MCP 的开口面积与总有效面积之比。
开路电压是负载电阻无限大时产生的光伏电压,表现出与器件的受光面无关的恒定值。
这是未施加任何反馈的运算放大器的增益,表示输出电压与输入电压的比。单位为 dB。
反射的返回光与入射光的比。如果反射的返回光量高,则发射侧的激光二极管振荡将变得不稳定,导致相对强度噪声增加。因此,必须最大限度地减少反射的返回光量。插座型模块中针对此问题通常的解决方案是,在光路中插入一个光隔离器或称为“插芯”的套管(该元件的光纤插入端被抛光以进行物理接触,器件端被倾斜抛光)以最大限度地减少光回波损耗。
这是光电传感器器件的最大光输入功率。当超过给定量的光进入光电传感器器件时,光电二极管或放大器变得饱和。这会干扰输出波形,导致无法正确接收光信号。
