COFOUR ®-FS | Outside Plant Copper Cable (Exchange Cable) | Copper Shield | Single Jacket | Filled Foam Skin
Pair Count 6 – 2400P
COSFOUR-F® (Telecom Copper Cables | Copper Shield | Filled Foam Skin )
Conductors: Solid annealed copper in 19, 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 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 5-mil copper 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: CoFOUR®-FS is available with an internal screen for use with T-Carrier systems. CoFOUR®-FS+M is also available with mechanical protection.
