Signal Integrity Design For QSFP interface applicated in RF Optical transmitter Module

摘要：

　　The QSFP interface is used as the input port in the design of 4*10GHz optical transmitter module.It will inevitably lead to impedance mismatch,resonance and signal distortion.Using the three-step optimization,in DC-10GHz bandwidth,the insertion loss S21 is greater than-2dB,and the echo loss S11 is less than-10dB,the S-parameter resonances were largely mitigated.Finally,The whole schematic link of transmitter module with the optimized QSFP interface is modeled and simulated by ADS,the gain flatness of the transmission link is within ±4dB,and shows that the optimized QSFP interface has a perfect electrical performance in the optical transmitter module.
