To develop highly reliable fixed wireless links, such as mobile backhaul and fronthaul systems, it is essential to evaluate the link budget under extreme weather conditions. In this paper, we presented a link budget evaluation for fixed wireless link

Millimeter wave fixed wireless systems in future backhaul and access network applications can be affected by weather conditions. The losses caused by rain attenuation and antenna misalignment due to wind-induced vibrations have greater impacts on the

We demonstrated a high-performance dual-color B5G DRoF system using delay compensation. A quad-level 6-Gbit/s 64-QAM OFDM signal was successfully transmitted over the proposed system, showing a much better performance compared to the conventional 1-b

Based on the use of a dual-wavelength controlled quasi-color-free laser diode (QCFLD) transmitter with either destructively interfered beating or single-sideband filtering after receiving at a remote node, the 100-km long-reach (LR) carrierless milli

To investigate the tolerance of laser linewidth, a stable and variable light source is essential. This study proposes a novel method for generating a variable linewidth and variable light source using a lithium niobite phase modulator, achieved throu

By using a 512-quadrature amplitude modulating-orthogonal frequency division multiplexing (512-QAM OFDM) data stream with universal filtered multicarrier (UFMC) process to directly encode a quasi-color-free laser diode (QCFLD) with dual-mode carrier,

An OSR-reduced quad-level delta-sigma modulated 32-QAM OFDM based RoF link was experimentally demonstrated. The 2-Gbit/s data was transmitted over 25-km SMF with OSR reduced to 15 at receiving power of −9 dBm.

A quasi-color-free laser diode (QCFLD)-based 60-Gbit/s long-reach (LR) OFDM-PON with dispersion management is demonstrated. After injection locking, the QCFLD achieves an ultimate back-to-back transmission capacity of 60 Gbit/s. After propagating thr
