Abstract
We propose and demonstrate conjugated RoF (C-RoF) secured by physical layer encryption with deliberate signal randomization, for high-RF-link-gain and high-security analog RoF transmission. 19.4-dBm high-power secured C-RoF-QPSK is experimentally achieved with improved fiber nonlinearity tolerance.
