With a depth of more than 2,000 meters and a sandy seabed the Black Sea is benign for submarine cables. Far beyond the reach of fishing nets and anchors large parts of the Caucasus Cable System sit safe from human risks buried in the seafloor. The absence of seismic activities along the cable's route eliminates another relevant risk factor for submarine cables.
Because of its low risk profile the Caucasus Cable System has never suffered an outage since it became ready for service in November 2008.
Launched in 2008 with an initial capacity of 1.92 Tbps the Caucasus Cable System has been upgraded from 10G to 100G technology in 2015, multiplying its capacity by a factor of 6.5 to 12.6 Tbps.
Thanks to its two separate fiber pairs, its coherent technology and TE SubCom's continuous innovations the Caucasus Cable System can be upgraded easily and smoothly leading to increased spectral efficiency and multiplied total capacity.
