Abstract :
An investigation by the Jet Propulsion Laboratory (JPL) into the fiber-optic distribution of a 100-MHz timing signal derived from a single hydrogen-maser (H-maser) to the several antennas at a deep space network (DSN) site is discussed. An evaluation of the performance of fiber-optic transmitters and receivers is given. Studies of phase-noise spectral density characteristics and the linearity of three 1300-nm semiconductor laser transmitters and three receivers are discussed. Vibration tests are discussed. It is concluded that using fiber-optic systems to distribute, without degradation, the 100-MHz frequency standard to all antennas located at a DSN site is a viable procedure with the quality of optical transmitters and receivers currently available
