Abstract: A method and device are provided for measuring the viscoelastic characteristics of polymeric coatings of optical fibers directly on a coated fiber. The ends of the fiber are inserted into a pair of clamps which are shaped in such a way as to hold the coating without tearing it and to allow it to slide longitudinally over the fiber, and are associated with means for imparting them a relative oscillating motion to apply to the coating a longitudinal tensile stress of periodically varying intensity. The clamps and the means to impart them the oscillating motion are part of a rheometer which measures the opposing stress and processes the stress data to give the desired characteristics.
