LD Series High Performance Loose Tube Fiberoptic Cables

APPLICATIONS

• Long-distance outside plant telephone, CATV as well as data communications
• Direct burial and installation in ducts either by the pulling or by the blowing  methods
• Aerial installation as the Figure-8 self supporting option
• High fiber count indoor installations 

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 fiber-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, or made of solid or stranded steel coated with polyethylene. The tubes and fibers are color coded. See Color Code Table.
Two to 16 color-coded fibers are loosely laid in each tube that is filled with a water-blocking gel. Standard tube diameters are:

• 2.1 mm - up to 12 fibers/tube - LDB sub-series;
• 2.5 mm - up to 16 fibers/tube - LDC sub-series;
• 2.8 mm - up to 16 fibers/tube - LDD sub-series.

A variety of cable water-blocking options is available: gel filling in the core and/or between jacket layers, and dry water-blocking tapes or yarns in the core and/or between jacket layers.
A wide range of jacket options is available: polyethylene, halogen-free flame-retardant material (HFFR / LS0H), corrugated anti-rodent steel armoring, fiberglass armoring, aramid yarn, and more.
A Fig-8 self-supporting cable is available in all fiber-counts.
A ripcord is located under each jacket layer to facilitate its removal.

STANDARDS

• Cables tested according to TIA/EIA-455 and IEC-60794-1-2. For details see Test Methods Table.
• Cables meet or exceed Telcordia (Bellcore) requirements for outside plant cables (GR-20) when the appropriate options are chosen
• Cables ordered with HFFR jackets meet IEC-60332-1 standard. On request cables meeting the IEC-60332-3 can be supplied.

MARKING

Cables are marked as follows
Synergy Cables  -   Fiberoptic Cable  -   Cable Code   -  RoHS  -   Length in Meters
or per customer request. Fig-8 Self-supported cables do not comply with ROHS.
