CABLE CONSTRUCTION Fibers: Singlemode and multimode fibers, with loose tube technology. Structure: Central loose tube cable contains one tube with 2-24 single or multimode fibers, which are filled with water blocking gel. Fire barrier: The jelly filled tube with up to 24 fibers is wrapped with a fire blocking mica glass tapes. Water blocking: The jelly filled tube is waterblocked by using swellable tape and thread. Reinforcement: Either aramid yarn or fiber glass is wound around the tube to provide physical protection and tensile strength, with added fire protection. Inner sheath (optional): The cable can be jacketed with either PE or thermoplastic LSZH inner sheath. PE is the preferred option in outdoor environment for water protection purpose. Moisture Barrier Tape (optional): An aluminum moisture tape can be incorporated under the sheath for water blocking and shielding purpose. Armouring(optional): For diect burial, either galvanized steel wire braid, corrugated steel tape armour or galvanized steel wire armour is applied over an inner polyethylene or LSZH sheath. For steel tape armour, the 0.15mm thick steel tape is coated with a copolymer and applied with an overlap. For steel wire braid or armour, single layer of galvanized steel wire braid or armour is applied. Ripcord (optional): An optional ripcord can be located under the jacket to facilitate jacket removal. Outer Sheath: Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1(Thermosetting LSZH compound type SW2-SW4 as per BS 7655-2.6 can be offered.)
