AWS today [1]announced Fastnet , a subsea fiber-optic cable that will link Maryland's Eastern Shore to County Cork, Ireland. The project marks Amazon's first wholly-owned subsea cable system after previously participating in similar ventures through consortiums.
The cable will carry data at speeds exceeding 320 terabits per second. Amazon did not disclose construction costs but expects the system to begin operations in 2028. The company is burying the cable roughly one and a half meters deep across the ocean floor. Installers will bore a horizontal tunnel from shore to shore. Amazon has added protective steel wiring to guard against ship anchors and deliberate sabotage.
