An automated fiber alignment, fixing, and sealing process was developed for optoelectronic devices produced by BT&D Technologies. The products -- transmitters, receivers, etc. -- were developed simultaneously with the process, allowing development of common technologies and submodule "building blocks." This approach has many advantages: sufficient manufacturing volume to justify automation, quick response to new product variations, and uniform quality. This paper describes the development of a patented laser-based manufacturing system for pigtailing optoelectronic devices.
