Absolute phase synchronization over optical fiber
Abstract:
An absolute phase synchronization method based on phase-conjugation scheme is demonstrated. A repeatable phase difference regardless of restart operation and fiber route changing between the phase standard at local site and the recovered signal at the intermediate-access node is achieved. This indicates that absolute phase synchronization to arbitrary nodes along the fiber link is feasible. At the intermediate-access node, this phase difference is highly stable with a fluctuation of ±0.014 rad over 10000s. And this phase difference shows consistency within 2% of the full cycle under different situations such as restart operation and fiber route changing.

Phase Changes
A substance melts or freezes at a temperature called its melting point and boils or condenses at its boiling point. These temperatures depend on pressure. High pressure favors the denser form of the substance, so typically, high pressure...
