First 800G network in Poland brings faster speeds, greater capacity for a digital future

T-Mobile Polska, one of the largest mobile operators in Poland, selected a coherent optical solution from Ciena (NYSE: CIEN) for its high-performance, flexible 800G network. Leveraging Ciena's technology, T-Mobile Polska will offer a new long-distance 400 Gigabit Ethernet (400GbE) service to its enterprise, content provider, and wholesale customers, to address exponential traffic growth brought on by omnipresent remote work, learning, and entertainment.

Key Facts:

* To satisfy skyrocketing bandwidth demands from data services and cloud applications, T-Mobile Polska is deploying Ciena's WaveLogic 5 Extreme coherent optics over a 6500 fully flexible colorless, directionless, and contentionless photonic system.

* Digitization is a driving force for growth in the business sector. The Ciena solution will be used to provide high-capacity 500Gbps-800Gbps wavelength connectivity, low latency, and reliability, making it possible to transport services such as 5G, cloud, and data center interconnect (DCI) at a lower cost per bit. Additionally, encryption capabilities allow for secure transmission of sensitive financial and government data.

* The network is managed by Ciena's Manage, Control and Plan (MCP) domain controller, allowing for operational efficiency and quick turnup of new services. With MCP, T-Mobile Polska can rapidly identify, troubleshoot, and repair any issues that arise.
