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, the ferrule also comprising an endface, and containing at least one fiber having a fiber end presented at the endface; (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; wherein the connector is configured in one of two ways, in a first configuration, the second COE is greater than the first COE, and in the second configuration, the second COE is less than the first COE; wherein, in the first configuration, the first diameter is greater than the third diameter and the second diameter is less than the fourth diameter; and wherein, in the second configuration, the first diameter is less than the third diameter, and the second diameter is greater than the fourth diameter.
