RESEARCH TRIANGLE PARK, N.C. -- Sumitomo Electric Lightwave today announced the introduction of the industry's first bend-insensitive fiber drop cables for fiber-to-the-premises (FTTP) and fiber-to-the home(FTTH) applications. By integrating Sumitomo's PureAccess® bend-insensitive optical fibers to its entire drop cable product line, Sumitomo Electric Lightwave has increased the flexibility and overall utility of drop cables leading directly to the subscribers' premises.

Having combined low bending loss with its easy entry cable designs, Sumitomo drop cables facilitate easier fiber handling for tight bends at the edges of walls and tighter fiber coiling within entry ports and network interface devices located at the premise, multiple dwelling unit (MDU), or home. The PureAccess drop cables feature fibers with minimum bend radiuses of 15 mm, a 50% decrease in bend sensitivity of conventional single-mode fiber, which allows for even greater fiber density with low bending loss for component and tight-access wiring necessary in FTTP applications. When wrapped around a 30mm diameter mandrel, PureAccess fiber exhibits no additional attenuation loss, thereby preserving signal strength. The innovation also addresses the industry's need for component miniaturization and speeds the development of smaller and less intrusive devices, such as closures and entry boxes, at the subscriber's location.

"Our focus is to provide our customers with a competitive advantage in servicing their subscribers with robust solutions that assure the highest reliability," comments Gary Bishop, Sumitomo Electric Lightwave's director of product management. "Under tight bending conditions, the PureAccess fiber will not suffer the stress and signal degradation as would conventional fiber, making the PureAccess drop cables an outstanding choice for ensuring the highest quality of service."
