As the core module in optical communication system

the optical transceiver module achieves the core function of converting electrical signals into optical signals and optical signals into electrical signals. Its performance plays a decisive role in the overall communication quality. This paper proposes an improved high-speed

low power consumption

low-cost 4-channel 25 Gbit/s optoelectronic interconnect transceiver module package design. Based on the traditional driver chip and modulator as the transmitter and the detector and trans-impedance amplifier as the receiver

we add a clock data recovery circuit to the transceiver module and optimize the package structure

and improve link performance by suppressing link jitter and reducing reflection caused by impedance mismatch at the same time. The back-to-back eye diagram test results of the optimized transceiver module show that the error rate of the system is below 1 E-13 at 25 Gbit/s

and the total power of the transceiver module is only 3.9 W.
