Abstract
Optical carrier power fading is a severe problem in radio-over-few-mode-fiber (RoFMF) direct-detection system. We propose a novel method to mitigate the issue of carrier power fading. By analyzing the property of mode coupling in a few-mode fiber, our method is to utilize the linear mode coupling. The method successfully reduces the interference among optical carriers without increasing complexity, achieving the estimated throughput of 114.71 Gbps in the RoFMF system with 1.7-m FMF and 3-m wireless transmission.
