A new 2,100km cable extension to the existing EllaLink cable will provide a direct fiber connection between French Guiana, home of the European Space Centre, and continental Europe.
This new submarine branch will land in Cayenne, French Guiana, and include 2 fibre pairs. The system will be built by Alcatel Submarine Networks and use state-of-the-art optical technologies such as a ROADM WSS branching unit, allowing direct connectivity without regeneration from French Guiana to continental Europe with an RTD latency of less than 80ms. The new infrastructure will also enable direct connections from French Guiana to Fortaleza, Brazil.
