Abstract: front page image
(EN)The invention relates to an optical fiber 1 comprising a core 2 and a cladding 3 surrounding the core 2 and having an outer diameter of 125μm, the optical fiber 1 comprising a cured primary coating 4 directly surrounding the cladding 3 and a cured secondary coating 5 directly surrounding the cured primary coating 4, said cured primary coating 4 having a thickness t1 between 10 and 18μm and an in-situ tensile modulus Emod1 between 0.10 and 0.18 MPa, said cured secondary coating 5 having a thickness t2 lower or equal to 18μm and an in-situ tensile modulus Emod2 between 700 and 1200 MPa, wherein said first and second thicknesses and said first and second in- situ tensile moduli satisfy the following equation: 4% < (t1 x t2 x Emod1x Emod2 3) / (t1_norm x t2_norm x Emod1_norm x Emod2_norm 3)< 50%
(FR)L'invention concerne une fibre optique 1 comprenant un cœur 2 et une gaine 3 entourant le cœur 2 et ayant un diamètre externe de 125 µm, la fibre optique 1 comprenant un revêtement primaire durci 4 entourant directement la gaine 3 et un revêtement secondaire durci 5 entourant directement le revêtement primaire durci 4, ledit revêtement primaire durci 4 ayant une épaisseur t 1 entre 10 et 18 µm et un module d'élasticité en traction in situ Emod 1 entre 0,10 et 0,18 MPa, ledit revêtement secondaire durci 5 ayant une épaisseur t 2 inférieure ou égale à 18 µm et un module de traction in situ Emod 2 entre 700 et 1200 MPa, lesdites première et seconde épaisseurs et lesdits premier et second module d'élasticité en traction in situ satisfaisant à l'équation suivante : 4% < (t1 x t2 x Emod1x Emod2 3) / (t1_norm x t2_norm x Emod1_norm x Emod2_norm 3)< 50%
