| 8. | Moreover , the saturation characteristic of raman fiber amplifier is also one of the important parameters and the total power of signal light input into the fiber is limited by it 另外,饱和特性也是光放大器的重要指标之一,它限制了可以输入光纤的总信号光功率。 |
| 9. | 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 ) 拉曼光纤放大器( ramanfiberamplifier ,简称rfa )利用高强度的泵浦光与信号光在光纤中的非线性相互作用实现信号光的直接放大,但是由于光纤的拉曼增益系数谱很不平坦,所以同一泵浦光源对不同波长信号光的增益就存在很大的差别,因此,用单泵浦光源来放大波分复用( wavelengthdivisionmulti - plexing ,简称wdm )信号光时,各信号光的增益值就有很大差异, wdm信号增益的平坦度对光信噪比( opticalsignal - noiseratio ,简称osnr )有重要影响。 |
| 10. | Both of the numeric simulations and the experimentations indicate that the c band raman fiber amplifier can be satisfied with some gain flatness when numbers and wavelengths of pump are installed while powers of pump are arranged properly . the method of measuring fiber raman gain coefficient is adopted to other type 数值计算和试验上都证明了在合理地选取泵浦源的个数和波长的情况下,通过对各个泵浦功率配置的调整, c波段的拉曼光纤放大器可以满足一定的增益平坦度。 |
