MIC® Unitized Tight-Buffered, Interlocking
Armored Cable, Riser 72 F, Single-mode (OS2)

072E81 Unitized Tight Buffered Interlocking Armored Cable

Part Number: 072E81-T3131-A1
Corning MIC® interlocking armored riser cables are designed for use in intrabuilding backbone and horizontal installations.
They use individually jacketed 900 µm buffered fibers enablingeasy, consistent stripping and facilitating termination. The fibers are grouped into 6-, 12-, or 24-fiber jacketed subunits and surrounded by a dielectric central member. The core is protected by a flexible, spirally wrapped, aluminum interlocking armor that offers easy, one-step installation and up to six times the crush protection of non-interlocking armored cables. With a flame-retardant outer jacket, this cable is particularly useful for heavy traffic or more challenging mechanical exposure conditions and applications requiring extra rugged cables. This cable is available in 12 different jacket colors – blue, orange, green, brown, slate, white, red, black, yellow, violet, rose and aqua. The colored jacket allows for easy visual identification of the cables. The standard jacket color will be determined by the dominant fiber type in the cable and will use the standard part numbers shown here. Contact Customer Care at 1-800-743-2675 to order other color options.
