Abstract

Full-duplex mobile fronthaul (MFH) architecture with a colorless remote radio unit (RRU) and further RRU (F-RRU) based on radio over fiber technology (F-RRU) is proposed. Such MFH architecture can carry out low- and high-frequency hybrid networking for common seamless wide coverage and high data rate requirements in hotspot areas. Optical millimeter-wave signal is abstracted by an interleaver in the RRU and then is transmitted to multiple F-RRUs. The polarization multiplexing technology and power splitters employed make the RRU and F-RRU free from the laser sources, as the uplink optical carrier is abstracted from the downlink. Simulations are conducted to demonstrate the reliability of the proposed MFH architecture, and results show that the radio signals maintain strong performance after standard single mode fiber transmission.
