Abstract
An optical connector for operation within a temperature range, comprising: (a) a ferrule comprising a first material having a coefficient of thermal expansion COE-1, and a diameter no greater than a diameter d1 below a transition temperature Ts within the temperature range and no less than a diameter d2 above Ts; (b) a spring disposed behind and in contact with the ferrule to apply a forward force to the ferrule; and (c) a housing comprising a second material having a coefficient of thermal expansion COE-2 and defining a bore hole having a diameter greater than d2, and an interface having a restricted bore hole having a diameter no greater than a diameter d3 below Ts, and no less than a diameter d4 above Ts, wherein connector configuration is COE-2>COE-1 with d>d3 and d2<d4 or COE-2<COE-1 with d1<d3 and d2>d4.
