Ciena publishes report on wave services demand

Ciena, an American networking systems and software company specialising in optical networking equipment, has compiled a new report on wavelength services that explores the key drivers of the need for high-speed connectivity. The report examines the critical role of wave services in enabling the expansion of interconnected data centres driven by artificial intelligence (AI), the growing importance of low latency and data sovereignty for AI workloads, and the build-out of terrestrial and critical submarine network infrastructure. It also highlights the pivotal role of managed optical fibre network (MOFN) business models to expand high-speed connectivity into new geographies and markets. “As cloud providers scale data centre networks to address AI performance requirements, wave services must also evolve in terms of capacity, coverage, latency, and route diversity,” says Mark Bieberich, Vice President of Portfolio Marketing, Ciena. “Demand for wave services is growing steadily worldwide as data centre network expansion requires increasingly high-capacity interconnection among various types of network operators and end users.” The total wave services circuits market in the US grew nearly 8% in 2024 and is projected to grow steadily through 2029, based on research from Vertical Systems Group. It observed an increasing use of wave services for cloud on-ramps, which is demonstrated by the metro geographical scope (41%) along with the dominance of retail customers (58%). The report states that, from 2024 to 2029, growth in 400G circuits is set to soar, while 100G circuits will see a steady rise and 10G circuits will experience modest growth. Wave services are the foundation of most high-capacity networks, particularly when connectivity to or between data centres is involved. High bandwidth, protocol transparency, and low latency are some of their fundamental characteristics. Wave services can either act as end services or support higher-layer services. Based on Dense Wavelength Division Multiplexing (DWDM) technology, they enable massive data-transmission bandwidth over a fibre pair. Currently, wave services are dominated by 100G and 400G connections. There is still a high volume of 10G services deployed, but they are being upgraded to 100G at a steady pace. Ciena’s report also looks at the growth of submarine cables. It highlights that a record 161,100km of submarine cables are planned to become ready for service (RFS) in 2025, dwarfing the previous high of 121,000km becoming RFS back in 2001. “With infrastructure expanding rapidly and resource constraints increasingly shaping growth, anticipating demand has never been more important,” continues Mark. “Network operators providing wave services can seize this moment by proactively routing new submarine cables to emerging data centres and innovating to address these challenges. Differentiation through greater route diversity, low-latency connectivity, and compelling managed services is key to staying ahead.” The report provides an analysis of the current industry landscape, evaluating key trends and identifying factors poised to influence the market in the coming years.

EUDCA’s research affirms critical importance of data centres

The European Data Centre Association (EUDCA), a trade body representing data centre operators, suppliers, and stakeholders across Europe, has announced the publication of its inaugural State of European Data Centres report, in collaboration with European National Trade Associations (NTAs). The new report marks an important step in documenting and recording the state of the industry, allowing greater ongoing analysis and insights, tracking progress and development, and reflecting a vibrant industry that while experiencing challenges, has potential to be at the heart of a digital Europe. Michael Winterson, Secretary General of the EUDCA, says, “Europe’s digital economies could not have been established without the backbone of data centres that provide digital sovereignty while contributing significantly to GDP. The State of European Data Centres 2025 provides a benchmark of this vital industry and a reference point for informed, data-driven decision-making as we continue building Europe’s digital future.” According to the report, the data centre industry contributes significantly to Europe’s socio-economic landscape. Colocation data centres alone were responsible for €30 billion in GDP in 2023, expected to reach €83.8 billion by 2030, with the creation of thousands of direct and indirect jobs. The market is expanding rapidly, driven by artificial intelligence (AI) and digital service growth, with demand outstripping supply and attracting billions of euros in investment. Major centres of activity include Frankfurt, London, Amsterdam, Paris, and Dublin (FLAPD), with intense activity in emerging hubs in the Nordics and Southern Europe. Additionally, new metropolitan hubs are emerging in and around cities such as Barcelona, Rome, and Athens. “A key implication from the report,” continues Michael, “is the need for data centres, as large energy consumers, to become flexible energy partners to grid providers.” Sustainability data shows that more than a quarter (28%) of operators have invested in on-site renewable energy generation capability, and 41% plan to do so. In support of these efforts, 28% are planning on installing battery energy storage systems (BESS) within the next two years. Currently, nearly a quarter (22%) of data centre operators provide grid stabilisation or energy trading capacity to energy grids, greatly facilitating further utilisation of renewable energy sources (RES). This will almost triple (59%) in the next two years. All of this means that data centre operators, through increased resilience and energy independence, can engage with grid operators to relieve stress on grids, while providing supports such as grid stabilisation services. The report finds the industry faces challenges related to power availability, sustainability, and regulatory compliance as new reporting obligations recently came into effect. More than a third (36%) said that regulatory compliance will be a challenge over the next three years. However, these challenges also present opportunities for innovation in energy efficiency, flexibility, and heat reuse. The sector's continued growth will necessitate ongoing investments in sustainability to minimise environmental impact. Another bright spot is improvement in water usage. Of those operators who reported water usage effectiveness (WUE), the average was 0.31 litre per kWh for 2023, well below the Climate Neutral Data Centre Pact (CNDCP) target of 0.4 l/kWh for water-stressed areas. The industry is also advancing technologies such as liquid cooling and heat reuse to improve efficiency and reduce its environmental footprint. Currently, half of operators have residual heat coupling capability, with a further 38% expected in two years. Already, three quarters of operators have energy or environmental management systems in place. The data centre industry also faces significant challenges, including power supply constraints, permitting delays, and a growing skills gap in technical fields. More than 75% of survey respondents consider access to power as the biggest challenge for the sector in the next three years, despite a willingness to invest in alternative solutions to access power. Energy costs are also a concern, as rising wholesale prices impact operators. The additional responsibility of regulatory compliance was also significant, with more than a third (36%) citing it as a major challenge in the near future. There are significant concerns that duplication and redundancy in reporting frameworks will deter compliance, reducing effectiveness and frustrating regulatory goals.

