Integrated radio over fiber systems
Antonella Bogoni, SSS Anna Radio-over-Fiber (RoF) technology emerges as a promising solution not only to meet the increasing demand for reliable and high-speed connectivity but also to address the challenges across a variety of sensing applications. Optical fiber, with its low loss, minimal distortions
Digital coherent receivers have, for many years, been used in high capacity, long haul optical fibre transmission systems. Recent standardisation of coherent transceivers for short reach systems – such as inter-datacentre networks – has forced a rethink of digital signal processing (DSP) design
high bandwidth characteristics, easy deployment and immunity to electromagnetic interference, ensures reliable and constant connectivity, even in harsh environments or densely populated urban areas. Moreover, beyond photonics-based RF distribution, research in RoF systems is actively pursuing additional features such as photonic up/down conversion and signal beamforming, which are driving ongoing advancements. The talk explores the pivotal role of photonic integrated technologies for future Radio-over-Fiber systems, covering its operational principles, the evolution, and the open issues. The core discussion focuses on the advancement towards photonic integration, highlighting recent innovations in hybrid and heterogeneous integration. Can Plasmonics have a role in Future Radio Access Networks? Laurenz Kulmer, ETH Zurich With wireless systems moving to higher frequencies,
due to ASIC area and power constraints. This talk will discuss some of the innovations and sacrifices required when designing DSP for short reach systems.
ADOPTION Project – Advancing Data Centre and AI Cluster Interconnects with Co-Packaged Optics for High-Efficiency Cloud Computing Cleitus Antony, Tyndall Institute
The ADOPTION project is a European Union- funded initiative under the Horizon Europe framework, focusing on developing scalable, high-performance interconnect solutions for hyperscale data centres and AI-driven infrastructures. This talk will present an overview
of the project’s approach to system integration, highlighting photonic innovations that achieve ultra-low latency, high throughput, and energy-efficient communication. Key project milestones, particularly in photonic integration and demonstrator developments, will showcase how ADOPTION is set to meet future connectivity needs and enable next-generation data centre architectures
optical solutions are being integrated closer to the base station antenna. If those trends persist, plasmonic components, which offer an abundance of bandwidth, could become a viable solution for these systems. In this talk we will cover how future remote
antenna units can profit from plasmonic components.

Reimagining High-Speed Interconnects: 100Gb/s Analog CDR Technology for Data Centers and 6G Fronthaul Raza Khan, Semtech
As data center and wireless communication technologies advance, the role of analog Clock and Data Recovery (CDR) systems is evolving to meet new challenges. While the transition to 50Gb/s PAM4 signaling initially shifted the industry toward DSP-based solutions to address
signal integrity challenges, analog retimer technology continues to offer a viable and advantageous path forward for 100Gb/s per lane interconnects and beyond. This approach provides significant benefits, including lower power consumption than traditional DSPs and ultra- low latency. This is particularly crucial in wireless architectures, especially emerging 6G fronthaul systems, where latency variation is increasingly critical with each generation. Traditional DSPs are becoming unsuitable for these advanced architectures. By adapting analog expertise from NRZ modulation to PAM4, a new generation of optical pluggables can be developed that operate at 100Gb/s PAM4 while maintaining low power consumption, ultra-low latency, and cost-effectiveness. Semtech is pioneering these innovative platforms, creating value for customers by enabling new architectural possibilities through the combination of analog latency performance and low power consumption. This approach demonstrates that analog technology has a scalable path to 100G and beyond, offering a compelling alternative to DSP-based solutions for both data center interconnects and wireless communication systems.
