Optical subassembly enclosure
First Claim
1. A sealing feature for a multiple-piece housing for optoelectronic devices, said sealing feature including a corrugated channel extending along a length of said housing to provide a seal between said housing pieces, said channel having a cross-sectional area that varies along the longitudinal direction of said channel and said channel capable of receiving therein a gasket having a substantially consistant cross-sectional, and said channel including wide sections and narrow sections extending along longitudinal direction of said channel wherein each wide section and narrow section includes a top width portion and a depth portion having dimensions, and the dimensions of the width and depth portions for each section provide a cross sectional area for that section, the cross-sectional area of each wide section being greater then the cross-sectional area of each narrow section.

Abstract
A sealing feature for a multiple-piece housing for optoelectronic devices. The housing provides EMI shielding and axial stain suppression for optical fibers coupled to optoelectronic devices retained within the housing. In an exemplary embodiment, the scaling feature includes a corrugated channel having a cross-sectional area that varies along the longitudinal direction of said channel and the channel retains a gasket having a substantially constant cross-sectional area. The corrugated channel, which receives the gasket, includes varying wide and narrow sections. The sealing feature provides for sufficient compression throughout the gasket and a tight, EMI-shielding seal formed between the pieces of the housing.
