Abstract
An optical connector having a front and back orientation and suitable for operating with a temperature range, the connector comprising: (a) a ferrule comprising a first material having a first coefficient of thermal expansion (COE), and having no greater than a first diameter below a transition temperature with the temperature range, and no less than a second diameter above the transition temperature; (b) a spring disposed behind the ferrule and in contact with the ferrule to apply a forward urging force to the ferrule; and (c) a housing comprising a second material having a second COE, the housing defining a bore hole having a diameter greater than the second diameter, and an interface portion having a restricted bore hole having no greater than a third diameter below the transition temperature, and no less than a fourth diameter above the transition temperature.
