A temperature-compliant tube for fiber optic components is inserted into the exit port of an hermetically sealed package and extends into the interior of the package. An optical fiber extends through the temperature-compliant tube and is attached to a substrate interior of the package for coupling to an optical component mounted on the substrate. The optical fiber is hermetically sealed to the interior end of the temperature-compliant tube. The thermal coefficients of expansion and lengths for the temperature-compliant tube, the optical fiber between the substrate and the interior end of the tube, and the package body between the substrate and the exterior end of the exit port are tailored to provide zero differential expansion to enable the fiber optic components to be cycled over a wide temperature range without misalignment of the fiber relative to the optical component or mechanical failure of the fiber.

An optical connector in accordance with the invention includes a body to which an optical fiber supporting ferrule is mounted. A photo diode is rigidly mounted to the connector such that the photo active portion of the photo diode is optically coupled to the optical fiber. An interface is provided between the photo diode and an electronic circuit. In one form of the invention, the electronic circuit is mounted to the optical connector to facilitate this interface. Alternately, the circuit may be remote from the connector. In this case, the connector includes at least one electrically conductive wire lead for connecting the photo diode to the electronic circuit. An apertured substrate may be used to mount the photo diode to the ferrule with the photo diode optically coupled to the optical fiber through the aperture. The structure may be capped for protection against the environment, or alternatively, the circuit board itself may provide protection to the opto-electronic interface.

An electro-optical transducer module comprises a base member having a generally flat surface and a platform upstanding from the flat surface, an electro-optical transducer mounted on the platform, a fiber mount plate secured to the base member with one main face in confronting relationship with the generally flat surface of the base member, and an optical fiber secured to the fiber mount plate by way of its other main face. The optical fiber has an end face that is in optically-coupled relationship with the electro-optical transducer.
