Using optical frequency multiplication to deliver a 17 GHz 64 QAM modulated signal to a simplified radio access unit fed by multimode fiber

摘要

Using optical frequency multiplication, simultaneous 3 GHz to 17 GHz carrier upconversion and 64-QAM modulation with low EVM (4.6 %) is demonstrated. A simplified fiber wireless access unit fed by 4 km multimode fiber is used.
