We present optical frequency transfer over deployed multi-core fiber at levels that support the world's best optical clocks for the first time, achieving fractional frequency stability better than 3×10-19 through 25.2 km of fiber.

Abstract

We present optical frequency transfer over deployed multi-core fiber at levels that support the world's best optical clocks for the first time, achieving fractional frequency stability better than 3×10-19 through 25.2 km of fiber.
