4.25 Gbps小型可热插拔光收发模块的设计与测试

Abstract

By taking 4.25 Gbps Small Form-factor Pluggable(SFP) as an example,this paper analyzes theoretically its key parameters in detail,and discusses the module structure composition from the transmitter,receiver and the control part.Then it designs the optical module according to the SFP MSA and SFF-8472 agreement.On the basis of the design,some sample optical transceiver modules are designed.Finally,the optical power,extinction ratio,sensitivity and other performance indicators of the module are tested at-40,25,85 ℃,and results indicate that these parameters meet the design requirements,and show good stability in a suitable temperature range.The feasibility of the design is confirmed by experiments,which provides a reference for the actual production of modules.
