“…The next generation of integrated fiber-wireless access networks has been in pressing need of low-cost and highcapacity deployment to meet user demand. 1,2 Recently, some new hybrid access networks have been reported, such as optical metro access network based on low-cost optical multicarrier, 3 and high-capacity free space opticsbased passive optical network (FSO-PON) for 5G front-haul deployment. 4 As a converged access system that combines radio-overfiber (RoF) wireless access technology and PON wired access technology, RoF-PON embodies the advantages of both.…”

The unique advantage of orbital angular momentum (OAM) provides a novel approach to breaking through the limitations of high‐capacity and long‐distance transmission in the conventional radio‐overfiber passive optical network (RoF‐PON) hybrid access network. Introducing the OAM division multiplexing (OAM‐DM) based on Laguerre–Gaussian (LG) beams into the RoF‐PON, an innovative multidimensional system architecture is proposed, which integrates with polarization‐division multiplexing (PDM), wavelength‐division multiplexing (WDM), and orthogonal frequency‐division multiplexing (OFDM) technologies. Successful long‐distance transmission of both the downstream 40 GHz radio OFDM signal and the upstream 40 Gbps on‐off keying (OOK) signal over 80 km are achieved. Additionally, at the optical network unit side, low‐cost upstream carrier re‐modulation technology and flexible access for both wired and wireless signals are realized. The proposed RoF‐OAM‐DM‐PDM‐WDM‐OFDM‐PON architecture offers a dependable solution for high‐capacity and low‐cost future communication systems, holding great importance in achieving flexible access networks.

“…With the rapid growth of data volume due to the mass proliferation of smart mobile devices, the beyond fifth-generation (B5G) and the sixth-generation (6G) wireless communication systems will exploit the high frequency band to circumvent the congested spectrum resource, which leads to a substantial increase of wireless cell sites to achieve seamless signal coverage [1]. RoF technology is a potential candidate to simplify the base station architecture and reduce the power consumption.…”

A method to compensate for the dispersion-induced power fading in a radio-over-fiber (RoF) link is proposed and experimentally demonstrated based on stimulated Brillouin scattering (SBS). In the central office, a part of the optical carrier is used to generate frequency-definable two-tone pump light via carrier-suppressed double-sideband modulation. The two-tone pump light generates both Brillouin loss and gain spectra at the vicinity of the optical carrier when it counter-propagates with the signal light in a spool of single-mode fiber (SMF) located in the central office. Hence, the relative phase difference between the optical carrier and the ±1st -order modulation sidebands of the signal light can be freely varied by using the SBS-induced carrier phase shift, which can compensate for the power fading induced by the group-velocity dispersion in the transmission fiber between the central office and the base station. In the experiment, a flat gain in the frequency range of 10 MHz to 10 GHz is achieved for the signal transmission over 45-km SMF. The error vector magnitudes (EVMs) of the transmitted 64 QAM signals centered at 4.8 GHz and 5.0 GHz are greatly improved after dispersion-induced power fading compensation.
