光信噪比 meaning in English
optical signal to noise ratio
osnr optical signal noise ratio
snro signal to noise ratio for optics
Examples
- Optical signal to noise ratio
光信噪比 - Secondly , we simulate the transmission process in computer , calculate the optical - signal - to - noise - ratio ( osnr ) of output signal with the same input signal filtered by the ofbg , matched filter and f - p filter , analyze the improvement of the osnr after filtered by them . we find it also has advantage over f - p filter . taking the two reasons into account , we believe that the weak ofbg is superior to the widely used f - p filter
另外用计算机模拟计算了光信噪比的改善情况，研究发现：一个相同的噪声信号经弱ofbg后的光信噪比较经过f - p滤波器后的光信噪比高，由此认为， ofbg用作光滤波器对接收端前置光放大器的噪声进行滤波，比常用f - p光滤波器具有更大的优越性。
