Optimization of a small to-can package electrical design for SFF/SFP optical transceiver modules

In this paper, we present an optimum TO‐38 package design for SFF/SFP optical transceiver modules in order to improve the 3‐dB bandwidth. The frequency response of the TO‐38 package is measured and compared to simulation where the 3‐dB‐bandwidth was 3.5 GHz. For a higher operating bandwidth (>15 GHz), new optimized physical geometries for the TO‐can package, such as bonding wires, leads, and material, are suggested. The optimal result of simulation shows that this TO‐can package can be used at a higher‐bit‐rate optical module of 10 Gb/s. © 2004 Wiley Periodicals, Inc.
