摘要： Device and method for chemical deposition on an elongated member of vitreous material in which a rotating gripping member causes a first end portion of the elongated member to rotate. The second end portion of the elongated member is borne by a pair of supporting members which are axially spaced apart (L1) and are capable of permitting angular rotational movement and axial sliding of the second end portion. Each supporting member also applies a radial constraint preventing the second end portion from moving away from the axis of rotation, thus forcing the second portion and the elongated member to lie with a longitudinal axis coaxial with the axis of rotation. Any curvature of the elongated member is corrected and recovered in this way.

摘要： An optical cable for telecommunications having an optical core and a plurality of protecting and reinforcing elements or avers placed around the optical core. The optical core has a central reinforcing element, a polymer layer, a plurality of optical fibers incorporated in the polymer layer and a thin sheath which covers the polymer layer. The optical fibers have an alternating spin about their own axes with a maximum value of at least 4 twists per meter, and a core having a mean ellipticity in the range of 0.25 to 0.55, in such a way that the effects of birefringence of the fibers caused by the cabling process are significantly reduced.
