About PairGain Technologies, Inc.

PairGain stands as the dominant supplier in the HDSL market, with over 80 percent market share. PairGain HDSL products allow telcos and corporate end users to provision advanced digital services at lower costs and in less time than with traditional repeatered T1 of fiber optic deployment. The company introduced its SPAROW chip in 1990, and since, it has become the engine of HDSL technology.

PairGain has become synonymous with the term CopperOptics, and essentially, it has come to define our business: delivering high-speed, fiber optic-quality digital transmission over `the last mile' of ordinary copper wire, allowing both public and private telecommunications providers to seamlessly link networks and end users.
