Headquartered in Hauppauge, New York, Telebyte, Inc. is the recognized leader in G.fast test equipment. The high-tech enterprise sells an extensive selection of physical-layer test equipment used by major companies around the world for ID-337 certification preparation, as a common platform for vendor trials, for next-gen research and development, interoperability and more.

Products include crosstalk emulators, local loop simulators, noise generators, digital analyzers, test automation switches, cable farm automation switches and more. While they continue to offer their well-established solutions for VDSL2, ADSL2 and the lower bandwidth technologies, the primary focus for new product development is on VDSL2 vectoring and G.fast.

Telebyte is an active participant in meetings of the Broadband Forum that shape the future of DSL, as well as a member of the UNH-IOL DSL Consortium.

Since 1983, Telebyte has been dedicated to leading the industry in product quality and customer service, deploying thousands of Telebyte products around the world through its network of domestic and international distributors.
