  • Optical fiber
    Publication number: 20060228083
    Abstract: Optical fiber capable of controlling attenuation losses caused by microbending on the signal transmitted thereby. The optical fiber comprises: a) an internal glass portion; b) a first coating layer of a first polymeric material surrounding said glass portion; and c) a second coating layer of a second polymeric material surrounding said first coating layer, wherein said first polymeric material has a hardening temperature lower than ?10° C., an equilibrium tensile modulus lower than 1.5 MPa, wherein said first coating layer has a thickness of from 18 ?m to 28 ?m and wherein said second coating layer has a thickness of from 10 ?m to 20 ?m.

  • Method for controlling microbending induced attenuation losses in an optical fiber
    Publication number: 20050207715
    Abstract: A method for controlling attenuation losses caused by microbending on the signal transmitted by an optical fiber having an internal glass portion. A first coating layer of a first polymeric material surrounds the glass portion and a second coating layer of a second polymeric material surrounds the first coating layer. The first polymeric material has a hardening temperature lower than 10° and an equilibrium modulus lower than 1.5 MPa.
