Abstract
In this paper, a novel phase–time block coding (PTBC) approach incorporating an optical in-phase/quadrature (IQ) modulator for dispersion-induced power fading mitigation is proposed in a broadband intermediate-frequency-over-fiber (IFoF) system. The multiband IFoF signal is modulated simultaneously into in-phase and quadrature components by the IQ modulator while ensuring orthogonality with the PTBC to mitigate the effect of dispersion-induced power fading. The feasibility of the proposed technique is demonstrated using a 20 GHz-bandwidth IFoF signal transmission simulation in the fading-affected band of a 20 km dispersive fiber. In addition, proof-of-concept experiments are conducted using a 9.5 GHz IFoF signal and a 50 km dispersive fiber.
期刊介绍：
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
