In this study, we used a single optical modulator to generate multiple path wireless and wired signals. We successfully transmitted two channels of 5 Gbaud quadrature phase-shift keying (QPSK) wireless signal and one channel of 5 Gb/s binary amplitude on-off keying (OOK) baseband signal over 80-km single-mode fiber (SMF). By employing dual-polarization Mach-Zehnder modulator, power divider, optical filter, and other devices, we realized the dual services of multi-channel wireless and wireline signals with high-frequency efficiency and simple structure. This method reduces the influence of signal interference and optical fiber dispersion effect, avoids the limitation of transmission distance, and improves the reliability of the system. The experimental results show that the power penalty of 5 Gb/s OOK baseband wireline signal after 80-km SMF transmission is only 1 dB, and the power penalty of 15 GHz and 30 GHz signals carrying 5 Gbaud QPSK after 80-km SMF transmission are 2 dB and 4 dB, respectively.
