Abstract

An electro-optical system for a RF-clock-distribution with a temperature-drift and a vibration compensation is presented. An added timing jitter of less than 10 fs_RMS and a clock drift of 50 fs_RMS over 26 hours have been measured. The RF signal is distributed through a transmitter - receiver topology as intensity modulation on a CW laser at 1550 nm. The temperature and the vibration-induced fiber group-delay variations are compensated by adjusting the wavelength of the laser and making use of the fiber chromatic dispersion. The system uses standard commercially available telecommunication optical components.
