Abstract

A housing for interconnecting an opto-electronic device with a ferrule includes a base, a cover cooperable with the base to define a chamber, and a mounting member is characterized by a pivot arrangement disposed on the mounting member and cooperating with at least one of the base or the cover for accommodating pivotal motion of the mounting member to permit the axis of the mounting member to translate in two orthogonal directions in a plane perpendicular to the axis of the chamber and also to permit the top of the mounting member to displace in the perpendicular plane to align the axis of the mounting member collinearly with the axis of the ferrule. The housing also includes an elastomeric board mount disposed in a sealing relationship between the base and the cover when the same are conjoined and arranged to seal legs on a substrate that extend through the elastomeric board mount.
