After the 2011 collaboration on the first 100-Gbps link in Eastern Europe (see "ETT, Ciena deploy first commercial 100G network in Eastern Europe"), Ukrainian telecommunication operator Eurotranstelecom (ETT) and Ciena announced the nationwide rollout of Ciena’s 100-Gbps coherent optical technology in ETT’s backbone network. With this deployment, ETT extends its original 100-Gbps network connecting Kiev and Kharkov to cover all major Ukrainian regional centers, including Lvov, Donetsk, Odessa, and Dnepropetrovsk. It also provides high-speed support for traffic from European, Ukrainian and Russian operators.

“As 100-Gbps adoption gathers momentum globally, large demand-driven deployments such as this one are also testament to the bandwidth explosion that the Russia/CIS region is going through at the moment,” says Sergei Fishkin, Ciena’s regional managing director for Russia, CIS and the Baltics. “With the growing adoption of high-bandwidth applications such as cloud computing, high-capacity networks are becoming more instrumental than ever before in allowing operators to meet the requirements of their customers.”

With the rollout, ETT can operate 10-, 40-, and 100-Gbps channels simultaneously while providing a seamless upgrade to higher capacities as bandwidth requirements on its network change in the future.

ETT operates its own underground fiber-optic cable network along railways, covering all major regions in Ukraine. The operator has its own national DWDM, SDH, and IP/MPLS networks, offering IP transit, data and voice transmission, lambda services, collocation, dark fiber renting, and maintenance services to clients.
