QC2 was started in early 1998 by veterans of the competitive communications industry. In its earliest days QC2 focused on outside plant projects and worked for companies such as Metropolitan Fiber Systems and Level 3 Communications building fiber network infrastructure. In 2000 QC2 began securing inside plant projects and installing optical transmission infrastructure inside Regional Bell Operating Company central offices for companies like Alcatel, Lucent Technologies, and Sprint. Beginning in 2001 QC2 added enterprise clients to its portfolio and began engineering, furnishing and installing structured cabling solutions, wireless point-to-point and point-to-multipoint outdoor networks, and wireless LAN indoor and outdoor networks.
