Fire Resistant Tight Buffered Distribution Fiber Optic cables

MTA-B-C-D-H-FR

Fire Resistant Tight Buffered Distribution 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.

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
