Construction

Laying works were completed in July 2008 by the American cable ship CS Tyco Decisive, just a couple of weeks prior to the South Ossetia War. The submarine cable was manufactured and laid by TE Connectivity and consists of two fiber pairs each carrying 96 wavelengths with a bandwidth of 100 Gbit/s providing a total bandwidth of 12.8 Tbit/s (originally 64 × 10 Gbit/s and a total of 1.2 Tbit/s). In 2011 an upgrade implemented by TE Connectivity enabled the addition of further wavelengths.

The project was led by Georgia's largest Internet service provider, Caucasus Online. Costs of construction of the submarine cable amounted to $40 million of which $35 million were funded by loans acquired from the European Bank for Reconstruction and Development (EBRD). As part of the deal, the EBRD acquired a 5.0% equity stake in the company.

The project involved further investments for terrestrial fibre optic infrastructure from and to the landing stations worth $22 million. On the Bulgarian side a fibre optic link to Varna was built while on the Georgian end a fibre optic link to Georgian neighbour Azerbaijan was laid.

Completion of the project was delayed by around one month due to the 2008 Russo-Georgian diplomatic crisis.
