Two-Way Optical Time and Frequency Transfer Over a 20-km Fiber Link Based on Optical Frequency Combs
Published 2019-01-01Get full textTraditional high-precision long-distance time–frequency transmission requires a complex compensation structure and a continuous optical link, which make high-precision transmission difficult. In this study, we use two counter-propagating optical frequency combs to realize high-precision t...

RF Transfer by Optical Comb Over 50-km Fiber Link With <inline-formula> <tex-math notation="LaTeX">$4.7\times 10^{-18}$</tex-math></inline-formula> Instability
Published 2016-01-01Get full textA radio-frequency (RF) dissemination system using an optical comb over a 50-km fiber link has been demonstrated in this paper. An optical filter is utilized to suppress the dispersion influence of the optical comb in the transfer fiber link. The compensation scheme, based on an electrical compensati...

High-Security Multi-Slot Chaos Encryption With Dynamic Probability for 16-CAP PON
Published 2020-01-01Get full textIn this paper, a high-security chaos encryption with dynamic probability for 16-carrier-less amplitude/phase (CAP) PON is proposed by using two-layer chaos map with feedforward neural network-based XOR operator (FNNXOR). The inner chaotic map is divided into several time slots, and the ke...

A Novel Multi-Level Constellation Compression Modulation for GFDM-PON
Published 2019-01-01Get full textIn this paper, for the first time, a novel multi-level constellation compression modulation (MCCM) is proposed and applied for generalized frequency division multiplexing passive optical network (GFDM-PON). The principle of the proposed MCCM is to transfer the constellation points of the outer circl...
