Increasing network efficiency

“The bandwidth demand in the core of our network is increasing at an accelerating pace,” said Joachim Bellinghoven, chief operating officer at Versatel. ADVA AF Optical Networking – Germany Fax : +49 089 8906 65699

capacity and efficiency problems,” stated Eve Griliches, managing partner at ACG Research. “Instead, service providers are asking for an agile and scalable approach with fewer sites, which will enable operators to architect networks with intelligence to increase their profitability in this increasingly competitive market. ADVA Optical Networking is addressing all of these issues.”

ADVA Optical Networking has added a coherent express layer to its flagship FSP 3000 platform. been optimised for 100Gbit/s transmission speed and enables service providers to use optical network resources flexibly and on-demand. Close interworking with the IP/MPLS layer allows a massive increase in network scalability and efficiency. The feature set represents a new generation of agile optical core networks and includes the following three critical elements: • Optical layer fully optimised for 100Gbit/s coherent transmission technology – Besides the obvious benefit of increasing the capacity per wavelength, the true power of the technology lies in the extra link budget gained with coherent detection. To benefit from the extra link budget, the 100Gbit/s capabilities are complemented by cost-effective, compact and per- formance-optimised amplification schemes, all fully integrated into the control plane. The new 100Gbit/s “pipes” are not only bigger, but smarter as well. • Latest ROADM technology – ADVA Optical Networking’s Reconfigurable Optical Add/Drop Multiplexer (ROADM) solution is based on modular building blocks that support colourless, directionless, contentionless and gridless configurations. Customers can opt to deliver any transport service on any port, over any wavelength, to any direction in a network. Integrated amplification provides lowest nodal loss and highest transmission performance. • End-to-end service and bandwidth management – To make full use of 100Gbit/s and ROADM technologies, ADVA Optical Networking has fully integrated them with a powerful control plane. The control plane acts as the messaging layer for ADVA Optical Networking’s Service Manager and allows providers to provision a service from end to end in a network, removing stress from the IP/MPLS layer. “Today’s present solution – simply adding more bandwidth – does not sufficiently solve the underlying The new technology has
