High-Precision Radio Frequency Transmission using 4-core Fibers
We presents a radio frequency (RF) transmission system based on multi-core fiber (MCF), proving that RF transmission based on 4-core fiber with no frequency conversion methods in the roundtrip transmission can reach the stability of 7.15 E-18@10000 s, outperforming the RF transmission in standard single-mode fiber (SSMF) with similar conditions. In addition, the results of simultaneous transmission of data signal and frequency signal show that data signal transmission has only small influence on frequency synchronization.
