Flame Retardant Central Loose Tube Fiber Optic cables

Application

These cables are characterized by light weight and small diameter, suitable for both aerial and duct
installation. 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.

Standards

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

Note: Asterisk ** denotes that the standard compliance is optional, depending on the oxygen index of the PVC compound and the cable design.

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 PVC 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 PVC 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 PVC compound. UV resistance, hydrocarbon resistance, oil resistance,
anti rodent and anti termite properties can be offered as option. Compliance to fire performance
standard (IEC 60332-1, IEC 60332-3, UL 1581, UL 1666 etc) depends on the oxygen index of the
PVC compound and the overall cable design. LSPVC can also be provided upon request.
