Sales office to intensify focus on regional opportunities Mahwah, New Jersey, USA and Martinsried/Munich, Germany. September 25, 2007. ADVA Optical Networking today announced the opening of an office in Gurgaon, near New Delhi, India, to better serve its existing and potential customers in that country. "India's market for optical systems was worth roughly $200 million in 2004, but I expect to see this expand to nearly $500 million by 2011," commented Matt Walker, Senior Analyst with Ovum-RHK's Network Infrastructure group. "There continues to be strong build out of backbone, core and edge infrastructure in India, whose huge population and large base of multinational companies are vastly underserved by the telcos. Fast-moving, competitive service providers are installing infrastructure and leap-frogging several generations of technology to roll out the latest equipment and services across the country. Incumbent operators and utilities are also extending their networks to keep up with demand and the competition. India will remain an exciting, high-growth optical market for at least several years." Worldwide, end users continue to drive video across the network, while enterprises push growing amounts of data on a regular basis. In India, service providers are building out core infrastructure to increase teledensity in the country, driving terrestrial and mobile telephony services into remote areas and responding to demand for broadband connectivity in urban areas. Along with such rapid development comes the fundamental need for high-capacity networks to provide backhaul services for Digital Subscriber Line (DSL) and mobile services. The foundation for these high-capacity, next-generation networks is Wavelength Division Multiplexing (WDM) technology, combined with carrier-class intelligent Ethernet access technology. ADVA Optical Networking provides an innovative combination of Optical+Ethernet technologies that form the foundation for tomorrow's next-generation networks. The ADVA Fiber Service Platform delivers the flexibility, scalability and optimal solutions required by carriers facing rapid network development, like those in India. "The Indian market is expanding at an exciting pace," said Michael Donhauser, Managing Director of ADVA Optical Networking Asia-Pacific. "From carrier backbones to enterprise backbones to mobile infrastructure and access networks, the incumbents and a large number of new, alternative operators are competing hard to connect a fast-growing population demanding new services. Our new office in India allows us to be in the middle of this hot market to offer advanced, innovative solutions from a location close to the customer." ADVA Optical Networking's New Delhi office is one of 20 globally that together employ close to 1,000 professionals. The new office is located at GF#4 JMD Pacific Square, Gurgaon Haryana, India 122001. The main telephone number is +91 1244 1176 05.
