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.
