The Mid-Atlantic Crossing (MAC) cable system is a 4,600 miles (7,500 km) of submarine cable. The MAC cable system consists of two optical fiber pairs, with an initial design capacity of 1.3 Tbps.

The MAC cable lands at:

• Brookhaven Cable Landing Station, NY;
• Hollywood, FL; and
• St. Croix, U.S.Virgin Islands.

The MAC cable system was built by Global Crossing, ready for service in June 2000.

The MAC cable system is now part of CenturyLink's network assets, as well as Pan-American Crossing (PAC), South American Crossing (SAC), and Atlantic Crossing 1 (AC-1), AC-2/Yellow, Hawaii Island Fiber Network (HIFN), etc.
