Common Data Link

Common Data Link

Common Data Link (CDL) is a secure U.S. military communications protocol. It was established by the U.S. Department of Defense in 1991 as the military's primary protocol for imagery and signals intelligence[1][2] CDL operates within the Ku band at data rates up to 274 Mb/s. CDL allows for full duplex data exchange.

The FY06 Authorization Act (Public Law 109-163) requires use of CDL for all imagery, unless waiver is granted. The primary reason waivers are granted is from the inability to carry the 300 pound radios on a small (30 pound) aircraft. Emerging technology expects to field a 2-pound version by the end of the decade (2010).
