Alcatel sells fiber access system to SBC

Alcatel SA has won a contract for a fiber access network system from SBC Communications Inc., the Paris equipment manufacturer said Monday in a statement.

SBC has agreed to buy, for an undisclosed amount, Alcatel's 7340 fiber-the-user (FTTU) system to provide voice, data and video services, including emerging high-speed services such as high-definition TV (HDTV), over an all optical network to consumers and small and medium-sized businesses (SMBs). The San Antonio company will initially deploy the technology in a project in San Francisco.

Alcatel's FTTU technology provides broadband data access up to 20M bps (bits per second) per subscriber.

New residential and commercial areas, where communications cables are being laid, are a prime market for FTTU technology, according to Alcatel.

The company's FTTU system uses a single fiber to connect OLT (optical line terminal) equipment in the central office to ONT (optical network terminal) devices located at the subscriber location.

Each fiber from the central office carriers one PON (passive optical network) and can be shared by up to 32 subscribers using optical splitters, thus effectively reducing the cost of the fiber supporting each subscriber.

Alcatel and SBC are collaborating on defining an architecture that supports current DSL (Digital Subscriber Line) service and makes way for FTTU technology, Alcatel said.