Optical cable removes barriers to delivering 800G

A new proposal for long-haul optical network cables aims to ‘break through the glass ceiling’ of data transmission limits to ensure the ever-growing demands of data centres can be supplied. A new whitepaper from fibre cable experts Acome Group and Sumitomo Electric Industries says that existing optical fibre cables will only be able to meet the long-term transmission capacity needs of European data centres at a significantly higher cost and degraded environmental footprint. Conventional G.652.D optical fibres struggle to transmit data rates at and above 800 Gb/s over distances further than a few hundred kilometres. Over longer distances, such as between two data centres, signal regeneration or additional optical amplification is needed which adds complexity and costs for network owners. “With AI, cloud services, and the growth of hyperscale data centres dramatically increasing demand for bandwidth, telecom infrastructure must evolve to support high-capacity, long-distance transmission,” comments Xavier Renard, Telecom Marketing Director at ACOME. “It’s also crucial that we consider the longevity of the network. A network is not a static asset. It’s constantly evolving, so it’s essential that the fibre used is correctly selected to support future bandwidth over decades of use.” Acome and Sumitomo Electric have developed a new hybrid solution that aims to allow network operators to deploy a single, universal cable that supports both current and future network needs. Upgrading to 800G and above requires fewer repeaters to amplify the optical signals and can also avoid the need for signal regeneration. Their solution combines two existing fibre grades to provide a cable solution that should enable longer transmission distances, higher data rates per wavelength, and reduced infrastructure requirements – all of which are key enablers of energy-efficient, scalable, and future-proof optical transport networks. “PureAdvance fibres, compliant with ITU-T G.654.E, are contributing to evolve long-term network and transmission technologies. For example, combining G.654.E with G.652.D can maximise flexibility and futureproof the network,” adds Fumiyoshi Ohkubo, General Manager, Market Development & Engineering Department of Optical Fiber & Cable Division at Sumitomo Electric. This hybrid approach intends to create pathways for future upgrades to high-capacity, using coherent transmission, and enable a smoother migration to next-generation network architectures without needing full infrastructure overhauls.

UK Government announces new apprenticeship initiative

Young people in the UK are set to benefit from 120,000 new training opportunities as part of what the Government calls a "radical skills revolution," giving them the chance to develop skills where they are most needed across the workforce to "rebuild Britain." An overview of the announcement: · Construction, health and social care, engineering, and the digital sector are among those set to benefit the most from the new opportunities. · There is a refocusing of funding away from Level 7 (masters-level) apprenticeships from January 2026 – which has been criticised. · There is to be an implementation of a 32% increase in the Immigration Skills Charge, which will deliver up to 45,000 additional training places to upskill the domestic workforce and reduce reliance on migration in priority sectors. In response to this announcement, within which the digital sector has been cited as one of the key areas benefitting from the new opportunities, comments have been made by Mike Meyer, Managing Director of Portman Partners and Board Member of the Data Centre Alliance. Mike has an extensive background in recruitment and talent development within the digital infrastructure sector, having spent over 25 years within the industry with first-hand experience across Datacenter, Digital Infrastructure, IT, and Telecoms prior to moving into Executive Search. He has also spoken numerous times on the topic of talent development and bringing up the new generation of data centre professionals, notably at the East London University and at the Tech Capital International Finance Forum. “It's encouraging to see the Government investing in skills development across sectors for the next generation of young talent,” says Mike. “With the digital sector being among those set to benefit, I hope to see investment in the skills required for the digital infrastructure industry to help attract and nurture young professionals that the sector desperately needs to sustain itself. “With the growing demand for data centre capacity continuing to create the need for larger facilities, this has brought with it an unyielding need to fill the ever-increasing job openings in the sector. Though growth is an excellent problem to have, a future pool of fresh, young talent is imperative in a sector that is rapidly aging, with an average age of 53. “The Government’s ambitions to strengthen the UK's leadership in advancing and applying AI is creating demand for even larger, more powerful data centres. Alongside significant capital investment, such as the planned construction of the UK’s largest AI data centre in Essex in 2026, there will be an ongoing need for a steady pipeline of skilled talent to design, construct, and manage data centres. The new initiative from the Government is a positive sign that the industry is heading in the right direction.”

