ALFOUR-8FS®| Outside Plant Copper Cable (Exchange Cable) | Aluminum Shield | Single Jacket | Filled Foam Skin | Fig-8

Conductors: Solid annealed bare copper in 22 and 24 AWG.

Insulation: Conductors are dual insulated with an inner layer of foam, 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 and 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 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.

Support Member: A ¼ inch, 7-strand Extra High Strength (EHS) galvanized steel messenger serves as the support member and is an integral part of the sheath. The messenger is flooded to 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 including the manufacturer’s identification, pair count, AWG and product identification appears at 2-foot intervals. Sequential length markings appear at alternate 2 foot.
