Fiber Optic Cables  

Fiber Optic Cables

Loose under water cable


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.


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.
