Fire Resistant Multi Loose Tube Fiber Optic Cables,Fire Resistant Optic Fiber Cables

Fire resistant Multi Loose Tube Fiber Optic cables Application:The multi loose tube non metallic cables are designed for outside plant,Website:, 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 versionSTANDARDS:Basic design to Telcordia GR-20 / RUS 7 CFR 1755.900 (REA PE-90) / ICEA S 87-640FIRE PERFORMANCECircuit IntegrityIEC 60331-25; BS 6387 CWZ; DIN VDE 0472-814(FE180);CEI 20-36/2-1; SS229-1; NBN C 30-004 (cat.

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 usedas central strength member. Fiber glass reinforced plastics (FRP) will be used as central strengthmember if non metallic construction is required.Fire Barrier: The jelly filled tubes containing the fibers are individually wound with fire blocking micaglass tape and are cabled around a central strength memberWater 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 physicalprotection and tensile strength, with added fire protection.Inner Sheath (optional): The cable can be jacketed with either PE or Thermoplastic LSZH innersheath. PE is the preferred option in outdoor environment for water protection purpose.Armouring(optional): For diect burial, either galvanized steel wire braid, corrugated steel tapearmour 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 withan overlap. For steel wire braid or armour, single layer of galvanized steel wire braid or armour isapplied.Moisture Barrier Tape (optional): An aluminum moisture tape can be incorporated under thesheath 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 LSZHcompound type SW2-SW4 as per BS 7655-2.6 can be offered.)Physical AND THERMAL PROPERTIESTemperature range during operation (fixed state): -20°C - +60°CTemperature range during installation (mobile state): 0°C - +50°CMinimum Installation Bending Radius: 20 times the outer diameterMinimum operation Bending Radius: 10 times the outer diameter for unarmoured cables20 times the outer diameter for armoured cablesCONSTRUCTION PARAMETERSCable CodeFiberCountTubeDiameterNominal Overall DiameterApprox.WeightTension loadCrush(n°)mmmmkg/kmNN/100mmMLA-B-C×D-F-H-J-FR722.515.023040003000MLA-B-C×D-F-H-J-FR962.516.525040003000MLA-B-C×D-F-H-J-FR1442.520.528040003000Steel Wire BraidCable CodeFiberCountTubeDiameterNominal Overall DiameterApprox.WeightTension loadCrush(n°)mmmmkg/kmNN/100mmMLA-B-C×D-F-2Y(SWB)H-J-FR722.515.028030003500MLA-B-C×D-F-2Y(SWB)H-J-FR962.517.531030003500MLA-B-C×D-F-2Y(SWB)H-J-FR1442.521.535035003500Corrugated Steel Tape ArmourCable CodeFiberCountTubeDiameterNominal Overall DiameterApprox.WeightTension loadCrush(n°)mmmmkg/kmNN/100mmMLA-B-C×D-F-2Y(STA)H-J-FR722.516.529030007500MLA-B-C×D-F-2Y(STA)H-J-FR962.518.535030007500MLA-B-C×D-F-2Y(STA)H-J-FR1442.522.545035007500Steel Wire armourCable CodeFiberCountTubeDiameterNominal Overall DiameterApprox.WeightTension loadCrush(n°)mmmmkg/kmNN/100mmMLA-B-C×D-F-2Y(SWA)H-J-FR722.015.036035005000MLA-B-C×D-F-2Y(SWA)H-J-FR962.016.539040005000MLA-B-C×D-F-2Y(SWA)H-J-FR1442.018.543045005000Mechanical PropertiesMaximum Compressive Load:4000N for unarmoured cables6000N for armoured cablesRepeated Impact:4.4 N.m (J)Twist (Torsion):180×10 times, 125×ODCyclic Flexing:25 cycles for armoured cables100 cycles for unarmoured cablesCrush Resistance:220N/cm(125lb/in)Fiber ComplianceTemperature CyclingIEC60794-1-2-F2Tensile StrengthIEC60794-1-2-E1ACrushIEC60794-1-2-E3ImpactIEC60794-1-2-E4Repeated BendingIEC60794-1-2-E6TorsionIEC60794-1-2-E7KinkIEC60794-1-2-E10Cable BendIEC60794-1-2-E11Cool BendIEC60794-1-2-E11
