Arvig Communication Systems Selects ADC RealFlex Products For FTTH Deployments In Rural Minnesota.

RealFlex Drop Cables Designed to Decrease FTTH Install Time/Increase System Reliability

MINNEAPOLIS -- ADC (NASDAQ: ADCT) (www.adc.com) today announced that Arvig Communication Systems (ACS), based in Perham, Minn. has selected its RealFlex[TM] reduced bend radius fiber (RBRF) drop cable solutions for fiber-to-the-home (FTTH) deployments in northwestern Minnesota communities. RealFlex drop cables are designed to provide for quick and easy deployments with increased reliability which allow for fast service turn-up, improved network reach and lower overall network operating and maintenance costs.

ACS selected ADC's RealFlex drop cables for its FTTH deployments because of the products' improved bend radius performance and rugged 3mm cable construction that provide the flexibility and durability to withstand the most demanding applications. They are available in indoor/outdoor, riser and plenum cable types for use in residential, business or multiple dwelling unit structures. For residential applications, RealFlex cable is used with an optical network terminal (ONT) that is installed on the side of the house, bringing the final connection to the residence. Use of this cable can save minutes per installation, which results in significant deployment savings.

"We wanted to improve the reliability and service delivery time for our customers," said Andy Klinnert, director of Network Operations for ACS. "The flexibility and ease-of-use of the RealFlex drop cables enables quicker, cleaner installations. Based on our technicians' experience, we believe the RealFlex solution is the best available for our residential applications."

RealFlex drop cables allow for a bend radius as small as 7.5 mm without changing attenuation characteristics of the cable, and they provide improved insertion loss performance for the many 90-degree bend locations found in building environments.

"ADC is a leading provider of FTTH solutions that help independent carriers meet the growing demand for broadband services in today's digital world," said Jaxon Lang, vice president of Global Connectivity Solutions, Americas for ADC. "The long term reliability and reduced installation cost benefits of our RealFlex solutions are key reasons why operators continue to select ADC's FTTX products with Reduced Bend Radius Fiber (RBRF), which have been available since November 2006."

Graybar, a leading distributor of electrical and communications products and related supply chain management and logistics services, is a key provider of ADC's entire line of FTTX infrastructure solutions. The company is supporting ACS' FTTH initiatives by providing inventory of the RealFlex products.

"ADC is a high-quality, value-added supplier and the RealFlex drop cables are a good example of how the company strives to provide the solutions that meet our customers' needs," said Bryan Hughes, Graybar branch manager for service providers in the Central Region. "We are stocking this product in the region and working with the various sales teams to ensure that these products are readily available to customers."
