Therefore, because the second sleeve 50 fits snugly within {HEAD ~ the terminal portion} of the prealigned bore 92, the longitudinal axis of {TAIL ~ the core} 20 is substantially aligned with the longitudinal axis of the bushing 94 thereby ensuring substantial alignment between juxtaposed waveguides
