The Nippon Telegraph and Telephone Corporation has set a new data transfer record using fiber optics, topping out the old record by 4 Terabytes per second.

The speed was achieved over a 100-mile-long fiber optic cable, improving upon the previous 10 terabyte per second record by almost half. At 14 terabytes per second the transfer rate would be the equivalent of downloading approximately 3000 DVD-quality movies in a single second
