Short and medium distance, indoor and protected environments.
As a riser, or general purpose cable.
Interconnection of distribution boxes, of the distribution boxes and customer equipment, and between floors.
The cable contains 4 to 288 fibers individually buffered to 0.9 mm in a tight or semi-tight construction and coded.
The cable structure depends on the number of fibers:
In the 4-to-24-fiber cables (MTA series), the individual fibers are stranded and protected by aramid yarns and a PVC or HFFR jacket.
When more than 24 fibers are required sub-units are employed which are laid helically along the cable axis. Each sub-unit contains 4 to 12 fibers, aramid yarns and a PVC or halogen-free flameretardant sheath. The sub-units are then stranded around a central element made either of additional sub-units or a central filler.
- MTA – up to 24 fibers without sub-units
- MTB – 26-96 fibers in 4 fiber sub-units
- MTC – 98-144 fibers in 6 fiber sub-units
- MTD – 146-192 fibers in 8 fiber sub-units
- MTE – 194-288 fibers in 12 fiber sub-units
A wide range of jacket and armoring options is available: PVC, HFFR, corrugated steel , fiberglass,
aramid yarn, and more. The steel armored option is available in conjunction with a PE or HFFR
jacket. A ripcord is located under the jacket to facilitate removal.
