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 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.)
