ABSTRACT:
A method for manufacturing a fiber optic terminus (10) having an optical fiber (12) disposed within and supported by a ferrule assembly (22). The method includes the steps of: stripping a fiber optic cable (8) to expose the optical fiber (12), bonding the stripped-end of the fiber optic cable (8) to a ferrule assembly (22), cleaving the optical fiber (12) in close proximity to a face surface (28) of the ferrule assembly (22), polishing the cleaved-end of the optical fiber (12) to achieve a terminus end profile, and inspecting the polished-end of the optical fiber (12) to determine whether the terminus end profile conforms to predefined acceptance criteria. The bonding operation is characterized by: applying a bonding adhesive (40) in a first region (A) between an aft body (26) of the ferrule assembly (22) and a strengthening member (18) of the fiber optic cable (8), applying a bonding adhesive (42) in a second region (B) between the optical fiber (12) and the ferrule assembly (22), elevating the temperature of the bonding adhesive (40), in a first operation, to solidify the bonding adhesive (40) in the first region (A), and elevating the temperature of the bonding adhesive (42), in a second operation, to cure the bonding adhesive (42) in the second region (B).
