Abstract

En por lo menos algunas modalidades, un cable submarino descrito incluye uno o más conductos de fibra óptica inundables cada uno teniendo por lo menos una fibra óptica fuertemente protegida para transportar señales ópticas; cada fibra óptica fuertemente protegida puede tener una longitud relativamente limitada; el cable submarino adicionalmente puede incluir múltiples elementos de fuerza enrollados contra-helicoidalmente alrededor o junto con uno o más conductos de fibra óptica inundables; también o alternativamente puede incluirse por lo menos un conducto de fibra óptica sellado herméticamente que tiene por lo menos una fibra óptica protegida empalmada a una de las fibras ópticas fuertemente protegidas; por lo menos algunas implementaciones empalman cada una de las fibras óptica fuertemente protegidas a fibras protegidas correspondientes para las comunicaciones de larga distancia; la inundación de los conductos inundables puede proveerse vía conectores en los extremos de cable submarino, vía ubicaciones separadas donde se fijan los sensores, y/o vía respiraderos en la pared del conducto; Algunas modalidades del método despliegan los diseños de cable submarino descritos en un cuerpo de agua, colocando el interior de por lo menos un conducto de fibra óptica inundable en comunicación de fluido con el cuerpo de agua mientras soporta uso extendido para señales de comunicación, particularmente en agua profunda donde las temperaturas son relativamente bajas; debido a que los conductos inundables tienen interiores con presión igualada éstos pueden crearse de plástico y otros materiales que facilitan el proceso de fijar los sensores a los cables submarinos.
