After conquering many peaks, it's time to take a breather. Days of Light 2026 will be the greatest expedition in our history – that's why we are preparing for it with full focus and ambition.
See previous editions of the Days of Light conference
Conference for specialists from the Telco and Data Center industries.
The mountains were our metaphor – freedom and challenge. During the 16th Days of Light, we talked about blazing new trails in the world of networks: openness to multivendor environments, awareness of the role of coherent modulation, and the need for quantum data security. This requires the same precision and courage as climbing a mountain – with good acclimatization and careful belaying.
Ready for cosmic speed? We were.
During the 16th edition of Days of Light, we looked at the future of the network – the really fast one. Although satellite telecommunications are already appearing in the background, fiber optics still has enormous potential – and it was its capabilities that were the focus of our attention. We focused not only on increasing bandwidth, but also on energy efficiency.
We embedded technologies and business models in the realities of the Polish market, and discussed key challenges in a panel discussion with representatives of the largest operators and data centers.
#NetworkChallenges.
The 15th Days of Light raced by at a speed of 800G. Inspired by Asian train prototypes reaching speeds of 620 km/h, we discussed the future of the network – fast, resilient, and ready for market challenges. We considered which systems are worth investing in to stay on track. How can the network be optimized to cope with price pressure? How to maintain independence in an unstable economic environment?
We touched on the topic of network structure modifications and trends related to IPoDWDM, and the whole thing was complemented by specific case studies from the market.
In 2026, we will be back with a new edition of the event – even more technological, high-quality, and tailored to the needs of the industry. Your opinion matters. Fill out a short survey and help us design a program that truly responds to current challenges.
