Bending Light to our Will: 6B
- Dónal Cunningham (Asiera)
Description
We bend fibre To Our Will - but not TOO much, because Network Engineers know why a bend radius is important.This session will talk you through procuring fibre in 2026 - either for the first time, or if you are replacing aging infrastructure. We'll discuss Coherent optics - which use advanced modulations and Digital Signal Processing to transmit data at rates in the hundreds of gigabits-per-second range. We'll also showcase how nanosecond-grade time can be synchronised efficiently over an existing DWDM network.
Norway´s NREN, delivered by Sikt, is being renewed with new agreements on dark fiber and optical spectrum. The new network supports Terabit capacities, even more redundancy and lays the physical foundations for producing advanced optical services - like fiber optic sensing, high precision time and frequency transfer and quantum communication. The presentation will go through the procurement...
Demystifying Coherent Optics for Network Professionals" is a practical, vendor‑neutral session designed to give conference attendees the tools they need to deploy and optimize 100G–800G coherent transceivers in real networks. The talk translates complex physical‑layer concepts - modulation formats, parameters like OSNR, Q‑values and link budgeting - into clear operational guidance, and pairs...
This presentation details the deployment of a national-scale precision time and frequency distribution infrastructure based on White Rabbit (WR) technology, which runs directly over CESNET’s existing active DWDM network. This project moves beyond typical dark fiber deployments to offer a blueprint for NRENs seeking to maximize infrastructure utilization and support advanced services without...
