Sustainability in Telecom Services and Technologies

Wednesday 29th March 2023 13:00 – 15:00 (BST) / 14:00 – 16:00 (CEST)

Fibre is probably the most eco-friendly means of enabling telecommunications in terms of the materials used and the manufacturing processes, particularly in comparison to copper. Components such as transceivers are becoming more power-efficient, meaning things like hyperscale data centres require less power. Also, many companies are revamping their production facilities to run on renewable energy in an effort to become a more sustainable industry.

Helen Xenos, Senior Director, Portfolio Marketing, Ciena

The surging demands of our hyperconnected world means businesses must continue to adapt and take action to transform their networks. Delivering a massive amount of bandwidth in an automated, flexible way – not just through the core of the network or across the ocean, but even closer to the network edge and the end customer – will continue to be a key imperative for network providers. At the same time, consumer demand for more capacity and bandwidth is resulting in greater energy use. Now more than ever, network providers are looking for ways to scale networks while using less equipment, reducing cost, space and energy use. In this webinar, Ciena’s Helen Xenos will explain how greener networks are made possible by continuous innovation in coherent optical technology, which supports exponential capacity increases while keeping power and energy consumption in check.

Dr. Anders. S.G. Andrae, Assistant Chief Expert of Environmental Protection Technology,  Huawei Technologies

The data to be handled in the future will be very large and therefore the networks of the future have to possess certain characteristics. The foreseen trends are shown for key metrics and power saving technologies listed. Macro graphs placing fixed optical network production and use in a larger context are presented. The electricity savings potential under different scenarios are discussed. Policy and technology implications are proposed.

Green ICT – Challenges and Requirements
We give an overview on ICT environmental aspects, focusing on (wireline) network equipment. Relevant drivers and challenges related to ICT’s environmental footprint are identified. This includes the question of longevity vs. energy efficiency. This is complemented by a brief overview on legal and other relevant requirements related to (environmental) sustainability in ICT.

Jens Malmodin, Senior Specialist, Ericsson
The Energy and Carbon Footprint of ICT and Entertainment and Media (E&M)

The energy and carbon footprint of ICT have been constant since about 2010 while the footprints of E&M have decreased significantly as e.g., paper media has “moved online” and a whole range of consumer electronics have been reduced drastically as their functions are now included in smartphones. TVs have also become more energy efficient even as they have become larger.

Note the constant or decreasing footprints despite mobile subscriptions have increased from about 5 to more than 8 billion, broadband lines have more than doubled to 1.2 billion, Internet users have increased from about 2 to more than 5 billion people, and TV-households have increased 20%. At the same time from around 2010, network data traffic has increased about 20 times!

Aviation has typically been compared to ICT, but the carbon footprint of aviation was about 2 times larger in 2010 and about 3 times larger in 2019 before the pandemic. And then air travel is only used by about 10% of all people on the planet only a few times per year, while ICT is used by most people every day for hours.

How is this possible you may ask. Continuous improvements and miniaturization year by year, and sometimes larger steps due to brand new technologies, has not only led to lower energy consumption, but also less overall use of materials.

His speciality is the application of sustainability assessment methodologies to ICT solutions from cradle–to–grave. Lately – apart from compliance, LCA and electricity footprints – he has focused mostly on Circular Economy-related topics in European Telecommunications Standards Institute’s (ETSI) e.g. disassembly of server and data storage products, International Telecommunication Union (ITU-T) e.g. Product Circularity Scoring, International Electrical Commission (IEC) e.g. avoided emissions, and academia. Since 2009 Dr. Andrae has been the Rapporteur and Editor of several ETSI and ITU-T Standards and Technical Reports about LCA and Circular Economy.
His current research interest is development and application of LCA to ICT to better understand footprint evolution, trade-offs, supply chains and business models as far as: data management, waste minimization, and green indicators. In ETSI standardization he helps define new LCA methodologies for ICT consumer and network infrastructure goods as well as product information formats. He has previously published three books and 40 peer–reviewed journal papers. Since 2008 Dr. Andrae has been with Huawei Technologies in Sweden now as Assistant Chief Expert of Environmental Protection Technology.

Webinar 2: Why we need new architectures and support systems

Wednesday 21st June 2023 13:00 – 15:00 (BST) / 14:00 – 16:00 (CEST)

Sponsored by:



The unique challenges of fibre-based networks are increasing as operators face additional requirements from deeper penetration into rural areas, replacement of copper as well as new threats. Architecture changes and advanced support systems are critical to enable more sophisticated optical designs and efficient operations to meet this need.

How to stretch limits of PON networks by deploying novel splitting structures
Erik Pennings, Business Development Manager, Ensure

It is an important goal for many to create an increasingly interconnected world. High-speed internet has allowed us to stay connected, to work from home, and much more. Now that PON networks are going up in speed and/or reaching more of us, e.g. also in rural areas, there are situations where carriers can be short on fiber or run into power budget issues. For these situations, deploying novel splitting structures, such as asymmetric splitters, can offer great benefits. In the webinar, it will be detailed how these components can help and a number of interesting use cases will be discussed.

What should you consider when choosing an OSS/BSS for your fiber business?
Johan Hjalmarsson, NetAdmin

Johan discusses what to consider when choosing an OSS/BSS for a fibre business. He emphasizes the importance of OSS/BSS in the industry and highlights key factors to consider, including important processes and how fibre networks differ compared to other access technologies. Johan suggests that investing in the right tools from the beginning is crucial for building a successful fibre network.

Evolution of long-haul optical network decision support systems, adopting AI/ML
Andrea Di Giglio, Telecom Italia

The design of optical lightpaths is a complex task, involving different expertise. Often, an important margin is a part of the project both to face of the ageing of the system and to be robust to unpredictable characteristics of the components. For this reason, machine learning techniques, based on learning on set-up lightpaths can be useful for new design or for a quick recovery after a fault. Furthermore, the growing occurrences of hacker attacks on optical layer can be faced by a classification and root cause analysis based on AI/ML techniques.
