Full-Duplex Analog Photonic Fronthaul Link With Carrier Reuse at 25 GHz for 5G and beyond
Original language description
This letter proposes a full-duplex analog fronthaul seamless transmission system employing wavelength reuse for simultaneous downlink (DL) and uplink (UL) signal data streaming at 25 GHz frequency band. The proposed architecture integrates centralized optical sources at a central office (CO), an optical distribution network (ODN) comprising 10 km of standard single-mode fiber (SSMF) and a 1.9 m long free-space optical (FSO) link, and a remote radio head (RRH) utilizing 1.9 m long wireless radio links. Intensity modulation is used for DL, while phase modulation combined with optical filtering enables efficient carrier reuse and data modulation for UL. The system’s performance is assessed using orthogonal frequency-division multiplexing (OFDM) signals with 64-quadrature amplitude modulation (QAM) and quadrature phase shift keying (QPSK) modulation for DL and UL. Results demonstrate low error vector magnitude (EVM) across various input and received optical power levels, with minimal penalties from fiber dispersion and bidirectional reflections. The study also evaluates the impact of nonlinearities, phase noise, and intermodulation distortions, showcasing the system’s robustness. This scalable, efficient solution advances full-duplex optical fronthaul networks and supports millimeter-wave (mmW) applications beyond 25 GHz.
