LD (laser diode) transceivers are very effective in reducing optical subscriber systems cost because they act as transmitters and receivers. This paper proposes a new transceiver switching circuit configuration, and two techniques for suppressing and canceling the discharge current effect of laser diodes. The new techniques, including mounting substrate optimization such as high-isolation and low parasitic capacitance, yield a high-performance LD transceiver module with the minimum average receiving optical power level of -37.0 dBm and a wide dynamic range of up to 25 dB for burst mode optical input at 29.0 Mb/s
