Upgrading to Ciena's WaveLogic 5 Extreme (WL5e) coherent optics represents a significant advancement for Telia Lithuania's network infrastructure. This technology enables the transmission of data at speeds of 400G and potentially up to 800Gb/s, which is a considerable increase compared to the standard 100G or 200G speeds that are common in current networks. The deployment of this technology is particularly relevant given the increasing demand for high-bandwidth applications such as 5G and IoT. By enhancing the network's capacity and efficiency, Telia Lithuania is poised to offer more competitive services, which could lead to increased market share and potentially higher revenues in the highly digital Baltic region.

From a cost perspective, the adoption of WL5e also implies a reduction in the cost-per-bit transmitted, which is a critical factor for telecom operators in managing their margins. Furthermore, the emphasis on network resiliency is crucial for maintaining customer trust and minimizing potential revenue loss due to service disruptions. In the long-term, this investment in advanced optical technology could provide Telia Lithuania with a sustainable competitive advantage, enabling the company to meet future data demands and support emerging technologies.

The integration of Ciena's 6500 packet-optical platform, powered by WL5e and WaveLogic Ai coherent optics, indicates a strategic move towards energy-efficient network solutions. For telecom operators, power efficiency is increasingly becoming a key consideration due to the dual pressures of rising energy costs and social responsibility towards reducing carbon footprints. By adopting solutions that offer increased network reach and power efficiency, Telia Lithuania not only stands to benefit from reduced operational costs but also positions itself as a responsible corporate citizen in the face of global sustainability concerns.

Moreover, the ability to offer a resilient network with faster wavelength restoration and improved synchronization caters to the needs of enterprises that require high reliability, such as financial institutions and healthcare providers. This could potentially open up new revenue streams for Telia Lithuania by attracting business clients who are willing to pay a premium for enhanced service reliability.

The technical aspects of the deployment, such as quicker issue resolution and simpler service deployment, are indicative of the value that advanced network management solutions, like Ciena's Navigator Network Control Suite, can bring to telecom operations. By streamlining network operations and enabling more agile service deployment, Telia Lithuania can potentially reduce the time-to-market for new services, which is critical in an industry where speed and agility are key competitive differentiators.

Furthermore, the ability to provide highly reliable synchronization is essential for applications that depend on precise timing, such as those in the telecommunications and broadcasting industries. This technical capability could enhance Telia Lithuania's appeal in niche markets that require such stringent standards, potentially leading to specialized service offerings that could command higher margins.

Brings faster speeds, more capacity, and greater service reliability to the Baltic region

VILNIUS, Lithuania, & HANOVER, Md.--(BUSINESS WIRE)-- Telia Lithuania, a Telia Company subsidiary and leading supplier of telecom services, is leveraging Ciena's (NYSE: CIEN) WaveLogic 5 Extreme (WL5e) coherent optics to upgrade its countrywide network to support 400G and higher services and deploy the first 800Gb/s wavelength service between major cities in Lithuania.

With this deployment, Telia Lithuania can deliver more flexible, higher-capacity, and cost-effective transport services with the resiliency and power efficiency required by 5G, Internet of Things (IoT), and other bandwidth-intensive applications.

“Our mission is to be the most innovative operator in the Baltics—not just for 5G, but also transmission,” said Andrius Šemeškevičius, Head of Technology at Telia Lithuania. “We chose to work with Ciena because innovation is in their DNA, too. Ciena’s industry-leading optical technology allows us to reliably and efficiently meet our customers’ varied transport requirements—whether for access, metro, long haul, or enterprise data center interconnect.”

Virginie Hollebecque, Vice President of EMEA at Ciena, commented: “Network resiliency is of great importance for all networks in the Baltic region, considering the region’s heavy reliance on digital technologies. With an optical solution from Ciena, Telia Lithuania has a resilient network foundation that can instantly bounce back from any disruptions, minimizing downtime, ensuring service continuity, and safeguarding its communication infrastructure.”

Telia Lithuania’s new network will also utilize additional Ciena optical and network management solutions that make possible:

  • Increased capacity, network reach, and power efficiency with the 6500 packet-optical platform powered by WL5e and WaveLogic Ai programmable coherent optics
  • Faster wavelength restoration with the 6500’s flexible photonics and intelligent Layer 0 control plane
  • Quicker issue resolution and improved timing distribution for applications requiring highly reliable synchronization
  • Simpler service deployment and network operations with Navigator Network Control Suite (Navigator NCS)
