Features Lightera application-specific fibers, including AllWave® ZWP and AllWave+ Single-Mode along with Multimode Fibers

Product Description

The High-Density Loose Fiber Cable offers increased carrying capacity in a non-ribbonized, loose fiber cable construction. With this design, a group of 12 optical fibers is wrapped with color-coded yarn to form each fiber bundle. Next, two fiber bundles are placed within each color-coded, gel-filled buffer tube to protect the fibers from external forces. DryBlock® water-blocking material is then applied to the cable core to provide water penetration resistance. Finally, dielectric strength elements are added for extra tensile strength.

Why the High-density Loose Fiber Cable?

The High-Density Loose Fiber Cable maximizes fiber density, offering an excellent solution for service providers who need increased carrying capacity and prefer a non-ribbon cable design. With its 1,000 pound (4450 N) rated pulling tension, this cable offers outstanding durability and reliability for a wide range of outside plant installations, including long pulls, without fiber strain.

The Reverse Oscillating Lay (ROL)-stranded, dual-layer cable core and ripcord offer fast and easy mid-span access for cable splicing and handling. DryBlock water-blocking technology makes cable preparation cleaner and easier, helping you save on time and money.
