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 ≤ Δα ≤ -0.9. This serves to create a modal delay opposite to the chromatic modal dispersion. The compensation is achieved by using a select length of the compensating multimode optical fiber optically coupled to an output end of the primary multimode optical fiber. The compensating multimode optical fiber can be configured to be bend insensitive.
摘要翻译：公开了具有可调色散色散补偿的多模光纤系统，其中该系统包括VCSEL光源和一次和二次光耦合多模光纤。由于VCSEL光源具有径向变化的波长光谱，因此其与主多模光纤的使用产生减少带宽的色模色散。补偿多模光纤被设计为具有相对于主要多模光纤的α参数的差异为-0.1 <=Δαα= -0.9。这用于产生与色模色散相反的模态延迟。通过使用光耦合到主多模光纤的输出端的补偿多模光纤的选择长度来实现补偿。补偿多模光纤可以被配置为弯曲不敏感。
