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 GR409-CORE / TIA/EIA 568B.3 / ICEA-S-83-596

VOLTAGE RATING
60V

CABLE CONSTRUCTION
Optical fibers: Singlemode and multimode tight fibers, with tight buffer coating.
Fire Barrier: The tight buffered fibers are wrapped with fire blocking fiber glass yarns.
Inner Sheath(optional): Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1
Ripcord(optional): An optional ripcord can be located under the outer sheath to facilitate jacket
removal.
Armouring(optional):
STA: Corrugated steel tape armour
SWB: Steel wire braid
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.)

Physical AND THERMAL PROPERTIES
Temperature range during operation (fixed state): -20°C - +60°C
Temperature range during installation (mobile state): 0°C - +50°C
Minimum bending radius: 10 times the outer diameter for unarmoured cables
20 times the outer diameter for armoured cables
