摘要	A method and apparatus of using an input signal from a single-transverse mode vertical-cavity surface-emitting laser (VCSEL) with a multimode fiber (MMF) link to enable improved stabilization in time variation and improved modal dispersion of the output signal to facilitate the use of adaptive equalization techniques. The improvement results from using a conditioned launch of the input signal from the VCSEL into the MMF link. The increase in performance may be measured by the improved impulse response and an improved bandwidth-distance product of the MMF link.
其他摘要	一种使用来自具有多模光纤（MMF）链路的单横模垂直腔面发射激光器（VCSEL）的输入信号的方法和装置，以改善时间变化的稳定性并改善输出信号的模态色散以便于使用自适应均衡技术。使用从VCSEL到MMF链路的输入信号的条件启动产生了改进。可以通过改进的脉冲响应和MMF链路的改进的带宽 - 距离乘积来测量性能的提高。
主权项	An apparatus for improving optical signal characteristics, the apparatus comprising: a single-transverse mode vertical-cavity surface-emitting laser (VCSEL) having an emitting aperture; a multimode fiber (MMF) link having an input end and an output end; and signal conditioning means coupled between said VCSEL emitting aperture and said input end of said MMF, said signal conditioning means effectively time stabilizing and modal dispersion controlling the optical characteristics of the output optical signal from the output end of said MMF link to enable adaptive equalization techniques to be applied to the output signal to improve the bandwidth of the output signal.
