Flame Retardant Tight Buffered Distribution Fiber Optic Cables
MTA-B-C-D-Y
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.

Note: Asterisk ** denotes that the standard compliance is optional, depending on the oxygen index of the PVC compound and the cable design.
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 PVC 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 |
| Outer Sheath | 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 the oxygen index of the PVC compound and the overall cable design. LSPVC can also be provided upon request |
