Infinera Digital Optical Network Deployed by Cox Communications for Northern Virginia Metro Network

SUNNYVALE, CA--(Marketwire - June 24, 2008) - Infinera (NASDAQ: INFN) announced today that Cox Northern Virginia has deployed an Infinera Digital Optical Network for its metropolitan network. Based on pioneering large-scale photonic integrated circuits (PICs), Infinera's Digital Optical Network enables Cox to deliver services with industry-leading speed, simplicity, and flexibility.

The advanced features of an Infinera Digital Optical Network give Cox the ability to deliver voice, video and data service in its core metro network. Infinera's Bandwidth Virtualization™ architecture enables a variety of data rates and protocols, from 155 Megabits/second up to 10 Gigabits/second (Gb/s) and 40 Gb/s, and Ethernet and SONET, to be delivered over the same optical infrastructure with little or no optical re-engineering. Interchangeable client-side optical modules enable a mix of new services to be deployed simply and cost-effectively anywhere in the network at any time. Infinera's GMPLS-powered service intelligence enables services and network resources to be configured in software. The result is a dramatic reduction in time required to implement service upgrades -- from weeks or months to just days, hours, or even minutes.

Speed, Scalability, and Reliability

The advanced features of the Infinera Digital Optical Network provide the scalability and reliability to deliver high-quality services and manage the challenges of changing or growing bandwidth demand. Infinera's unique PIC-based architecture puts 100 Gb/s of optical capacity on every line card. Infinera's new ILS2 line system will offer future scalability of up to 8 Terabits/second of capacity on an optical fiber, enough to carry more than 400,000 individual HDTV signals down a single optical fiber smaller than the width of a human hair. The Infinera system offers integrated switching and optical transport and the digital multicast capability, making it simple and cost-effective to accommodate large or shifting demands for video-on-demand and television services.

Cox's Northern Virginia metro network is linked to the company's 12,000 mile long-haul Infinera Digital Optical Network that extends from coast to coast, enabling Cox to deliver leading-edge services including voice, video and data to all of its markets.

"Consumers are demanding more services from their providers in an increasingly competitive environment. The Infinera network enables us to be fast, flexible, and highly responsive to our customers," said Cox Northern Virginia Vice President of Network Operations Darryl Ladd.

"We are very pleased to support Cox Northern Virginia with a state-of-the-art Infinera Digital Optical Network," said Infinera CEO Jagdeep Singh. "Infinera is focused on innovation that enables faster, more flexible optical networks that can support the unique demands of today's businesses and consumers."
