Here we share the relevant data of the manuscript “Stability limitations of optical frequency transfer in telecommunication DWDM networks”.
The files:
“fig_2a_total.txt”
“fig_2a_diff.txt”
contains respectively the timeseries data of phase fluctuations of total delay and differential delay between two fibers in 50 km-long soil-deployed cable. Same results for 110 km-long aerial cable are in files:
“fig_2b_total.txt”
“fig_2b_diff.txt”
The files:
“fig_3_aerial_MDEV_points.txt”
“fig_3_soil_MDEV_points.txt”
contains respectively points of modify Allan deviation of the differential delay fluctuations in 110 km-long aerial and 70 km-long soil-deployed cable. For short averaging the stability is limited by the noise of time interval counter (MTC 108). Before MDEV calculations the differential delay fluctuations was divided by factor of two, as a half of these fluctuations is present at the output of a stabilized system.
The files:
“fig_4_soil_MDEV_points_CW-total.txt”
“fig_4_soil_MDEV_points_CW-diff.txt”
contains respectively points of modify Allan deviation of the total and differential delay fluctuations in 70km soil-deployed cable, measured with the unmodulated coherent optical carrier.
The files:
“fig_7a_EDFA_phase.txt” and “fig_7a_EDFA_temp.txt”
“fig_7b_Raman_phase.txt” and “fig_7b_Raman_temp.txt”
“fig_7c_ROADM_phase.txt” and “fig_7c_ROADM_temp.txt”
contains the timeseries data of simultaneous measurement of phase and temperature changes in individual cards (modules) of the DWDM system: EDFA amplifier, card containing the Raman module, as well as ROADM (Reconfigurable Optical Add Drop Multiplexer) module.
Time series data of the fluctuations of the total and differential propagation delay of the signal transfer in the unmodified DWDM system (over 1500 km long route) include files:
“fig_9_total_phase_fluct_part1”, “fig_9_total_phase_fluct_part2”, “fig_9_total_phase_fluct_part1”
“fig_9_diff_phase_fluct_part1”, “fig_9_diff_phase_fluct_part2”, “fig_9_diff_phase_fluct_part3”
The files:
“fig_10_mdev_acusticNOISE.txt”
“fig_10_mdev_air-conditioning_ON.txt”
“fig_10_mdev_air-conditioning_MODIFIED.txt”
contains points of modify Allan deviation that shows respectively: the influence of acoustic noise, stability of the frequency transfer in DWDM network in the case of sub-optimal (asymmetric) cooling within a single ILA node, while the last file shows the stability of the transfer after optimizing the airflow within this node.
