Fire Resistant Tight Buffered Distribution Fiber Optic cables

MTA-B-C-D-H-FR

28 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 remove

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
