The Terabit era has begun, thanks to proliferation of bandwidth-hungry devices; and consumers’ thirst for high-speed connectivity. Catering to these demands and to keep up with the competition, many carriers have been expanding their network.

One among them is TeliaSonera (News - Alert) International Carrier (TSIC), a global IP (Internet protocol) carrier operating a fiber optic network connecting 200 PoPs across Europe, North America and Asia.

Recently, TSIC completed an expansion with the help of Infinera’s (News - Alert) intelligent transport network, the DTN-X platform. This expansion will bolster its presence in the North American market.

With the help of Infinera DTN-X platform, TSIC was able to add an additional 18,400 km of fiber to their existing North America network. This will help the carrier to reach 44 points of presence (PoPs) by the end of this year, which in turn will facilitate diverse connection capabilities to Latin America.

Infinera’s DTN-X is a multi-terabit packet optical network (P-OTN) platform. It features large-scale photonic integrated circuits (PIC), built-in OTN (ITU G.709) switch with 1 Gb/s granularity and generalized multi-protocol label switching (GMPLS) based network intelligence.

Designed with investment protection and programmable coherent technology in mind, the DTN-X helps operators to optimize their fiber assets, scaling to 5 Tb/s per bay, and to 1 Tb/s of slot capacity allowing 10 Tb/s per bay and 100Tb/s in a multi-bay configuration in the future.

Some of the other key features of the DTN-X platform are: PIC-based FlexCoherent super-channel line system; digital plug and play automation, apart from GMPLS intelligence; network convergence of dense wavelength division multiplexing (DWDM), OTN and future MPLS switching; 50 percent less power consumption compared to competitors; and 33 percent less footprint.

With the help of Infinera’s technology, TSIC was able to increase revenues with highly reliable, differentiated services while reducing operating costs through scale, multi-layer convergence and automation.

According to sources, TSIC was the first to deploy an Infinera Intelligent Transport Network and Instant Bandwidth (News - Alert) technology in North America, thereby reaching 35 PoPs in 23 cities.

Infinera’s Intelligent Transport Network has been implemented throughout TSIC's North America network as well as part of its European backbone.

"Today's end users want everything, anywhere, instantly. This expansion is about supporting that and the increasing interest for our offering in the Americas," said Erik Hallberg, President, TeliaSonera International Carrier. "The Infinera Intelligent Transport Network helps strengthen our global backbone and demonstrates our commitment to be ready to carry the big ideas of tomorrow."
