Proof-of-Concept of a Fiber-Optic Timing Transmission for a Synthesis Radio Telescope

A fiber-optic timing transmission system for a synthesis radio telescope is under development. To achieve a high measurement precision and reduce a signal processing load, the adoption of BOC signals has been considered. The proof-of-concept results confirmed that the possibly of the measurement precision at the ps level and the repeatability of the systematic delay at the sub-ns level.
