Aegis Lightwave intros tunable receiver for wavelength-agile PON FTTH

MARCH 19, 2010 -- Aegis Lightwave has announced a new wavelength-tunable receiver for wavelength-agile PON will be demonstrated at OFC/NFOEC 2010 in Booth 419. Results of a laboratory trial demonstrating coexistence of wavelength-agile PON with existing GPON will also be presented.

MARCH 19, 2010 -- Aegis Lightwave has announced a new wavelength-tunable receiver for wavelength-agile PON will be demonstrated at OFC/NFOEC 2010 in Booth 419. Results of a laboratory trial demonstrating coexistence of wavelength-agile PON with existing GPON will also be presented.

Aegis Lightwave says a wavelength-agile PON system has four times the downstream bandwidth compared to currently deployed GPON or GEPON systems, which operate at a downstream bit rate of 2.5 Gbps. The tunable receiver technology is designed to relieve the downstream bandwidth bottlenecks created by growing consumer demand for video services on home entertainment systems and mobile devices. Wavelength-agile ONT systems deployed in subscribers’ homes or at wireless cell sites will eliminate latencies at the edges of the communications network and significantly improve user experience on the Internet, the company asserts.

The wavelength-tunable receivers will enable wavelength-agile ONT systems to receive four different laser wavelengths, each transmitting to the GPON standard. Service providers can add these laser wavelengths incrementally, thus lowering their initial capital expenditures, Aegis says. Service providers can also dedicate wavelengths to high bandwidth subscribers. Each wavelength operates over the existing PON infrastructure at a bit rate of 2.5 Gbps for a total aggregate downstream bandwidth of 10 Gbps.

“Optical re-configurability and dense wavelength division multiplexing are ubiquitous features of today’s core optical networks,” said Jeffrey Farmer, president and CEO, Aegis Lightwave. “Our tunable filters extend such wavelength-selective applications to the edge of the passive optical network to allow service providers to multiply their downstream bandwidth at a very low incremental cost.”
