“…Therefore, the kernel of suppressing the dispersion-induced power fading is to eliminate this destructive interference. In [3][4][5][6], the dispersion-induced power fading is eliminated by controlling the relative phase difference between the optical carrier and the ±1 st -order modulation sidebands based on dual-parallel Mach-Zehnder modulators (DPMZMs), where the three direct-current (DC) bias voltages of the DPMZM or the polarization orientation before photodetection must be precisely adjusted. In [7,8], single-sideband (SSB) modulation is employed to generate a single electrical signal in the photodetector, which avoids the destructive interference, i.e., the dispersion-induced power fading.…”

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.

“…Several applications of fiber-radio schemes are reported in the literature. For instance, in [6], an all-optical link with double spectral-efficient transmission and compensation of chromatic dispersion-induced power fading is proposed and demonstrated experimentally. In [7], a system for the transmission of energy through an optical fiber is proposed.…”

Evaluation of the Digital Data Performance Transmission on a Fiber-Radio System

This work shows a set of numerical simulations to evaluate the digital data performance transmission for a fiber-radio system. For this goal, VPI Photonics software is used to simulate the transmission of a digital signal at a bit rate of 2.4 GHz through an optical link of 25 km of single-mode standard fiber (SM-SF). Whereas MATLAB software is utilized to emulate a wireless channel considering four main phenomena inherent to this channel, such as multipath and slow fading, co-channel interference, and additive white Gaussian noise (AWGN). The modeling carried out in MATLAB considers a user in movement within its coverage area cell. The constellation diagram, bit error rate (BER), and signal-to-interference-plus-noise ratio (SINR) statistical tests are used to evaluate the performance of this approach. This proposal finds potential applications in the field of cellular telephony, the Internet of Things (IoT), or any other communication system to evaluate the quality of the delivered signal to a user in motion within a particular coverage cell.
