Fastweb uses CloudWave Optics for 300-Gbps path on long-haul backbone network

Coriant said that Italian telecommunications operators Fastweb is using its CloudWave Optics technology to deploy a protected 300-Gbps connection covering more than 950 km on its long-haul backbone network. The 300-Gbps connectivity service links Fastweb point of presence (PoP) between Rome and Milan.

Coriant said that Italian telecommunications operators Fastweb is using its CloudWave Optics technology to deploy a protected 300-Gbps connection covering more than 950 km on its long-haul backbone network. The 300-Gbps connectivity service links Fastweb point of presence (PoP) between Rome and Milan through Turin as the primary path covering 950 km, and through Florence-Bologna as the protected path covering 800 km.

The long-distance service has been launched without special amplifiers, tuning, or field hardware alterations, says Coriant. Built in 2010, Fastweb's long-haul backbone network was already equipped with the Coriant hiT 7300 Multi Haul Transport Platform to implement 100-Gbps coherent regeneration-free connections. Use of Coriant CloudWave Optics represents a technology upgrade to those systems, enabling Fastweb to optimize its initial investments and address the challenges of new cloud and hyperscale connectivity services.

Introduced in 2015, Coriant's CloudWave Optics are a range of software-programmable optical layer capabilities designed to pair with its Coriant Dynamic Optical Cloud offering to promote flexible service provisioning via a variety of optical modulation formats (see "Coriant CloudWave Optics promises flexible optical transport, greater reach").

The company anticipates future deployments of Coriant CloudWave Optics technology on Fastweb's infrastructure to implement 200-Gbps and 300-Gbps services across the backbone network nationwide, enhancing its capacity by 50% in comparison to the original design channel count.

To offer Fastweb a key performance metrics view, including OSNR margins and channel EoL, real-time optical performance results for the service are enabled and validated by Coriant Aware Technology. Throughout the years, the Fastweb backbone deployment has grown to encompass as many as 600 nodes, which Coriant references as proof that its networking technology is maximized for augmenting operators' investments in the future.

"Providing our customers with the best quality of connection is our main goal," said Andrea Lasagna, Fastweb technology officer. "A new era of high performing and reliable long-distance transport services is growing on the market faster every day. A scalable and simple network approach is required to address the increasing demand of bandwidth. We have been confident in Coriant's ability to meet our needs since the beginning and we have deployed a widespread and nationwide transport network with them. Now with the combination of Coriant hiT 7300 and CloudWave Optics technology we can light our fibers at 300 Gbps between Milan and Rome leveraging the existing infrastructure."

This past January, Fastweb added 200-Gbps regeneration-free services over an 800-km fiber network route between Milan and Rome to serve the needs of the wholesale and enterprise markets, according to Huawei. Earlier this week, Fastweb and Huawei announced the deployment of 200-Gbps capabilities on the former's Flexible Optical Network (see "Fastweb, Huawei complete 200-Gbps Flexible Optical Network deployment"). The more than 2,300 km fiber-optic network connects Milan and the south of Sicily.
