Submarine communications technology provider TE SubCom has announced the signing of a contract with Georgian internet service provider (ISP) Caucasus Online to upgrade the Caucasus Cable System. The upgrade of the 1,200km system, which provides high bandwidth connectivity between the Georgian port of Poti and Balchik in Bulgaria, will be conducted in stages over the next few years. In operation since the end of 2008, the Caucasus Cable System has served Georgian markets by providing direct access to Western Europe via a submarine fibre-optic link. SubCom’s upgrade solution will enable Caucasus Online to enhance its services through boosted international capacity. Commenting on the contract, Gia Adeishvili, CEO of Caucasus Online, said: ‘We are thrilled to continue our partnership with SubCom to gradually add network capacity to the system and better serve the region.’ The Caucasus Cable System is comprised of a two-fibre-pair point-to-point link connecting Poti with Balchik. It has an ultimate design capacity of 1.2Tbps, although a staged upgrade plan allows for the addition of 10Gbps wavelengths, using technology installed in the original system.
