Anritsu, Fujikura confirm equivalent core crosstalk results

Anritsu Corporation, a Japanese multinational corporation manufacturing test and measurement equipment for telecommunications, in collaboration with Fujikura, a Japanese manufacturer of cables and optical fibres, has measured inter-core crosstalk in weakly-coupled multi-core optical fibres using multiple methods and has confirmed that the results are equivalent. Both companies presented their results at the international OptoElectronics and Communications Conference (OECC 2025) in Sapporo, Japan. With the growing adoption of artificial intelligence (AI) and cloud services, the demand for higher transmission capacity in optical submarine cables and data centre interconnects is rapidly increasing. Today’s optical communications rely on single-mode fibre (SMF) and advanced signal optimisation technologies to achieve high data throughput. However, as the transmission capacity per fibre continues to grow, these technologies are approaching their physical and performance limits. Consequently, recent R&D has focused on weakly-coupled multi-core optical fibre with multiple independent cores in a single optical fibre. While this type of fibre significantly increases transmission capacity, inter-core crosstalk – caused by interference resulting from light leakage between each core – degrades the quality of transmission. This varies not only due to the optical fibre design and manufacturing, but also depending on the installation conditions, requiring evaluation of inter-core crosstalk in field conditions. Although various companies and research institutions have proposed different methods for measuring inter-core crosstalk, the measured results from each method have not yet been adequately validated. In the presented comparative evaluation, Anritsu, collaborating with Fujikura, measured inter-core crosstalk using four methods: two using optical power meters, and two using Anritsu's OTDR (Optical Time Domain Reflectometer) for measuring optical fibre loss and reflection. The evaluated four-core weakly-coupled multi-core optical fibre manufactured by Fujikura features a standard cladding diameter of 125 µm. The measured results from each measurement method were all within ±1.0 dB at 1550 nm. Consequently, any of these four measurement methods can be chosen according to the weakly-coupled multi-core optical fibre application scenario, such as R&D, Manufacturing, and Installation and Maintenance (I&M), with assured consistent correlation regardless of which method is used. Furthermore, these results should assist with future standardisation of weakly-coupled multi-core optical fibre. Anritsu says it will continue to contribute to the practical implementation of next-generation optical communications technology by providing test solutions for weakly-coupled multi-core optical fibres.

1/3 of UK businesses losing £4m a year due to network failures

Network instability is taking a serious toll on UK businesses, with over a quarter (33%) reporting revenue losses of up to £4 million due to network outages or poor performance. Alarmingly, an additional 18% have experienced losses exceeding £4 million. These findings come from an IDC InfoBrief, entitled Enterprise Horizons 2025: Technology Leaders Priorities: Achieving Digital Agility, commissioned by telecommunications company Expereo. Following a series of high-profile IT disruptions over the past year, ranging from cybersecurity breaches to connectivity failures, half (50%) of UK businesses have been compelled to re-evaluate their technology infrastructure and 35% of UK tech leaders say it’s caused networking and connectivity to rise higher up the C-suite agenda. Perhaps as a result, networking/connectivity now comes out on top in terms of the technologies UK businesses will prioritise in terms of financial investment over the next 12 months (40%). This is followed by cybersecurity (39%) and AI (35%). Last year, AI took the top spot (42%), followed by cybersecurity (37%) and networking/connectivity (35%). This highlights that AI is no longer the most urgent priority, being beaten by both networking and security. The urgency is well-founded. More than one in four UK organisations (27%) say that inadequate network and connectivity performance is actively threatening their growth plans for the coming year. At the same time, nearly half (49%) report that network limitations are holding back their ability to support large-scale data and AI initiatives. Alarmingly, just 5% of businesses in the UK believe their networks are fully prepared to support AI without any barriers. “To drive a sustainable competitive advantage, connectivity is no longer an IT concern – it’s a strategic business imperative," argues Ben Elms, CEO of Expereo. “This research confirms what many technology leaders are already experiencing firsthand: connectivity is now the backbone of business. As organisations race to adopt new AI solutions, the C-suite must treat network performance with the same urgency as cybersecurity and AI itself - because without it, businesses simply cannot succeed." Having the right talent in place is also critical for building and maintaining the robust network and connectivity infrastructure businesses need to thrive. However, the research suggests this may be easier said than done. Cybersecurity continues to top the list of areas where organisations struggle to find or retain skilled professionals (44%), closely followed by networking (40%). As a result, 40% of UK businesses say they plan to increase their reliance on external partners, such as vendors or managed service providers, to help bridge the networking skills gap.

