Paper Abstract

In order to meet the increasing requirement of accurate time synchronization in the “single-fiber one-way” fiber optic WDM-network, a one-way dual wavelength time transfer scheme based on the temperature-induced variations of group velocity dispersion (TIVGVD) is proposed. We set up a model of one-way time transfer by using time delay difference of dual wavelength to reversely derive the one-way delay variations with the help of Sellmeier expression. The influence of wavelength difference and temperature on one-way delay variationsis simulated and analyzed. The impact of wavelength drift and temperature estimation error on measurement accuracy is studied, which provides quantitative guidance on experimental research and application of one-way time transfer.
