Définition du câble fo

Le câble à fibres optiques (câble FO) utilise des fibres de verre ou de plastique comme support de transmission des signaux optiques. Il remplace les câbles en cuivre dans la transmission des signaux électriques et offre une bande passante élevée, une faible perte et une forte résistance aux interférences.

Structure du câble fo

Noyau de fibre : une fine fibre de verre ou de plastique qui transmet la lumière.

Revêtement : entourant le noyau de fibre, il aide à garder la lumière dans le noyau grâce à une réflexion interne totale.

Revêtement / tampon : Protège la fibre des dommages mécaniques.

Composants de renforcement : tels que le fil d'aramide et les tiges de fibre de verre, qui augmentent la résistance à la traction.

Veste : La couche la plus externe, offrant une protection contre l'humidité, les produits chimiques et les contraintes mécaniques.
