OFS DryBlock® Armored Loose Tube Cable

Product Description

The Lightera DryBlock® Armored Loose Tube Cable offers an exceptionally rugged and highly reliable cabling solution for a wide range of demanding outside plant (OSP) applications, including direct buried in harsh environments. A layer of corrugated steel armor teams with two robust polyethylene (PE) jackets to deliver the muscle and rodent resistance needed for the most rigorous OSP use, in a cable that remains lightweight and easy to install.

To construct the cable, one to 12 optical fibers are placed within color-coded, gel-filled buffer tubes to protect the fibers from external mechanical and environmental forces and simplify fiber management. The buffer tubes are then stranded around a dielectric central member using the reverse oscillating lay (ROL) stranding method. Unlike other methods, ROL stranding enables quick and easy mid-span entry. DryBlock water-blocking material and dielectric strength elements are then applied to the cable core. Finally, a single layer of electrolytically chrome-coated steel (ECCS) armor is encased between two layers of hardy PE sheathing to complete the cable construction.

Why the DryBlock Armored Cable?

The DryBlock Armored Loose Tube Cable offers an exceedingly durable, dependable solution for the most difficult OSP applications. Dual PE jackets and a layer of ECCS armor provide the outstanding compressive strength and rodent resistance needed to conquer highly challenging direct buried and lashed aerial installations.

By featuring DryBlock water-blocking technology, this armored cable delivers outstanding protection from water penetration while also saving time on cable preparation and splicing. Cables that use DryBlock material require the use of virtually no cleaning solvents during installation, helping to increase efficiency and save on cable preparation and installation time. The craft-friendly, jelly-free core of a DryBlock cable also weighs less and is easier to handle.

The DryBlock Armored Loose Tube Cable is an excellent choice for demanding OSP installations including direct burials, duct, and lashed aerial, along with applications requiring added compressive strength and/or extra rodent resistance.
