详细分析了光纤连接器的传输特性，计算了不稳定散斑图引起的非线性畸变和噪声。对于相干和部分相干激光源，确定了传输损耗的波动幅度及其相对于激光源波长位移的灵敏度。由于光纤连接器产生的非线性失真产生二阶谐波失真，对于单纵模注入激光器通常为- 36db，对于多模激光器通常为- 65db。对低频和高频波动的噪声性能也进行了估计。
The transmission characteristics of optical fiber connectors are analyzed in detail in order to calculate nonlinear distortions and noise due to instable speckle patterns. The fluctuation amplitude of the transmission loss and its sensitivity, with respect to a wavelength shift of the laser source, are determined for coherent and partially coherent laser sources. Nonlinear distortions due to fiber connectors yield a second-order harmonic distortion of typically -36 dB for a single-longitudinal mode injection laser, and typically -65 dB for a multimode laser. The noise performance has also been estimated for both low frequency and high frequency fluctuations.
