Abstract

By using impedance (Z) matching circuits in a low-cost transistor outline (TO) CAN package for a 10Gb/s transmitter, we achieve a cost-effective and small bidirectional optical subassembly (BOSA) with excellent optical transmission waveforms and a > 40% mask margin over a wide temperature range (-10 to 85°C). We describe a design for Z matching circuits and simulation results, and discuss the advantage of the cost-effective compensation technique.
