Product Description

The Lightera DryBlock® Single Jacket Loose Tube Cable is a classic outside plant (OSP) cabling solution. This small diameter, lightweight cable offers the flexibility needed for duct and lashed aerial applications along with the durability critical for OSP use.

To construct the DryBlock Single Jacket 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. 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 applied to the cable core. Finally, a durable outer polyethylene (PE) jacket is added to complete the cable construction.

Why the DryBlock Single Jacket Cable?

The DryBlock Single Jacket Loose Tube Cable combines ready flexibility with the rugged durability and reliability needed for outdoor applications. The result is a time-proven OSP cabling solution that is easy to handle and install, yet robust enough for the rigors of the outside environment.

The small outer diameter of the DryBlock Single Jacket Cable makes handling easier, and ROL stranding of the buffer tubes allows fast mid-span entry. This cable also incorporates DryBlock water-blocking technology for a more craft-friendly, jelly-free cable core that is lighter in weight and easier to handle, saving on cable preparation and installation time.

The DryBlock Single Jacket Loose Tube Cable is an excellent choice for lashed aerial, duct, and general OSP applications.
