Abstract

Ultra-high-definition applications will be one of the main drivers for emerging 5G communications. 5G supports higher data rate utilizing higher frequency bands than those in existing cellular systems. However, higher-frequency radio waves have higher directionalities, resulting in decreased indoor coverage. Therefore, radio-over-fiber (RoF) systems are needed for indoor distribution of wireless signals. Recently, we developed a graded-index plastic optical fiber (GI POF) that enables higher-quality RoF transmission than conventional multimode fibers for short-distance links (<100 m). The GI POF can reduce noise and distortion in RoF transmission through its strong mode coupling. Here, we demonstrate that the GI POF significantly increases fiber-misalignment tolerance in RoF transmission. The GI POF will realize do-it-yourself optical fiber connections for indoor applications.
