摘要： A DC level detection circuit between high speed signal line connecting ports and a system using the same in optical communications is disclosed. Corresponding ports of a high speed signal line each have an additional resistor, where one additional resistor has a resistance significantly greater than that of the other resistor. The smaller resistor is grounded. The larger resistor is connected to a DC voltage source, a low pass filter, and a signal detection port. Thus, when both ports of the high speed signal line are connected, a status of the electrical level detected at the signal detection port changes. The circuit detects the connection state of the high speed signal line without negative effects on signal transmission and is applicable to various circuits, especially plug-in modules and corresponding slots. Thus, the circuit further enables signal port multifunctionality, increases module installation accuracy, and provides higher compatibility for plug-in modules.
摘要翻译：公开了高速信号线连接端口之间的DC电平检测电路和在光通信中使用该直流电平检测电路的系统。高速信号线的对应端口各自具有附加电阻器，其中一个附加电阻器的电阻显着大于另一个电阻器的电阻。较小的电阻器接地。较大的电阻器连接到直流电压源，低通滤波器和信号检测端口。因此，当连接高速信号线的两个端口时，在信号检测端口检测到的电平的状态改变。该电路检测高速信号线的连接状态，对信号传输没有负面影响，适用于各种电路，特别是插件模块和相应的插槽。因此，该电路进一步实现信号端口多功能性，增加模块安装精度，并为插件模块提供更高的兼容性。
