Abstract

Here we report on the recent progress of the highly stable optical pulsed Timing Distribution System (TDS) commissioned at the geodetic observatory in Wettzell (Germany). The system connects a master clock (H-maser) to a mode-locked femtosecond-laser, which in turn uses delay compensated fiber lines for the coherent transmission of time and frequency. In order to use time itself for sensitive delay compensation, we developed a new generation of electronic interfaces for the generation and distribution of Pulse-Per-Second (PPS) signals with sub-ps stability, a low temperature coefficient (1ps/°C) and a constant delay with respect to the master reference. For the interfacing to the respective measurement systems, a set of required standard RF-Signals (5, 10, 100 MHz) with low phase noise (-160 dBc/Hz at 10kHz) and high fractional frequency stability (Allan Deviation 8x10-14 in 1s) are provided. This indicates that the system indeed distributes the stability of the master clock without penalties, which is equivalent to having a true copy of the master clock in perfect synchronization at each end point.
