摘要： Multimode optical fiber systems with adjustable chromatic modal dispersion compensation are disclosed, wherein the system includes a VCSEL light source and primary and secondary optically coupled multimode optical fibers. Because the VCSEL light source has a wavelength spectrum that radially varies, its use with the primary multimode optical fiber creates chromatic modal dispersion that reduces bandwidth. The compensating multimode optical fiber is designed to have a difference in alpha parameter relative to the primary multimode optical fiber of -0.1
摘要翻译：公开了具有可调色度模式色散补偿的多模光纤系统，其中该系统包括VCSEL光源以及主和次光耦合多模光纤。由于VCSEL光源具有径向变化的波长谱，因此与主多模光纤的使用会产生色度模式色散，从而降低带宽。补偿多模光纤被设计成相对于主要多模光纤具有-0.1≤Δalpha≤0.9的α参数差。这用于产生与色度模式色散相反的模式延迟。通过使用选择长度的光学耦合到主多模光纤的输出端的补偿多模光纤来实现补偿。补偿多模光纤可以被配置成对弯曲不敏感。
