COFOUR-f® | Outside Plant Copper Cable (Exchange Cable) | Copper Shield | Single Jacket | Filled–Gel

Conductors: Solid annealed copper in 19, 22 and 24 AWG.

Insulation: Conductors are insulated with solid polyolefin, 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®-F is available with a screen for use with T-Carrier systems. CoFOUR®-F + M is available with mechanical protection.
