ADVA, Corning Demo 100G Direct Detection across 600 Kilometer Optical Fiber

ADVA Optical Networking and Corning conducted the joint demonstration at ADVA’s Meiningen campus in Germany using the ADVA (News - Alert) FSP 3000 solution with inline amplification and Corning LEAFfiber.
This demonstration highlights the fact that direct-detection 100G technology can be used optimally outside a metro environment. The suitability of the solution as a genuine 100G solution for regional networks has been verified as well.
Stephan Rettenberger, vice president of marketing for ADVA Optical Networking (News - Alert), said, “It was built as a direct response to our customers’ demands for an efficient 100G solution designed specifically for the needs of the metro environment. Since its launch, our customers’ feedback has been clear: take the 100G Metro farther.”
With Corning’s optical fiber technology, ADVA has been successfully able to prove that it is possible to transport data across distances of over 600km. Service providers and enterprises can benefit a lot from 100G deployments in the metro environment and eliminate problems of power consumption and footprint of coherent technology, said officials.
Space and cost advantages are ensured by ADVA Optical Networking’s 100G Metro solution built on 4x28G direct detection technology. This solution, along with Corning LEAF fiber, delivers low-loss, non-zero dispersion shifted fiber that serves regional networks as well.
LEAF fiber features optimum dispersion properties and hence needs dispersion compensation modules (DCMs) only in the terminals at the ends of the link. Here, usage of DCMs and inline amplifiers is more economical compared to standard single-mode fiber.
“In the metro environment, enterprises and service providers have been cautious about deploying 100G technology. They need a 100G solution at the right cost point,” said Barry Linchuck, division vice president and director of Worldwide Marketing, Optical Fiber, Corning Incorporated. “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.”
Recently, ADVA unveiled Reconfigurable Optical Add Drop Multiplexers (ROADM) to offer the required flexibility for Optical+Ethernet networks, which are much more dynamic than their predecessors. Replicating the operational simplicity and flexibility of SONET/SDH networks at the wavelength level, they enable users to access any wavelength at any node at any time.
