optical pumping signal的意思|示意

A Raman optical pump source 208 that generates a Raman optical pumping signal is optically coupled into the optical fiber span 206 with an optical coupler 210.

产生拉曼光泵浦信号的拉曼光泵浦源208通过光耦合器210被光耦合进入光纤段206。

The Raman optical pumping signal can exceed Class 1 M limits and, in fact, can have a much higher optical power than the optical data signal.

拉曼光泵浦信号可以超过1M级界限，实际上，可以具有比光数据信号明显高的光功率。

The filtered portion of the Raman optical pumping signal is then detected by the optical detector 224, 320.

然后，通过光检测器224，320检测经滤波的部分拉曼光泵浦信号。

In many optical communications systems, the Raman optical pumping signals exceed Class I m limits and have significantly higher power levels than the optical data signal.

在许多光通信系统中，拉曼光泵浦信号超过1 M级界限并具有比光数据信号明显高的功率级。

In other embodiments, the optical pumping signal counter-propagates in the optical fiber span with the optical data signals.

在其它实施例中，光泵浦信号在光纤段中与光数据信号反向传播。

The optical coupler 424 launches the Raman optical pumping signal in a direction that co-propagates with the optical data signals that are generated by the optical source 402.

光耦合器424沿着与光源402产生的光数据信号同向传播的方向发射拉曼光泵浦信号。
