The invisible infrastructure of global connectivity

The SMW-4 (SEA-ME-WE 4) submarine cable is one of the most important and most widely used cable systems in the world, connecting Southeast Asia, the Middle East and Europe on a continuous route. As part of the legendary SEA-ME-WE cable family, SMW-4 has been a mainstay of digital connectivity between three of the world’s most important economic regions since its commissioning. With over a dozen landing points along the entire route, SMW-4 is one of the most widely deployed cable systems in the Indian Ocean. Submarine cables such as SMW-4 form the invisible foundation of global data traffic, with over 99% of international data flowing through them rather than through satellites or the cloud.

Route & connection

SMW-4 connects Singapore and Malaysia in the east with France and Italy in the west, passing through the Indian Ocean, the Red Sea and the Mediterranean. Along the route, the cable ends up in Thailand, Bangladesh, India, Sri Lanka, Pakistan, the United Arab Emirates, Saudi Arabia, Egypt and several European countries. With a total length of around 20,000 kilometers, SMW-4 is one of the longest and most widely branched cable systems on the Asia-Europe route.
