Abstract
A packaging method and apparatus that improve the yield and reliability of multi-port fiber optical devices are disclosed. The method utilizes a flexible metallic connection between a solid frame holding input and output optics (including fibers, collimators) and the main body of an optical device. Optical alignment and realignment are accomplished following the soldering and/or hermetically sealing of the entire package. A flexible connection is made with permeable material that has minimum stress memory associated with realignments and can tolerate repeated adjustment or realignment without becoming structurally unsound.
