Synthetic silica claddings and hard coatings are applied to optical fibers to eliminate internal faults and to prevent the fibers from being damaged during proof tests, respectively. These fibers are subjected to proof tests ar 2.2% strain, and an average passing length of 19 km is obtained as a result. Moreover, it is clarified that the contribution of the hard coatings during proof tests can be adequately determined by using the Young's moduli obtained by dynamic mechanical measurements.
