Firetox Flame Retardant Cables 

Flame Retardant Fiber Optic Cables

Flame Retardant Central Loose Tube Fiber Optic cables

Application

This cables are used for interconnection of distribution boxes and end devices, where continued functionality is

required during a fire situation. The cables are very suitable for various indoor and outdoor applications,

including routing between buildings within ducts and inside building up to riser shafts.

Standards

Basic design to Telcordia GR-20 / RUS 7 CFR 1755.900 (REA PE-90) / ICEA S 87-640

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.

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

oated 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.)
