multiplexing amplifier 中文意思是什麼
-
Raman fiber amplifier （ rfa ） is a kind of optical amplifier that can amplify signal light directly through nonlinear interaction of high intensity pump and signal light in fiber. whereas the spectrum of raman gain coefficient of optical fiber is not flat, the gain of signal light with different wavelength induced by a single pump is rather different, when wavelength division multiplexing ( wdm ) signal light is amplified by a single pump, the gain spectrum of the wdm signal light is not flat. the flatness of the wdm signal light has important impact on the optical signal - to - noise ratio ( osnr )
拉曼光纖放大器（ ramanfiberamplifier ，簡稱rfa ）利用高強度的泵浦光與信號光在光纖中的非線性相互作用實現信號光的直接放大，但是由於光纖的拉曼增益系數譜很不平坦，所以同一泵浦光源對不同波長信號光的增益就存在很大的差別，因此，用單泵浦光源來放大波分復用（ wavelengthdivisionmulti - plexing ，簡稱wdm ）信號光時，各信號光的增益值就有很大差異， wdm信號增益的平坦度對光信噪比（ opticalsignal - noiseratio ，簡稱osnr ）有重要影響。 -
