPARATUS FOR ALIGNING OPTICAL TRANSPORTS IN A FERRULE

摘要

Methods and apparatus for aligning optical transports, such as waveguides and optical fibers, in a ferrule of an optical connector. The ferrule has an open side through which optical transports may be inserted into a transport cavity in the ferrule from a direction transverse the longitudinal direction of the optical transports and ferrule. To assemble the optical transports in the ferrule, the ferrule is positioned with its front face abutting and aligned with a jig that has an opening substantially identical to the ferrule cavity. The jig has grooves in a bottom surface of the cavity into which the optical transports will be inserted for transversely aligning the optical transports. The optical transports are then dropped into the aligned cavities of the ferrule and jig through the open sides of the ferrule and jig so that the front ends of the optical transports sit at least partially in the V-shaped grooves of the jig, thereby aligning the transports in the transverse dimension. A press cures adhesive in the cavity to cure the adhesive and fix the transports in the ferrule. The optical transports are then cleaved or otherwise cut flush with the front face of the ferrule. The process is repeated for each row of optical transports with the height of the bottom of the cavity in the jig adjusted for each subsequent row by an amount equal to the thickness of a row of the optical transports.
