ASFOUR-2-8 ® | Outside Plant Copper Cable–Exchange Cable | Aluminum Steel Shield | Dual Jacket | Air-Core | Fig-8
Pair Count 6 – 400P
ASFOUR® – 2-8 (Telecom Copper Cables | Aluminum Steel Shield | Air-Core | Fig-8)
Conductors: Solid annealed copper in 19, 22, 24 and 26 AWG.
Insulation: Conductors are insulated with a solid polyolefin. The conductor insulation is color-coded in accordance with industry standard.
Twisted Pair: 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.
Core Wrap: A non-hygroscopic, dielectric tape is applied over the core assembly to provide protection for the core.
Shielding: The dual shielding system consists of two metal tapes. Inner: A corrugated, copolymer coated, 8-mil aluminum tape is applied directly over the core wrap. The aluminum tape does not butt or overlap at any point along the length of the cable. Outer: A corrugated, copolymer coated, 6-mil steel tape is applied directly over the aluminum and overlaps. The shield interfaces are flooded with an adhesive compound to provide a moisture barrier and inhibit corrosion.
Support Member: A 1/4 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.
Outer 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.
Inner Jacket: A black polyethylene jacket.
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: AsFOUR®-2-8 is available with an internal screen for use with T-Carrier systems.
