Fire resistant Multi Loose Tube Fiber Optic cables

Application

The multi loose tube non metallic cables are designed for outside plant, which is prone to electrical interference.

They are mainly installed inside buildings, tunnels,subways or closed areas in general, specially designed to

guarantee the signal transmission even in case of fire. The cable can also be used for direct burial for armoured

version.

CABLE CONSTRUCTION

Fibers: Singlemode and multimode fibers, with loose tube technology.

Structure: The cable consists of 5 to 36 fibers containing tubes or fillers stranded in up to 3 layers around a

central strength member and bound under a LSZH sheath. Each tube contains 4 -12 fibers, which is filled with

water blocking gel.

Central Strength Member: Solid or stranded steel wire coated with polyethylene is usually used as central

strength member. Fiber glass reinforced plastics (FRP) will be used as central strength member if non metallic

construction is required.

Fire Barrier: The jelly filled tubes containing the fibers are individually wound with fire blocking mica glass tape

and are cabled around a central strength member

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.

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.

Moisture Barrier Tape (optional): An aluminum moisture tape can be incorporated under the sheath for water

blocking and shielding purpose.

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.)
