As this equation reveals, efferent coupling works against a package's stability: the more a package relies on other packages, the more susceptible it is to ripple effects in the face of change.
The alignment of laser beam to fiber end face and degradation of beam quality can increase the coupling losses. This paper analyzes their effects to the coupling efficiency.
激光与光纤的机械对准误差和光束质量下降导致了耦合损失，本文分析了它们对耦合效率的影响。
