We measure the relative core-core drifts of a 6.3 km installed multi-core fiber cable, reporting < 420 fs of relative drift over 9 h for all core combinations. The corresponding frequency noise is shown to be around 10 -4 and < 10 -5 [Hz 2 /Hz] at 1 Hz and 1 mHz, respectively.

Abstract
We measure the relative core-core drifts of a 6.3 km installed multi-core fiber cable, reporting < 420 fs of relative drift over 9 h for all core combinations. The corresponding frequency noise is shown to be around 10 -4 and < 10 -5 [Hz 2 /Hz] at 1 Hz and 1 mHz, respectively.File in questo prodotto:
