About Corporate Overview

ADTRAN, Inc. is a leading global provider of open, disaggregated networking and communications equipment that enable voice, data, video and internet communications across any network infrastructure. From the cloud edge to the subscriber edge, we empower communications service providers around the world to manage and scale services that connect people, places and things. Our solutions are currently in use by service providers, private enterprises, government organizations and millions of individual users worldwide.

Incorporated in 1985, we began operations in 1986 following AT&T’s divestiture of the Regional Bell Operating Companies (RBOCs). This created an opportunity for companies like us to supply network equipment to the seven RBOCs as well as the more than 1,300 independent telephone companies in the United States. From a humble beginning with only seven employees, we have grown into a global leader in telecommunications with more than 2,000 employees. Likewise, the company serves a diverse customer base that spans more than 68 countries.

With products for both carrier and enterprise markets, we are uniquely positioned to provide complete end-to-end solutions that produce the greatest network efficiency and at the lowest possible cost. Service providers depend on our equipment to connect central offices or remote terminals directly to subscriber equipment. This enables the delivery of voice, video and Internet services all while supporting business customers with a full line of business-class networking solutions.

With the demand for bandwidth increasing at phenomenal rates, we are at the forefront of the development of new technologies that will enable service providers to glean more bandwidth from their existing infrastructure as well as new virtualized technologies that will pave the way for greater network scale and efficiency, enabling new services to reach more customers faster than ever before.


We take an active role in the communities in which we do business through employee volunteer efforts and corporate sponsorships and donations. The company strives to be a good corporate citizen and promote community involvement among its employees.
