Implication

Experimental analysis demonstrates fundamental limits to optical frequency stability across fiber-optic links up to 251 km, indicating bidirectional single-fiber transfer optimizes precision.

Key Points

Quantify technical and fundamental limitations on phase noise, timing jitter, and frequency stability during coherent optical frequency transport across long fiber-optic links.
Formulated theoretical models for achievable phase noise and frequency stability in optical carrier transmission.
Tested coherent transfer experimentally across fiber-optic links ranging from 38 km to 251 km.
Compared bidirectional transfer along a single fiber against two-way transfer over separate outgoing and return fibers.
Bidirectional transfer on a single fiber achieved short-term frequency instability reaching the fundamental limit of delay-unsuppressed phase noise, which scaled as link length to the 3/2 power.
Two-way transfer using separate outgoing and return fibers exhibited severe instability constrained by differential fiber noise.
