Abstract
We demonstrate transmission of narrow-linewidth cw laser light (1535 nm) from a cavity-stabilized fiber laser over 251 km of single-mode optical fiber (76 km installed and 175 km on spools). Using standard Doppler-cancellation techniques, we transmit the light with a residual frequency instability of 3 x10-16 at 1 s averaging time and better than 6 x 10-19 at 100 s. This paper gives the practical experimental details that enabled this record distance and instability result. We find our ability to transmit over increased distances is limited by the transit time of the fiber and the environmentally induced fiber phase noise.Proceedings Title
