ADVA's 100G Metro solution leverages 4x28G direct detection technology. Corning's LEAF fiber requires dispersion compensation modules (DCMs) be used only in the terminals at the ends of the link.
“In the metro environment, enterprises and service providers have been cautious about deploying 100G technology,” said Barry Linchuck, division vice president and director, Worldwide Marketing, Optical Fiber, Corning Incorporated. “They need a 100G solution at the right cost point. With this demonstration, we've clearly shown the tremendous opportunities possible through the complimentary features of ADVA Optical Networking's 100G Metro solution and Corning LEAF fiber.”