Roxtec Middle East reports record data centre sales growth

The Middle East’s rapid development in the data centre sector, supercharged by AI and cloud computing demand, is driving growth in the region for safety seal manufacturer Roxtec. Dubai-headquartered Roxtec Middle East is expanding from working on six data centre projects in 2023 to more than 20 in 2025, including programmes for major global players and AI ‘hyperscalers’. Swedish-owned Roxtec today announced it is gearing up for more demand for its products over the next 18 months, following the recent development deal to allow the UAE to buy large volumes of US-made AI chips, announced during President Trump’s recent visit to the region, and deals signed by major American companies to develop the AI sector. In a major development, the UAE and US have signed an agreement for the Gulf country to build the largest artificial intelligence campus outside the US. The 10-square-mile AI campus in Abu Dhabi will be powered by a five gigawatt data centre and will be operated by American companies and supported by Emirati firms G42 and MGX. The initiative includes collaborations with major tech companies such as Nvidia, OpenAI, Amazon Web Services, and Microsoft. These partnerships aim to position the Gulf region as a global leader in AI development. Roxtec, a global leader in the manufacture of cable and pipe transit systems, based in the Jebel Ali Freezone, has revealed it is currently in discussions with several companies looking to develop and build the next generation of HPC (High-Performance Computing) data centres, designed to handle intensive AI and Big Data workloads. The company provides specialised seals for cable and pipe penetrations that secure data centres against fire, water ingress, and air leakage, and protect against electromagnetic interferences that can create outages. The sector now represents more than 25% of its infrastructure business unit sales with a potential to reach 50% in the next 18 months. Roxtec is currently active on projects in the Gulf states of UAE, Qatar, and Oman, including new-build centres as well as refit and refurbishment work. The high energy efficiency needs of ever-larger centres which house the supercomputers that run AI systems, and the climate change and environmental challenges being faced across the region, are increasing the demand for resilience. A shift towards modular construction is also helping Roxtec’s growth and scale-up plans as a valuable part of the supply chain. To cater to the growing needs of the market, Roxtec is launching two new products for the Middle East: FlamePlus, which offers a sealing system, addressing the shift toward modular and prefabricated builds, and its Software Suite, which offers a digital lifecycle management platform for cable and pipe transits. In addition, Roxtec has confirmed appointment of a dedicated manager in Abu Dhabi for its data centre operation. Mohammed Abrar, Roxtec Business Unit Head of Infrastructure and Industry, says, “We’re seeing massive demand for our products, powered by the continued rise of AI, the increasing capacity that is required and the large-scale investments that are building a flourishing ecosystem. We’re forecasting that the growth we are seeing will accelerate even further on the back of the continued development of the sector across the Middle East, driven by massive US collaboration and the focus of governments in the region to unlock the opportunities AI presents. “That focus on partnerships in AI and data centres means billions of dollars being poured into their construction, putting Gulf nations at the forefront of the new technology and AI development, which is great news for the supply chain. We are currently working with a number of tech giants, including global hyperscalers. The speed of development is continually increasing, with new centres going from the design stage to build completion in as little as 11 months. “With increasing capacity in these centres and their high energy efficiency needs, there is great demand for airtight sealing to avoid cooling loss. HPC data centres require significant liquid cooling and, as a result, the management of a myriad of pipes. Operators are putting special focus on seals as they work to manage cooling and recycle excess heat. As a result, our expertise and range of products are proving invaluable. We have developed industry leading tools for managing cable and pipe transits. “Climate change and environmental challenges, including sandstorms, unprecedented rainfall, and flash floods, are creating more demand for resilient sealing solutions and we are supporting a number of clients as they look to protect their infrastructure from these threats. “Our expertise in the complete project life cycle, from design to supply and installation, coupled with training and inspection services, is giving us an edge. As the world moves towards increased reliance on data centres and AI, robust infrastructure is essential. A shift towards modular construction is also helping create demand for our services, with our specifically designed solutions that support faster instillations on these sites.”
