摘要： An optical communication cable includes a jacket having an interior surface that defines a cable jacket internal cross-sectional area and a plurality of optical fibers, wherein less than 60% of the cable jacket internal cross-sectional area is occupied by the cross-sectional area of the plurality of optical fibers. A scaffolding structure is provided adjacent to and supporting the jacket such that when the jacket is subjected to a burn and melts, the melted jacket material bonds to the scaffolding structure rather than sloughing off.

摘要： A method and an arrangement in a coating line for a fibre-like product or fibre-like products, in which the fibre-like product is directed from output means to a press head, by means of which a tube is formed around the fibre-like product. The fibre-like product is directed from the coating line to a feed unit in a preparatory position at the side. When the coating process of a previous product has terminated, the feed unit is shifted to the coating line and the fibre-like product is fed into the press head and is accelerated to the speed of the tube by means of the feed unit. The feed unit is detached from the fibre-like product, when measurement parameters associated with the fibre-like product and/or the tube reach the predetermined values and is shifted back to the preparatory position at the side of the coating line.

摘要： An improved method of coating an optical fiber is disclosed. A transducer is submerged in a container of liquid coating material and activated so that it causes the formation of a wave of coating material within the container. The optical fiber is then drawn through the container and through the wave, the wave counterbalancing the negative meniscus produced by drawing the fiber through the container. A curved housing also may be placed in the container and surrounding the transducer for controlling the size, amplitude, shape, or direction of the wave. A plurality of transducers also advantageously may be used.
