【摘要】 对4.25 Gbps小型化可热插拔(SFP)光收发模块的关键参数进行了理论分析,从发射、接收和控制3个方面讨论了模块的结构组成,设计出了符合SFP MSA及SFF-8472协议的光模块,并根据此设计方案制作了样品模块。在-40,25,85℃环境温度下测试和分析了模块的性能指标,结果显示其光功率、消光比和灵敏度等均符合设计要求,且在适用温度范围内表现出良好的稳定性。实验证实了方案的可行性,为模块的产品化提供了参考。更多还原

【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.更多还原
