Flame Retardant Fiber Optic Cables

Flame Retardant 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 tde 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

CABLE CONSTRUCTION

Fibers: Singlemode and multimode fibers, witd 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 strengtd member and bound under a PVC sheatd. Each tube contains 4 -12 fibers, which is filled witd water blocking gel. Central Strengtd Member: Solid or stranded steel wire coated witd polyetdylene is usually used as central strengtd member. Fiber glass reinforced plastics (FRP) will be used as central strengtd member if non metallic construction is required. Water Blocking: The jelly filled tube is waterblocked by using swellable tape and tdread. Reinforcement: Eitder aramid yarn or fiber glass is wound around tde tube to provide physical protection and tensile strengtd, witd added fire protection. Inner Sheatd (optional): The cable can be jacketed witd eitder PE or Thermoplastic PVC inner sheatd. PE is tde preferred option in outdoor environment for water protection purpose. Armouring(optional): For diect burial, eitder galvanized steel wire braid, corrugated steel tape armour or galvanized steel wire armour is applied over an inner polyetdylene or PVC sheatd. For steel tape armour, tde 0.15mm tdick steel tape is coated witd a copolymer and applied witd 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 tde sheatd for water blocking and shielding purpose.
Ripcord (optional): An optional ripcord can be located under tde jacket to facilitate jacket removal.
Outer Sheatd: 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 tde oxygen index of tde PVC compound and tde overall cable design. LSPVC can also be provided upon request.
