Description
 |
Conductors: Solid annealed copper in 19, 22, 24 and 26 AWG. |
|
|
Insulation:
Conductors are dual insulated with an inner layer of
foamed, natural polyolefin covered by an outer layer of solid, colored
polyolefin. The conductor insulation is color coded in accordance with
industry standards. |
|
|
Twisted Pairs:
Individual conductors are twisted into pairs with
varying lay lengths to minimize crosstalk and specific color
combinations to provide pair identification. |
|
|
Core Assembly:
Cables of 25 pairs or less are assembled into a cylindrical core. Cables
larger than 25 pairs are assembled into units, which are then used to
assemble the core. Units are individually identifiable by color coded
unit binders. |
|
|
Filling
Compound:
The core assembly is filled with an 80° C ETPR or
PIB Base Jelly compound, completely filling the interstices between the pairs and under
the core wrap. |
|
|
Core Wrap: A
non-hygroscopic, dielectric tape is applied over the core assembly to
provide protection for the core.
|
|
|
Shielding:
A corrugated, copolymer coated, 8-mil aluminum tape is
applied longitudinally with an overlap. The shield interfaces are
flooded with an adhesive compound to provide a moisture barrier and
inhibit corrosion. |
|
|
Jacket:
A black, linear low-density polyethylene jacket is
applied overall. The jacket provides a tough protective covering
designed to withstand exposure to direct sunlight, atmospheric
temperature changes and stresses expected in standard installations. |
|
|
Jacket
Markings:
Information such as manufacturer's
identification, pair count, AWG, product identification and a telephone
handset is printed at 2 ft. intervals on the cable jacket. Sequential
footage markings are printed at alternate 2 ft. intervals. |
|
|
Optional Designs:
ALFOUR®-FS cables are also available with an
internal screen for use with T-Carrier systems. ALFOUR®-FS
cables are also available with mechanical protection.

|
Applications
4SProducts ALFOUR®-FS cables are designed for
direct burial or duct applications where protection from
moisture is required. ALFOUR®-FS cables may be used
aerially, but must be attached to a support strand
(messenger). ALFOUR®-FS cables, in 19, 22, 24 and 26 AWG,
are capable of meeting the electrical requirements of 100
ohms, Category 3, Backbone UTP Cables as specified in TIA/EIA-568-A.
