Abstract. A method for simultaneous determination of the optical fiber parameters by a direct measurement of the differential delays between the first several waveguide modes is experimentally realized by utilization of a femtosecond dye laser synchronized with a streak camera. Identification of the waveguide mode within the temporal structure of the radiation is made. The precision of the measurement is of sufficient quality to warrent industrial testing of optical fibers.
