摘　　要：通过实验测量和计算 ,得出各种类型光接收组件输给下级放大模块的有效净输出电平值 ,并根据此电平的高低把光接收组件分为低电平输出型、中电平输出型和高电平输出型 3类。同时还得出在低光功率接收时 3种光接收组件类型的光接收机造成全系统载噪比指标降低的规律。Optical receiver components can be classified into three types, including low medium and high level output, in terms of the net output level feeder to the hind modules, which can be calculated and measured through experiments.It can conclude the rules that in low level output three types optical receiver affect the whole system ratio.

关 键 词：光接收组件 低电平输出 中电平输出 高电平输出
