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.

• Cables tested according to TIA/EIA-455 and IEC-60794-1-2. For details see Test Methods Table
• Cables ordered with HFFR jackets meet IEC-60332-1 standard
• Cables meet or exceed Telcordia (Bellcore) requirements for indoor plant cables (GR-409)
• On request cables meeting the IEC-60332-3 can be supplied
• Available in constructions meeting UL 1666 (Riser rating)

Our ADSS cables offer a rapid and economical means for deploying optical fiber cables along existing aerial rights-of-way. They are deployed by cable television operators, telephone companies, municipalities and emerging network operators, in addition to electric power utilities. The ADSS cable consists of a number of tubes/elements according to the specified number of fibers. The elements are usually fiber-containing tubes; however fillers may be used to preserve the cable
geometry.

Two to 24 color-coded fibers are loosely laid in each tube containing a water-blocking gel.The tubes are stranded around a dielectric central strength member and a water-swelling tape is helically wrapped around the cable core.

Aramid yarn strength members are helically laid to provide the required tensile performance of the cable. The outer jacket is tightly bound over the aramid yarn layer. For long span applications a double jacket design can be considered. A ripcord is located under each jacket layer to facilitate its removal.

CABLE DESCRIPTION

The cable consists of 5 to 36 elements stranded in up to 3 layers around a central strength member and bound in a jacket. The elements are usually fibre-containing tubes, however fillers are also used when needed, to preserve cable geometry. The cables can be ordered with a central member either made of a dielectric FRP, solid or stranded steel coated with polyethylene. The tubes and fibres are colour coded. Two to 24 color-coded fibres are loosely laid in each tube. Maximum fibre count is 864. Standard tube diameters are:

• 2.1 mm – up to 12 fibres/tube – LDB sub-series
• 2.5 mm – up to 24 fibres/tube – LDC sub-series
• 2.8 mm – up to 24 fibres/tube – LDD sub-series
• 3.1 mm – up to 24 fibres/tube – LDE sub-series

In addition to our All-Dry (gel-free) DRC Cables, a variety of cable water-blocking options is available: gel filling in the tubes, core and/or between jacket layers, or dry water-blocking tapes or yarns in the tubes, core and/or between jacket layers. A ripcord is located under each jacket layer to facilitate its removal.

A wide range of jacket and armouring options is available: PE, FR-LSZH (HFFR) materials, corrugated steel armouring, steel wire and steel braid armouring, fiberglass armouring, aramid yarns, anti-termite etc. A Fig-8 self-supporting design is also available for all fibre-counts.
