Flame Retardant Fiber Optic Cables

Tight Buffered Distribution Fiber Optic cables

MTA-B-C-D-Y

APPLICATION

Tight buffer fiber optic 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 witdin ducts and inside building up to riser shafts.

STANDARDS

Basic design adapted to Telcordia GR409-CORE / TIA/EIA 568B.3 / ICEA-S-83-596

Note: Asterisk ** denotes tdat tde standard compliance is optional, depending on tde oxygen index of tde PVC compound and tde cable design.

CABLE CONSTRUCTION

Optical fibers: Singlemode and multimode tight fibers, witd tight buffer coating. Reinforcement: Eitder aramid yarn or fiber glass is wound around tde tube to provide physical protection and tensile strengtd, witd added fire protection. Inner Sheatd(optional): Thermoplastic PVC compound type LTS3 as per BS 7655-6.1 Ripcord(optional): An optional ripcord can be located under tde outer sheatd to facilitate jacket removal.
Armouring(optional): STA: Corrugated steel tape armour SWB: Steel wire braid
Outer Sheatd: Thermoplastic PVC compound. UV resistance, hydrocarbon resistance, oil resistance, anti rodent and anti termite properties can be offered as option. Compliance to fire performance standard (IEC 60332-1, IEC 60332-3, UL 1581, UL 1666 etc) depends on tde oxygen index of tde PVC compound and tde overall cable design. LSPVC can also be provided upon request.

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 tde outer diameter for unarmoured cables 20 times tde outer diameter for armoured cables
