WE ARE CESNET
WE UNITE SCIENCE

Chcete se podělit o své nápady a zkušenosti z oblasti správy sítí, infrastruktury či kybernetické bezpečnosti, které by mohly inspirovat ostatní? Přihlaste svůj příspěvek na komunitní setkání CSNOG 2026, které se uskuteční 21.–22. ledna 2026 v prostorách Univerzity Tomáše Bati ve Zlíně. Výzvy Call for Abstracts a Call for Partners jsou nyní otevřené a přihlášky je možné posílat do 31. října 2025.

Oblíbená podzimní soutěž v kybernetické bezpečnosti začala 6. října přesně ve 12:00. Letošní ročník s podtitulem TCC Power Grid prověří znalosti hráček a hráčů na scénářích spojených s elektrickou rozvodnou sítí. Kromě hlavních výher čekají na soutěžící ceny až do 50. místa a také speciální bonusy za nejrychlejší řešení či kvalitní write-upy.

Na začátku září jsme zajistili živé přenosy operací v rámci odborného kurzu pro ušní lékaře Central European Endoscopic Ear Surgery Course 2025, který proběhl ve Fakultní nemocnici Olomouc.

From September 12 to 14, the unique musical project Threads of Vitality will be presented at the EXPO 2025 world exhibition in Osaka, Japan. The series of concerts will use MVTP technology developed by the CESNET association, which will connect musicians on two continents in a single live performance.
Eighteen concerts will be held over three days, six each day from 7 a.m. to 12 p.m. Central European Time. The Czech National Pavilion in Osaka will be virtually connected to the JAMU Faculty of Music in Brno, allowing the audience to experience a synchronized concert featuring musical personalities from the Czech Republic and Japan. The program draws on Czech musical tradition while showcasing the possibilities of modern digital transmission.
Program and performers
The program is based on the works of Leoš Janáček, Bedřich Smetana, and Antonín Dvořák and will also feature the world premiere of a new composition by Martin Smolka entitled Nikde nikdo, kopce až po obzor, oblaka (Nowhere, No One, Hills to the Horizon, Clouds). The concept was prepared by Barbara Maria Willi, Dean of the JAMU Faculty of Music.
The performers will include:
•    Pianist Jan Jiraský, professor at JAMU and winner of international competitions
•    Pianist and conductor Kento Satsuma, student at JAMU and winner of the Janáček Competition
•    First violinist Hiroaki Goto, Brno Philharmonic Orchestra
•    Percussionist Martin Opršál, JAMU professor and head of the percussion department

Autumn 2025 will see the CESNET association host a series of exceptional concerts, connecting musicians and audiences across countries and continents. Thanks to CESNET's MVTP (Modular Video Transmission Platform) technology, we can connect performers in different parts of the world so that they can perform together as if they were on the same stage. Our participation in the EXPO 2025 world exhibition in Osaka, Japan, is the most significant event of this year.

Why fibre sensing?

In the past few years, fibre sensing has emerged as a hot new topic at prestigious events like the Optical Fiber Communication (OFC) conference, or in publications from industry and policy, including the European Commission (EC) and National Science Foundation (NSF). In this introductory article, we won’t go deep into different state-of-the-art technologies, subtle light properties used to detect unwanted events along the fibre, or AI-assisted learning. Nor will we focus on fibre sensors for medical, healthcare or control applications. Instead, we will look at terrestrial fibre sensing applications using telecommunications and data fibre networks, with a focus on two standard sensing technologies: Distributed Acoustic Sensing (DAS) and State of Polarization (SoP). DAS is the de facto standard technology that is based on well-known OTDR principles. It usually tends to generate large volumes of data. SOP, perhaps less familiar within the NREN community, is based on a principle many will recognise from antireflection sunglasses or camera lenses. It’s used less frequently but produces a reasonable amount of data.
