Fiber Optic Cable for Conduit Underground Installation by Corning Singlemode

Underground cables are pulled in conduit that is buried underground, usually 3 to 4 feet deep to reduce the likelihood of accidentally being dug up. In extremely cold climates, cables may need to be buried at greater depths where the temperatures are colder and frost penetrates to greater depths. The process usually begins with digging a trench to bury the conduit which is generally PVC plastic pipe, sometimes with pre-installed innerduct (also called duct liner) with a pulling tape to facilitate the actual cable pulling process. Directional boring can also be used to avoid digging up the surface, for example in crossing streets or sidewalks. If the conduit and cables are all-dielectric, as they usually are, a conductive marker tape should be buried above the conduit to assist in future cable location and as a warning to anyone digging in the vicinity of the cable. Conductive tape to be detectable should be no more than 300mm (12 inches) below the surface. This is Corning part number 072ZU4-T4F22D20 ALTOS 72-strand fiber optic cable with Binderless* FastAccess technology is an all-dielectric gel-free cable designed for outdoor and limited indoor use for lashed aerial and duct installations. The innovative FastAccess technology feature combined with the gel-free binderless loose tube design simplifies the removal of the cable jacket and accessing the buffer tubes. The loose tube design uses Corning's SMF-28 Ultra fiber to provide reliable transmission parameters for a variety of voice, data, video, and imaging applications. The cable is fully waterblocked using craft-friendly, water-swellable materials, which means no cleanup is required. The flexible buffer tubes are easy to route in closures, and the SZ-stranded, loose tube design isolates fibers from installation and environmental rigors while allowing easy midspan access. The all-dielectric gel-free cable construction requires no bonding or grounding, and these cables have a medium-density polyethylene jacket that is rugged, durable, and easy to handle. Corning’s patented Binderless* FastAccess® Technology refers to the combination of a Corning FastAccess Technology jacket with an innovative technology used to bind cable construction through the manufacturing process, eliminating the use of binder yarns and water-blocking tapes.
