 Cables de Fibra óptica
Central Loose Tube Under Water Cable
Solicitud
This cable exhibits excellent tensile strength and side press retardancy, having excellent mechanical and environmental performance. Featured by its thin diameter and light weight, it is best suited for underwater condition, junction communication system and long haul communication system.
Descripción
Central loose tube cable contains one tube with 2 - 24 fibers, which is filled with water blocking gel. A water swelling tape is helically wrapped around the cable core. Either aramid yarn or fiber glass is wound around the tube to provide physical protection and tensile strength. The cable is jacketed with PE for water protection purpose. For direct burial, steel wire armour and corrugated steel tape armour are applied with an optional PE inner jacket. An optional Aluminium moisture tape can be incorporated under the jacket for water blocking and shielding purpose. An optional ripcord can be put under the jacket to facilitate jacket removal.
