An electro‐optical RF‐clock‐distribution system for 2998.01 MHz is presented. An added timing jitter of 5 fs RMS and a clock drift of 9.5 fs RMS over 24 h have been measured. The RF signal is distributed through a transmitter–receiver topology as intensity modulation on a CW laser at 1550 nm. Temperature‐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. © 2011 Wiley Periodicals, Inc.
