The efficiency of high-speed Internet service depends on the excellence of its infrastructure components. An Eden Prairie, Minnesota firm is a leading manufacturer of reliable hardware for the industry, serving big name clients in over 130 countries.

ADC Telecommunications (NASDAQ: ADCT) provides infrastructure equipment used by wireline, wireless, cable, broadcast and enterprise networks. Its systems connect high-speed Internet, data, video and voice services to residential, business and mobile subscribers. The firm also provides network management software and integration services. Ciena (NASDAQ: CIEN), Morgan Stanley (NYSE: MS) and Verizon Communications (NYSE: VZ) are on the company's customer list.

The firm surprised the Street last week, when it reported fiscal Q4 EPS of 30 cents and revenues of $330 million. Analysts had been looking for 22 cents and $318.4 million. Management also guided FY08 EPS to $1.12-1.22, versus Street consensus of $1.17. Merriman Curhan Ford subsequently upgraded the shares to "buy", Friedman Billings reiterated its "outperform", and Robert W. Baird noted that the firm's conservative outlook sets the stage for further outperformance.
