ADC Telecommunications (originally Audio Development Company ) was a telecommunications company from the United States .
The company's headquarters were in Eden Prairie , Minnesota , southwest of Minneapolis ; it employed around 8,200 people.
Company history
In 1935, Ralph Allison founded ADC Telecommunications when his first product was an audiometer , a device that measures human hearing. In 1937 the engineer Walt Lehnert joined him. Together they expanded the company's products to include amplifiers and transformers for broadcasting . By 1942 the company was developing an audio system for the University of Minnesota . The plugs , sockets and patch cables developed in the process formed the basis for entering the telecommunications market.
In 1949 the audiometer line was sold and Allison left the company. ADC broadened its range and subsequently focused on transformers and filters for power lines, military electronics, and plugs and sockets for telephony.
In 1961 ADC merged with Magnetic Controls Company , a company with strong ties to the US space program.
The resulting company was called ADC Magnetic Controls . In the 1960s there were large sales of transformers, but there were no major innovations. A notable development from this time is the bantam plug, which became the standard for switching telephone connections. In the early 1970s, ADC introduced pre-wired patch panels and test equipment for telecommunications companies. In 1976 the company was the largest independent manufacturer of such test equipment in the United States.
ADC benefited from the deregulation of the American telephone market around 1983, in which seven local Regional Bell Operating Companies (RBOC) were spun off from AT&T . As a result, the American telephone market grew by 90 percent.
In the 1990s, ADC acquired various manufacturers of hardware for data communication and broadened its range to include software. This was crowned with moderate success, and ADC shares suffered massive losses as the dot-com bubble burst.
Until the very end, ADC offered network infrastructure. Three quarters of sales were generated with broadband infrastructure for public and private networks. Customers at the time included Verizon , BellSouth , Sprint Nextel Corporation , Graybar Electric and Time Warner Cable .
In 2004 the Berlin company Krone was taken over, among other things known for the LSA-PLUS insulation displacement technology . In July 2010, Tyco Electronics and ADC announced the acquisition of ADC by Tyco Electronics, which closed on December 9, 2010. In autumn 2013, Tyco Electronics informed its customers that the products of its Berlin plant will be produced in Brno from spring 2014 and that the Berlin location will be closed.
From 2015, CommScope took over the products and services under their name. The ADC company has officially ceased to exist since then.
