Abstract

We report on a fully bidirectional 680 km fiber link connecting two cities for which the equipment, the setup, and the characterization are managed for the first time by an industrial consortium. The link uses an active telecommunication fiber network with parallel data traffic and is equipped with three repeater laser stations and four remote double bidirectional erbium-doped fiber amplifiers. We report a short-term stability at 1 s integration time of 5.4×1016 in 0.5 Hz bandwidth and a long-term stability of 1.7×1020 at 65,000 s of integration time. The accuracy of the frequency transfer is evaluated as 3×1020. No shift is observed within the statistical uncertainty. We show a continuous operation over five days with an uptime of 99.93%. This performance is comparable with the state-of-the-art coherent links established by National Metrology Institutes in Europe. It is a first step in the construction of an optical fiber network for metrology in France, which will give access to an ultrahigh performance frequency standard to a wide community of scientific users.

OC, optical coupler; FM, Faraday mirror; AOM, acousto-optic modulator; PC, polarization controller; PD, photodiode; PLL, phase lock loop; CTL, control. The tracking oscillators used after each photodetection are not shown in this picture. The pink rectangle represents the temperature-controlled box.

Fig. 4. Fractional frequency instability calculated from data recorded with Λ -counter and 1 s gate time versus averaging time. Dark red squares, modified Allan deviation for a compensated 200 km laboratory link; light red circles, modified Allan deviation for the free-running 200 km laboratory link; dark green stars, modified Allan deviation for a short link to estimate the noise floor of the RLS; light green diamonds, modified Allan deviation for the free-running short link.

Blue trapezes are the OADMs. For each span, we provide the span length and the span losses. We remotely supervise and optimize four double bidirectional EDFAs and three RLSs. Red lines refer to the ultrastable signal.
