Distributed coherent optical OFDM multiplexing using fiber frequency conversion and free-running lasers
TL;DR: In this article, a distributed coherent optical orthogonal frequency division multiplexing by fiber-frequency conversion for locally-defined exact channel mapping based on free-running lasers is proposed, and experiments with quadrature phase shift keying and 16-quadrature-amplitude modulation subchannels show error-free performance.
