Flame Retardant Optic Fiber Cables 

Flame Retardant Tight Buffered Distribution Fiber Optic cables

MTA-B-C-D-H

 

 

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.

Reinforcement: Either aramid yarn or fiber glass is wound around the tube to provide physical protection and tensile strength, with added fire protection.

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
