Description / 详细描述
该 1310nm DFB 10Gigabit SFP+ 收发器设计用于在单模光纤上传输和接收光数据，链路长度可达 10km。
SFP+ LR 模块电气接口符合 SFI 电气规范。发射器输入和接收器输出阻抗为 100 Ohm 差分。数据线内部 AC 耦合。模块提供差分终端并减少差分到共模转换，以实现高质量信号终端和低 EMI。SFI 通常在 200mm 改进型 FR4 材料上运行，或在带一个连接器的约 150mm 标准 FR4 上运行。
发射器将 10Gbit/s 串行 CML 电数据转换为符合 10GBASE-LR 标准的串行光数据。提供开路集电极兼容的 Transmit Disable（Tx_Dis）。该引脚上的逻辑”1″或不连接将禁用激光器发射；逻辑”0″提供正常操作。发射器具有内部自动功率控制环路（APC），确保在供电电压和温度变化下恒定的光功率输出。提供 TX_Fault 输出，高电平表示模块发射器检测到与激光器操作或安全相关的故障条件。
接收器将 10Gbit/s 串行光数据转换为串行 PECL/CML 电数据。提供 Rx_LOS（信号丢失）输出，高电平表示光信号电平低于相关标准规定值。建议对发射器和接收器均进行电源滤波。
