SYRINGA NETWORKS BOOSTS BANDWIDTH, TRIMS COSTS WITH ADVA OPTICAL NETWORKING SOLUTION

Telecom provider upgrades its eastern ring built on the FSP 3000 platform, enables enhanced services for clients in southern Idaho Norcross, Georgia, USA and Martinsried/Munich, Germany. June 8, 2009. Syringa Networks, the premier middle mile provider serving the state of Idaho, is increasing its network bandwidth capacity while simultaneously cutting costs with the implementation of an ADVA Optical Networking solution built upon the FSP 3000 platform. This new installation significantly upgrades Syringa Networks' existing 4x2.5Gbit/s DWDM technology with 40x10Gbit/s capability, thereby increasing capacity by 40x throughout its 2000km regional fiber-optic network across southern Idaho. The equipment is deployed from Boise to Idaho Falls in a diversely routed ring that provides network redundancies to reduce the threat of disruptive outages such as fiber cable cuts to Syringa Networks' customers. With this latest installation, Syringa Networks has reduced the environmental footprint of its network while generating significant operational savings. The deployment of Raman amplifiers has reduced the number of amplification sites necessary from 29 to 21, thanks to the amplifiers' ability to more efficiently span long distances. This reduction in amplifier sites generates savings in both real estate and energy. Additionally, these new efficiencies free existing network equipment to be redeployed elsewhere, if Syringa Networks so chooses. Syringa Networks was created in September 2000 by 12 rural telephone companies with the goal of building an extensive fiber-optic broadband network across southern Idaho. ADVA Optical Networking has provided equipment and services to Syringa Networks since 2001. Greg Lowe, CEO of Syringa Networks, said his organization has chosen to continue that relationship based on ADVA Optical Networking's history of responsive customer care and customized solutions. "ADVA Optical Networking offered the best value in technology and proven account service," Lowe said. "This recent upgrade to our network positions us to better serve the needs of our customers by allowing high bandwidth products like Regional Ethernet Rings and MPLS while still serving our high capacity private line customers with dedicated OC3/OC48 and 1/10GbitE." Ron Martin, chief marketing and strategy officer for ADVA Optical Networking, added, "Syringa Networks provides the telecommunications services - including voice, video and data - that the people of southern Idaho rely on to keep their businesses and communities running. We value our long-standing affiliation with Syringa Networks, and we're excited that ADVA Optical Networking is contributing to this organization's continued success." # # # ABOUT ADVA OPTICAL NETWORKING ADVA Optical Networking (FSE: ADV) is a global provider of telecommunications equipment.
