The LION submarine cable system consists of 2 segments :
 Segment S1 : un-repeatered between Maurice and Reunion Island,
 Segment S2 : repeatered between Reunion Island and Madagascar.

The LION connects in the “phase 1”, the following territories (cities) Mauritius Island : Terre Rouge, Ile de la Réunion : Sainte Marie, Madagascar : Toamasina.

The system offered for LION is based on repeatered technology using Wavelength Division Multiplexing (WDM). The system wavelengths are chosen to be in the 1550nm-wavelength window. It has the following key features :
 Repeaters designed for WDM applications,
 Equalisation and Dispersion Management,
 WDM Submarine Line Terminal Equipment (Nx10Gb/s),
 High reliability submerged components,
 Third generation Forward Error Correction (FEC),
 Modern Network Management System,
 Active repeater supervision.

The repeatered LION segments are designed to carry up to sixty four (64) wavelengths at 10 Gb/s per fibre pair using current technology. In initial configuration, on all segments each of the two fibre pairs are equipped with two wavelengths at 10 Gb/s with a high reliability level.
