20-Gbaud QPSK optical and radio transmission using high-gain antennas for resilient access networks

Abstract

20-Gbaud QPSK transmission over 20-km SMF for optical and 7.5-m free space for 90-GHz radio is successfully demonstrated with 50-dBi Cassegrain antennas. This configuration will be feasible for kilometer-order distance transmission.
