Tellabs announced Multiple Dwelling Unit (MDU) support for its Tellabs 1600 Series Optical Network Terminal (ONT) product line. This capability enables service providers to leverage existing wiring in multi-dwelling buildings, such as apartment complexes or university residence halls, in Fiber-to-the-Premises (FTTP) deployments.

Tellabs' MDU portfolio can be deployed using very-high-data-rate digital subscriber line (VDSL) over existing copper wiring, or Ethernet cabling in newer construction, while leveraging coaxial cable for video as required. Previously, coping with a diverse blend of infrastructure and negotiating permission from property owners to install fiber in individual units were significant obstacles for broadband service delivery to these locations.

According to industry estimates, MDUs account for up to 25% of the addressable market for residential and small business broadband services in large cities. Market research firm In-Stat predicts that U.S. MDU in-building broadband subscribers will double from 5 million in 2004 to 10 million in 2009. Tellabs is the market leader in supplying fiber-based access solutions in North America, with more than 1 million lines in service.

"This product further demonstrates Tellabs' leadership in fiber-based access solutions and enables our customers to extend the reach of FTTP-based services," said Carl DeWilde, executive vice president, broadband products, for Tellabs. "Tellabs' continued technology enhancements exemplify a commitment to advancing our customers' networks to better meet evolving end- user needs."

The new Tellabs ONTs are Session Initiation Protocol (SIP) ready, enabling easy migration to support Voice over Internet Protocol (VoIP) when the service provider is ready to implement the transition. Video services can be delivered via radio frequency video overlay or Internet Protocol Television (IPTV). Tellabs also provides optional element management systems that remotely manage operational, administrative, maintenance and provisioning functions to further reduce expenses.

General availability of the Tellabs 621 MDU ONT and the Tellabs 625 MDU ONT is scheduled for first-quarter 2006. The Tellabs 1600 series is a part of the Tellabs DynamicHome solution, an end-to-end solution that delivers reliable video, voice and data services.