MCR2 offers a design PUE of 1.25, a 100% power availability SLA, and a focus on sustainability, security, and "operational excellence." Security is further bolstered by the inclusion of an on-site police-linked Alarm Receiving Centre and the site’s NSI Gold certification (BS5979 SOC). Emma Taylor, Labour Councillor for the Sharston Ward, comments, “Data centres are a critical part of our data infrastructure in Manchester and, as anchors for investment, play a really important part in supporting local growth. This multimillion pound investment by Datum really demonstrates the confidence in the region and I’m really excited for what the future holds. As someone who grew up just metres from the site of what is now MCR2, I’d like to thank the team at Datum for bringing a bit of life back into the fringes of Wythenshawe town centre.” Datum’s design and construction partner Keysource delivered the facility. Jon Healy, Managing Director at Keysource, a Salute company, adds, “It’s been great to deliver on another successful project with Datum Datacentres. We set out to challenge the status quo and drive the highest possible standards across the project design, construction, and sustainability. Collaboration between Datum and Keysource has been at the fore to deliver on key business drivers and is testament to our talented people involved. We look forward to the next project.” For more from Datum Datacentres, click here.

Industry analysts urge data trust over AI hype

As organisations continue to increasingly embrace AI to unlock new operations, industry analysts - at the Gartner Data & Analytics Summit in Sydney - urged a critical reminder that without trustworthy data, even the most advanced AI systems can lead businesses astray. Amid rising interest in generative AI and autonomous agents, business leaders are being reminded that flashy AI capabilities are meaningless if built on unreliable data. According to information technology research and advisory company Gartner's 2024 survey, data quality and availability remain the biggest barriers to effective AI implementation. If the foundation is flawed, so is the intelligence built on top of it. While achieving perfect data governance is an admirable goal, it's often impractical in fast-moving business environments. Instead, analysts recommend implementing "trust models" that assess the reliability of data based on its origin, lineage, and level of curation. These models enable more nuanced, risk-aware decision-making and can prevent the misuse of data without stalling innovation. Richard Bovey, Chief for Data at AND Digital, comments, "Trust in data isn't just a technical challenge, it's deeply cultural and organisational. While advanced tools and trust models can help address the reliability of data, true confidence in data quality comes from clear ownership, clear practices, and company-wide commitment to transparency. "Too often, organisations are rushing into AI initiatives without fixing the basics. According to our research, 56% of businesses are implementing AI despite knowing their data may not be accurate in order to prevent from falling behind their competitors. "Businesses must consider taking a data and AI approach to their technical operations to build trust, cross-functional collaboration, and ongoing education. Only then can AI initiatives truly succeed." At the summit, autonomy was a central theme. AI systems may act independently in low-risk or time-sensitive situations, but full autonomy still raises concerns as, while users accept AI advice, they're still adjusting to autonomous AI decision-making. Stuart Harvey, CEO of Datactics, argues, "One of the biggest misconceptions we see is the belief that AI performance is purely a function of the model itself, when in reality, it all starts with data. Without well-governed, high-quality data, even the most sophisticated AI systems will produce inconsistent or misleading results. "Organisations often underestimate the foundational role of data management, but these aren't back-office tasks, they're strategic enablers of trustworthy AI and those businesses that rush into AI without addressing fragmented or unverified data sources put themselves at significant risk. Strong data foundations aren't just nice to have in today's technical landscape, they're essential for reliable, ethical, and scalable AI adoption." Gartner predicts that by 2027, 20% of business processes will be fully managed by autonomous analytics and these "perceptive" systems will move beyond dashboards, offering proactive, embedded insights. The company also believes that by 2030, AI agents will replace 30% of SaaS interfaces, turning apps into intelligent data platforms. To thrive, data leaders should thus prioritise trust, influence, and organisational impact, or risk being sidelined. For more from Gartner, click here.
