Fiber Optic for Indoor or Outdoor Use

Adventum, from Berk-Tek, is a loose-tube, plenum-rated fiber optic cable that can be run from the outdoors directly into a plenum environment. A product that can be used in virtually any indoor and outdoor application, these cables require no transition point and are especially advantageous for campus LANs.

The cable has been engineered without any gel-type filling compounds in the cable core or buffer tube. However, Adventum cable is fully water-blocked because it features a dry compound water-blocking scheme inside and outside of the buffer tube. This compound, along with state-of-the-art jacketing material, allows the cable to be plenum-rated. System designers and installers can place Adventum cable anywhere in a network, foregoing the building entry points required with traditional non-rated, loose tube fiber optic cable. Also, without bulky tight buffered fiber coatings, these fiber cables are up to 35% smaller and yield tighter bend radii. As a result, installation in crowded conduits is easier and less labor-intensive. Berk-Tek, New Holland, PA, (800) 237-5835,
