The PRIZM TMT ferrule uses expanded beam technology with precision-aligned microlenses, rather than direct fibre contact. This approach is intended to improve installation reliability, reduce sensitivity to contamination, and support faster deployment. According to the companies, these characteristics are suited to large-scale AI environments, where high connection density and consistent performance are required. For more from Corning, click here.

SUBCO expands Australia network route diversity

SUBCO, an Australian developer of undersea fibre optic cable networks, has expanded its Australian network with additional route diversity between Sydney and Melbourne, alongside new data centre access points across major cities. The company says its Sydney–Melbourne connection now operates across two geographically independent paths, combining subsea and terrestrial infrastructure to improve resilience on one of the country’s busiest corridors. On the Sydney–Perth route, the Indigo Central and SMAP systems provide two separate cable paths with distinct geographic routes. Both systems operate independently, with separate landing stations, submarine line terminal equipment, and data centre connections to reduce the risk of disruption from a single incident. Bevan Slattery, founder and Co-CEO of SUBCO, explains, “Diversity has traditionally been something customers needed to engineer themselves, engaging multiple providers and hoping the underlying paths were physically separate. SUBCO’s strategy has been to own and operate diverse assets and deliver them as a single, fully integrated offering.” Expanded data centre connectivity SUBCO has also introduced new access points across Sydney, Melbourne, Adelaide, and Perth, extending connectivity to its domestic and international cable network. New connection locations include facilities operated by NextDC, Equinix, AirTrunk, and CDC Data Centres. The update forms part of a wider infrastructure expansion programme, which also includes the APX East subsea cable project. This planned system is expected to connect Australia directly with the mainland United States, with service targeted for late 2028. According to SUBCO, APX East will provide a direct subsea route without intermediate landing points, and will land north of Sydney’s existing cable protection zone to increase geographic separation.

Barriers to colocation could hold back DC market

Speaking from the Space Comm Expo Europe event in London, Strategies in Satellite Ground Segment (SSGS), the organiser of the world’s only conference dedicated exclusively to the satellite ground segment, has warned that the global success of data centres is at risk if barriers to their colocation with satellite ground stations are not removed. SSGS argues that the advantages to placing a satellite ground station next to a data centre are already clear. It suggests that, for example, keeping the antenna systems physically close to compute and storage functions eliminates long terrestrial backhaul links and helps to reduce latency. Both the data centre and ground station can benefit from cost-savings and can become scalable digital hubs as capacity can be quickly added to meet increased demand. However, securing the necessary planning permissions, obtaining sufficient levels of funding, obtaining the necessary spectrum licenses in already crowded frequency bands, and event issues relating to data sovereignty can all hold up the process of colocation. Colocating data centres with satellite ground systems Kevin French, Director of the SSGS conference and exhibition, says, “Satellite ground systems are increasingly being colocated with data centres, and it’s not a coincidence; it’s a structural shift. "As demand for high-capacity, low-latency services accelerate, bringing ground infrastructure closer to compute isn’t just efficient; it’s transformative. “Colocation enables virtualised architectures, cloud native workflows, and far more resilient end-to-end operations. It ensures that satellite data isn’t just collected, but processed, stored, and delivered with the speed and reliability that modern networks now require.” While there are successful colocation projects in operation - such as the recent approval given to Amazon's Project Kuiper to operate a satellite earth station gateway at the National Space Centre (NSC) in Cork, Ireland - there are fears that the speed of approvals in some jurisdictions could lag behind demand and create a two-tier system. The issue of colocation, data centres, cloud, and edge computing is set to be a major topic of discussion at the SSGS conference being held at the Park Plaza Hotel in London on 30 September 2026.

Keysight expands validation for 1.6T AI DC interconnects

Keysight Technologies, a manufacturer of electronic test and measurement equipment and software, has introduced the Functional Interconnect Test Solutions (FITS) portfolio, alongside the first product in the range, FITS-8CH, designed to validate digital-layer error performance for high-speed optical and copper interconnects used in network infrastructure. The platform provides bit error ratio (BER) and forward error correction (FEC) validation for interconnect technologies supporting modern ethernet architectures, including 400GE, 800GE, and emerging 1.6T deployments. As interconnect speeds increase and designs become more complex, manufacturers of chips, interconnects, and networking equipment face greater pressure to ensure reliability before mass production and during manufacturing. While traditional physical-layer test tools validate electrical lanes against industry specifications, system-level testing provides additional insight into how fully integrated interconnect assemblies perform under operational conditions. Digital-layer testing for high-speed interconnects The FITS-8CH platform provides multi-lane error performance validation at the digital layer, supporting PAM4 signalling speeds from 53Gb/s to 212.5Gb/s. The system enables simultaneous bi-directional testing across eight transmit and eight receive channels, allowing complete optical or copper interconnect assemblies to be validated during development, manufacturing, and system-level qualification. The platform also integrates with Keysight’s physical-layer testing systems, enabling validation across a broader range of network configurations and topologies. According to the company, the platform includes automated lane-by-lane tuning to optimise PAM4 signal output and improve measurement consistency. This capability can help identify potential manufacturing or configuration issues earlier in the process, including mechanical misalignment, thermal failures, or incorrect digital signal processor settings. Keysight says the FITS portfolio is intended to support testing requirements across the full product lifecycle, from research and development through to production and deployment in large-scale network environments.
