Agere Systems, once known as Lucent Technologies' Microelectronics Group, released a line of full-duplex, single-fiber optical transceivers that break the "last-mile bottleneck," the company reports today. The products allow a more cost-effective delivery of analog and digital video, Internet and voice traffic to homes, businesses or curbside distribution point, Agere reports.

The two- and three-port bi-directional transceivers — called diplexers and triplexers — can receive entertainment video, and transmit and receive voice and Internet data services over a single optical fiber. The transceivers let original equipment manufacturers create systems to help service providers reduce expenses while unifying separate broadcast video, data and voice access service on one fiber.

The diplexer enables full-duplex, bi-directional data and voice transport along a single fiber.

The triplexers build on the functionality of the diplexer and integrate several video receiver options and high-bandwidth data capabilities. The 1-gig video receiver option can support all cable TV and HDTV broadcast requirements, whereas the 2-gig receiver option can support direct broadcast satellite (DBS), as well. Triplexer versions support bi-directional data rates from OC-3 to OC-24 for telephony and Internet access.

Thus far, customers include WINfirst of Denver, Colo., which signed a five-year, $800 million agreement with Lucent Technologies for equipment — including a version of Agere's diplexer — software and services to build a fiber-to-the-home residential network. WINfirst will deploy a single optical link that will allow the capacity to simultaneously download a full-length movie, view a sporting event from a Web site, stream a digital home video to a relative over the Internet, and hold multiple phone calls, Agere reports.
