The mountains are about freedom and challenge. Forging new paths, acclimatisation and careful belaying.

Networks today demand the same approach from us: openness to multivendor solutions, skilful implementation of coherent modulation and quantum data security.



At the Light Days, you'll meet like-minded networking enthusiasts. You'll chat over coffee about lambdas, fibre and wireless coverage. You'll be among network engineers, network administrators, presales. You'll feel like you're at base camp :)


#Network technologies

We know that what participants appreciate most about the Days of Light is the short talks, equipment presentations and substantive discussions. As always, we'll show you not only the functionalities but also the applications of our systems. You'll be prepared for a solid dose of knowledge about coherent modulation, transmission systems, cloud solutions and open networks.


#Afterparty we go to Everest

We're planning a high-altitude surprise for you. Details coming soon!

Which expedition will you join 23 October 2024 in Warsaw?

The K2 team/8611 asl.

They have already reached more than one peak in capacity. Experienced in building xWDM systems and optical transmission.

IP-over-DWDM systems and 100G/400G/800G coherent optical transceiver in a nutshell. Everything you need to know to take the best from them for your network.

Why are coherent optical transceiver and IP-over-DWDM systems becoming more common in optical networks? And how does this translate into network cost efficiency? Learn about the advantages and disadvantages of IPoDWDM, monitoring and management challenges, and example applications. And for dessert, the MX800 transponder - one to rule them all

How to avoid ‘warehouse deposits’ after projects? Optical module stock management, passportisation and versatility. Practical examples.

We will propose simple solutions to tame the growing stock of spare optical modules. We will discuss how the SRD 5 environment supports workflow by enabling accurate identification and tracking of optical modules. Furthermore, we will present practical examples of how SRD 5 can be used in everyday work, highlighting the benefits of improved efficiency and reduced errors.

LAN and WiFi for hospitality and healthcare. A practical approach to network design.
DCN Europe

LANs and WLANs are now part of the critical infrastructure of healthcare facilities. Without efficient Wi-Fi, it is also impossible to imagine a modern hotel facility. Efficient patient and guest care, from booking and registration to operating robot control, relies on network access. The demands placed on Ethernet-based solutions are increasing every year as the number of users and systems grows.

Open optical networks - pros and cons. Who stands to gain, who stands to lose.

When embarking on the trail towards open optical networks, it is useful to know both the advantages and the potential risks. We will analyse who will benefit most from the technology and who may face difficulties, offering a comprehensive picture of the impact of open solutions on the industry.

Bandwidth peaks in optical transmission: 1.6T and 3.2T. Where are the limits of network technology today? Is it time to develop new regions of L-band and S+C+L-band?

What challenges do we face to bring 1.6T, 3.2T, 6.4T modules to market? How are the first commercial deployments at L-band looking, and when is it time for the next bands? We will discuss the future of optical transmission.

Does Alien Lambda have a future? How to reconcile technology integrations between users so that mutual failures do not occur?

We will work out the Alien Lambda topic from the technical side. How to measure reflectometric parameters (OTDR, OSA, coherent channel emulator) and optical spectrum in practice? How to simulate additionally activated transmission channels? Topic prepared at the request of the participants of the 16th edition of the Dni Światła conference.
