News and Business

Deutsche Telekom Global Carrier has introduced a new route along its Lambda network, spanning from Sofia, Bulgaria, to Varazdin, Croatia, using Ciena’s WaveLogic 5 Extreme 800G built upon the company’s DWDM architecture This, says DT, establishes a trajectory between Sofia and Vienna, Austria, that is significantly shorter than the previous pathway, resulting in a 5ms latency improvement. The service also enhances diversity within the region, as the German provider offers several Points-of-Presence (PoPs) from Varazdin, including locations such as Zagreb or Budapest, and more recently, with the launch of a new PoP in Balchick, Bulgaria, establishing a gateway that is the shortest route between Asia and Europe. The new route also presents a viable substitute for the heavily utilized Budapest – Vienna connection as it circumvents that area.

Deutsche Telekom Global Carrier has is an early adopter of 400GE technology. Compared to 4 x 100GE, 400 GE reduces the need for multiple interfaces, ports, power, space, equipment, and cooling, resulting in a more sustainable and efficient solution. The organisation also offers encryption for data while in transport, with an end-to-end protection service called Encrypted Lambda.

Beatrix Kapitany, head of Sales Network Infrastructure Solutions at Deutsche Telekom Global Carrier added, “While our primary focus lies in delivering 100G services along the Sofia to Zagreb route, we are capable of catering to bandwidths ranging from 1G and 10G all the way up to 400G, thus tailoring our service to fit client needs. Customers can simply reach out to us, as we are always able to develop an appropriate solution.”
