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.

Connectors for data centres can improve energy efficiency

Energy costs can account for more than 50% of the total operating expenses of a data centre. To calculate the exact effect of power usage from connectors in data centres, HARTING has compared the power consumption of three different connector solutions in its independently accredited test laboratory. One of the connectors tested was the HARTING Han-Eco. The other two were CEE (IEC 60309) plugs from different manufacturers. The results showed that the Han-Eco connector reduced power wastage by up to 50% by using low-impedance contacts. These contacts reduce the power lost in connections and significantly improve the Power Usage Efficiency (PUE) of data centres. As a result, one hyperscale data centre with 15,000 racks could achieve annual power consumption savings of around £100,000.

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.
