An ultracompact, 2-cc-size, 0.64-W 2.5-Gbit/s optical receiver module combined with an MU receptacle

Summary form only given. Recently, optical communication systems have been applied to various field such as local area networks (LANs), optical interconnections, SDH/SONET, and wavelength-division multiplexing (WDM) systems. To achieve these systems cost-effectively, some trials have been made to realize low-power and small-size optical modules. We have developed an ultra-compact and low-power 2.5-Gbit/s optical receiver (OR) module based on a novel structure and advanced IC design. For drastic size reduction, we used the following design schemes: (1) a butterfly package merged with an MU receptacle (MU-R), (2) multichip module (MCM) technology for assembling ICs, and (3) advanced IC design to eliminate external components that obstruct size reduction.
