FEBRUARY 22, 2008 -- Corning Inc. (search for Corning) and Infinera (search for Infinera) say they will demonstrate how optimal integration of their optical fiber and transmission system products can enable simplified and cost-effective long-haul network designs with two demonstrations at OFC/NFOEC Feb. 26-28, 2008 in San Diego, Calif.
The first demonstration is designed to show how long, unamplified optical reach enables carriers to reduce amplification requirements and the expenses associated with building and maintaining amplifier huts. In the demonstration, Infinera's Digital Optical Networks technology will transmit and receive data over 320 km of Corning SMF-28 ULL fiber to demonstrate extended network reach that can eliminate two or three amplification sites traditionally required in a network with 80- or 100-km spans. The long-reach capability results from the combined benefits of Infinera's Raman amplification and the ultra-low attenuation of SMF-28 ULL fiber.
Corning and Infinera say they will also demonstrate the benefits to carriers and service providers of using lower-cost dispersion compensation equipment. The Infinera DTN will transmit over six 100-km spans of Corning LEAF fiber with no in-line dispersion compensation. Link dispersion compensation is achieved through a single dispersion compensation module and electronic dispersion compensation in the receiver terminal on the Infinera line card. Due to the optimized dispersion of LEAF fiber, in-line dispersion compensation is not required, the companies assert.
