TLD-LD-F

進口Teldor LD系列多套管or束管型鬆式室內外光纖纜線
(依照中華電信標準分為多套管or束管PJF類)
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.

MECHANICAL PROPERTIES
Typical properties are given next page. Actual properties depend on the cable construction.

OPTICAL PROPERTIES
See the Optical Properties Table.

MATERIALS
See information about the materials used in the Teldor Fiberoptic Cables.

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
Teldor - Fiberoptic Cable - Cable Code - RoHS - Length in Meters
or per customer request.
Fig-8 Self-supported cables do not comply with ROHS.

CABLE DIMENSIONS AND WEIGHTS
See list of most frequently ordered cables next page.

ORDERING
You can find the desired cable in the cable list next page or compose your own cable from the Cable Code Definition
and Selection Guide.
Standard cable lengths vary with cable diameter. Other constructions, color codes and materials may be available. Please contact the Teldor Marketing Department.
