III. SPECIFICATION DES CABLES DE GARDE A FIBRES OPTIQUES ET DE LEURS ACCESSOIRES

Les câbles à fournir comprendront 24 fibres optiques monomodes réparties comme suit :

• Huit (8) fibres optiques NZDSMF conformes aux recommandations UIT-T G 655
• Seize (16) fibres optiques SMF conformes aux recommandations UIT-T G 652

Ces fibres seront optimisées pour les fenêtres 1550 nm et 1310 nm pour la fibre G652, et 1550nm et 1625 nm pour la fibre G 655.

III.1 CARACTERISTIQUES TECHNIQUES DES FIBRES

III.1.1. Cœur et gaines optiques
Chaque fibre sera constituée d'un cœur en verre de silice. La gaine sera bien sellée contre le cœur et constituée également en verre de silice ou d'un matériau ayant un indice de réfraction légèrement plus bas.

III.1.2 Revêtement primaire
La fibre nue sera revêtue de résine traitée aux UV pour assurer la protection contre l'abrasion pendant la fabrication ultérieure
