EuCNC Workshop on Photonic Technologies for 5G and Beyond
Tuesday, 18 June 2019, 8:30 -13:00, room R1; Valencia Conference Center.
Future 5G networks will give rise to a wide range of new services addressing the needs of multiple vertical markets (such as connected car, smart-factories, and others). The 5G end-to-end network infrastructure will have to support extreme requirements in terms of data rates, latency, reliability, energy efficiency, etc, that need an entire set of new technologies to support it.
For the evolution toward 5G mobile connectivity, it is envisioned that optical networking and photonics, as an enabling technology, will play a major role in supporting the service and network requirements, while reducing costs through the introduction of novel converged fibre and wireless technologies. One key target for the underlying optical network is to support the distribution and collection of millimetre-wave radio signals, enabling the greatest flexibility for the accommodation of the wireless network requirements, while reducing the cost of the wireless access points (i.e., remote radio heads/antenna units at cell-cites). Moreover, new multi-access edge computing (MEC) will play a significant role of offering new services closer to the end-user.
Photonic technologies and devices allow meeting the demanding capacity and latency demands for 5G in ways that scale well to highly densified network deployments with low footprint and energy consumption. This workshop will address the role and relevance of photonic technologies to 5G and any future development in mobile networks.
With this workshop we intend to attract expert speakers and audience who will discuss the relevant photonics technology solutions – those developed by 5G-PPP projects, Photonics-PPP projects, and others – and provide a complete coverage of the 5G-related topics for which optical networking and photonics can play a key role. Such topics will include but will not be limited to: optical access network solutions supporting fronthaul, photonics for mm-wave 5G, energy efficiency optimized 5G, converged optical-wireless system solutions, flexible aggregation/Metro networks and network orchestration.

Title: 25 Gb/s Reflective Electro-Absorption Modulator Monolithically Integrated with Semiconductor Optical Amplifier for Colorless WDM-PON Application
We demonstrated colorless operation of reflective electro-absorption modulator (EAM) monolithically integrated with semiconductor optical amplifier (SOA). Semi-insulating buried heterostructure (SIBH) technology is used for waveguide definition. The EAM and the SOA are combined by using butt-joint integration. The device is operated at 25 Gb/s with non-return-to-zero modulation format in the C-band. More than 11 dB dynamic extinction ratio is obtained at 2.6 V peak-to-peak voltage. We demonstrated 10 km transmission with 3 dB penalty at 1E-3 bit error rate. The SOA allows to fully compensate insertion losses and no wavelength-dependent penalty is observed between 1530 nm and 1545 nm.

Title: Photonics as enabler for high bandwidth and low latency 5G services
Abstract: The 5G network will support multiple services with diverse and challenging requirements on bandwidh, realiability, and latency. Photonic technologies are seen as a key enabler to address these requirements. In this talk we will present concepts and solutions developed and evaluated in ongoing research projects 5G-PICTURE, MetroHaul, and Bluespace, and highlight the results from recent lab experiments and trials.

Title: Vertical integration in SiN based foundry enables new applications
Abstract: The integration of Photonic Integrated Circuits (PICs) in functional modules enables endusers to use PICs in a variety of applications. Due to the hybrid integration of multiple platforms in a single module a variety of new applications can be addressed. For the silicon nitride based TriPleX platform these range from 5G to virtual reality and sensing. The main benefit is in the low loss properties over a large wavelength range enabling these different applications. In this talk we will show the capabilities of these modules and the necessity for vertical integration. It is all about module functionality and not about PICs.

Title: Cost Efficient 5G Optical Transport Architecture
Abstract: A wide spread use of new 5G services with increased requirements in terms of bandwidth and latency will require a complete network transformation. Such transformation is expected to be especially important in metro networks due to the appearance of new technologies, such as Edge Computing or VRAN, which require ultrahigh capacity transport between Data Centres and Access Nodes. PASSION project proposes a new optical transport architecture for 5G transport enabling up to 16Tbps per fibre using low cost optical transceivers based on VCSEL technology.

Title: Real-time Dynamic Network Slicing for the 5G Radio Access Network
Abstract: Network slicing was proposed as an innovative approach for the control of the network resources. Although already exists the static slicing approach, the behavior of the wireless channel requires fast slicing techniques for resource allocation. In this presentation, we present a dynamic slicing approach for the radio access network, where the network resources are carefully assigned to guarantee the service level agreements and increase the number of served users. To prove the performance of our approach, we implemented a fronthaul testbed to emphasize the strength of our method in terms of throughput and resource utilization, compared to static slicing.

Title: Empowering your metro-access optical network with micro nodes
Abstract: The current evolution of the transport networks is very dynamic and shows many aspect of novelty. These facts challenge the telco manufacturer to propose new feature on their products in order to provide solutions for the new requirements (i.e. scaling capacity for business and mobile applications, flexibility to satisfy the dynamic network architectural changes, operational costs reduction and introducing preventive maintenance concept). Furthermore, the openness of micro node platform offers the opportunity to integrate PASSION Project technology, with the promise of outstanding performance in terms of bandwidth, flexibility and cost.

Title: SPOTLIGHT: Single Point Of aTtachment communications empowered by cLoud computing and bIG data analytics running on-top of massively distributed and loosely-coupled Heterogeneous mobile data neTworks
Abstract: To support the unprecedented demand for mobile data traffic, network providers seek novel radio access technologies that boost physical-layer link capacity, utilize additional spectrum, or further densify network topology. Towards setting the foundations of the 5G and beyond mobile data network, we analyze, design, and optimize the performance of the SPOTLIGHT architecture that aims to break performance limitations of the currently loosely inter-connected, resource-fragmented and isolated in operation mobile network ecosystem, by transforming the existing multi-layered set of attachment points to a flat coalition of massively distributed transceivers utilizing a common pool of resources that are optimally handled by a cloud-empowered network core.

Title: FiberG: Fiber everywhere, for 5G and beyond
Abstract: Fiber networks are regarded as a key prerequisite for the success of 5G. In fact, 5G features demanding requirements –and associated technical and commercial challenges– for the underlying fiber infrastructure, including higher throughput, very low latency, and increased reliability. These requirements should be considered in the context of the 5G architecture, which relies on a number of building blocks (for example, network virtualization and the related notions of fronthaul and midhaul) to enable end-to-end network slicing. This presentation provides an industry overview of the key requirements and challenges for fiber networks in the era of 5G and beyond. The presentation is based on the EXFO test, monitoring, and analytics experience with leading network operators worldwide.
