Orange said that the deployment of the 400 km FLY-LION3 undersea cable linking Comoros and Mayotte has been completed, and that the commissioning of the cable system is now expected in the third quarter. The project was unveiled in mid-2017 and targeted a 2018 delivery date.
The group’s subsidiary Orange Marine has been responsible for laying the cable between Grande Comore’s largest city Moroni and the village of Kaweni, near Mayotte’s capital Mamoudzou, where the cable has recently landed. With a total capacity of 4 terabits per second, FLY-LION3 will help improve connectivity in the Indian Ocean, linking to existing cables LION2 and EASSy, which land on the east coast of Africa.
