Optical fibre and optical fibre tape, and method for making same

The invention relates to apparatus for curing an object by using UV radiation, the object being made, at least in part, of a material that is cross-linkable under UV radiation, said apparatus including: UV radiation sources (2); a tube (3) made of a material that is permeable to UV radiation, the tube being surrounded by the UV radiation sources (2), and being designed to receive at least a portion of the object to be cured; and gas feed means for generating a gas flow (15) through the tube (3) along a general flow axis (9). According to the invention, the apparatus further includes channeling means (4) for causing a portion (16) of the gas flow (15) to constitute a gas screen sweeping the inside sidewall (5) of the tube (3).

Apparatus for curing by UV radiation

Polypropylene-polyethylene copolymer buffer tubes for optical fiber

A buffer tube for an optical fiber cable is made from a polypropylene-polyethylene copolymer resin having nucleating agents and filler materials disbursed therein. The nucleating agents and filler materials improve compression-tension resistance and thermal expansion properties of the polypropylene-polyethylene copolymer buffer tube.
