Fibre-optic Link Around the Globe (FLAG) is a 28,000-kilometre-long (17,398 ; 15,119 ) mostly- that connects the,,, and many places in between. Consider the biggest corridors: the transatlantic links between the US and Europe; the transpacific routes between the US and East Asia; the high-capacity ring between Japan, Korea, Hong Kong, and Singapore; the Europe-Asia systems via the Indian Ocean; and the Africa-Europe.
