Japanese firms lead global standardization of All-Photonics networks.

Japanese firms lead global standardization of All-Photonics networks. Several major Japanese telecommunications companies have successfully secured international recognition for a new framework designed to support low-latency and energy-efficient networks in the AI era. The framework, developed by KDDI Corporation, NTT, Inc., 1Finity Inc., NEC Corporation, Rakuten Mobile, Inc., Oki Electric Industry Co., Ltd., and Sumitomo Electric Industries, Ltd., was approved as an international standard by the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) on August 13, 2026. This framework is a significant step towards realizing the All-Photonics Network (APN), a key component of Japan's strategy for next-generation information and communication infrastructure. The APN aims to provide high-capacity, low-latency, and energy-efficient communications, facilitating real-time data processing from remote sensors and robots. The IOWN Global Forum, an organization focused on promoting APN-based next-generation communication infrastructure, is currently developing technical documents on APN architecture and functional requirements. Concurrently, research on photonic network federation technology, which ensures stable interconnection among APNs from different providers, is progressing. This research is crucial for developing interconnection methods and evaluating them with actual equipment. Despite the progress, achieving global interoperability and adoption of the APN framework requires broad international consensus. To address this, Japanese telecommunications operators and equipment manufacturers have spearheaded the development of this standardized framework, now known as Recommendation ITU-T Y.3335. This framework outlines network configurations and technical requirements for low-latency, energy-efficient communication paths across different operators. The ITU-T's approval provides a universal framework for APN, facilitating the creation of APN services that span multiple operators and offer high-speed, energy-efficient communication services across geographically distributed sites. The seven companies involved will continue to promote standardization activities both in Japan and internationally, leveraging the network technologies and expertise developed in Japan. Within ITU-T, these companies are also contributing to the development of a recommendation on the functional architecture for low-latency and energy-efficient networks, expected by October 2028. Their ongoing efforts aim to support the global adoption of APN, aligning with the demands of the AI era.

AFL, Corning, Sumitomo and TeraHop set four-core fibre MSA.

AFL, Corning, Sumitomo and TeraHop set four-core fibre MSA. August 12, 2026 AFL, Corning Incorporated, Sumitomo Electric Industries and TeraHop have formed a multi-source agreement (MSA) to establish common specifications for four-core multicore fibre in AI data-centre applications. Called the SDM4 MCF MSA, the initiative will define the fibre's design, performance and interoperability requirements, with an initial focus on passive optical connections. The companies plan to release the first specification publicly in the coming months. The move addresses growing demand for higher-density optical infrastructure as hyperscalers scale out AI clusters. Multicore fibre can carry more connectivity within the same physical footprint than conventional single-core fibre, offering a potential path to higher capacity in constrained data-centre environments. The MSA will cover intra-campus networks and other short-reach interconnects operating in the O-band, typically centred around 1310 nm. It is also intended to provide a technical base for wider standards development at bodies including the ITU-T, IEC and IEEE. An MSA is an industry-led, multi-vendor technical framework designed to ensure that components from different suppliers can work together. The four companies said additional participants would be invited after the initial specification is released, supporting the broader multicore-fibre ecosystem and market adoption. The consortium's formation signals an effort to move multicore fibre from proprietary deployments toward interoperable, multi-supplier infrastructure for AI data centres. CT Bureau

Error-proofing 2,000 parts in Automotive Assembly.

Error-proofing 2,000 parts in Automotive Assembly. Published by: Joyce Yeung HJI Supply Chain Solutions, a trusted Tier 1 and Tier 2 automotive supplier, partners with industry leaders like Ford Motor Company, Yanfeng, and Sumitomo. As a multi-generational business and a Black and woman-owned company, HJI is committed to quality, diversity, and operational excellence in automotive manufacturing. Recently, HJI secured a major contract to supply replacement headliners for a Tier 1 automotive OEM. With over 30 manual assembly steps and significant variations per car model, ensuring consistent quality at scale was a challenge. To streamline operations, reduce errors, and improve traceability, HJI implemented PICO for comprehensive error-proofing to eliminate common human mistakes found in automotive manufacturing. By leveraging poka-yoke in manufacturing, HJI improved production efficiency, minimized defects, and strengthened its ability to meet automotive compliance standards - paving the way for long-term business growth in the competitive auto supplier industry. Operators at HJI Supply Chain Solutions rely on digital worker guidance to deliver step-by-step instructions in assembly. Operators building headliners at HJI's facility Operator takes pictures of final assembly for quality assurance Images can be attached to final build report in PICO Challenges in Automotive Assembly Complex Manual Assembly with High Variability The assembly of automotive headliners is a multi-step manual process requiring precision. For just one car model, there are over 20-30 variations, each requiring unique assembly steps. "This wasn't a commodity our team had experience building. We had to learn from scratch and train new operators quickly," explains Maurice Stallard, Director of Engineering and Manufacturing at HJI. Traditional training methods - paper-based instructions or tribal knowledge - weren't sufficient for scaling operations or ensuring consistent quality. Without an error-proofing system, mistakes were inevitable, putting customer contracts at risk. High Risk of Part Number Errors Tracking part numbers manually - especially those over 10 digits long - led to costly mix-ups in previous supply chains. Incorrect parts were installed on finished goods, causing delays, rework, and potential compliance violations. "We knew we didn't want to track everything in a binder anymore. We needed a system that could eliminate errors at the source," says Stallard. Without automated traceability and digital part verification, errors could slip through unnoticed, impacting Tier 1 supplier quality metrics and customer confidence. [Left] A headliner is a material that covers the ceiling of a vehicle, but it does more than hide bare metal with color-coordinated soft fabric. Headliners provide insulation against heat and noise, and they can also hide wiring and hardware for electrical components, antennas, and other accessories. [Right] A fully assembled headliner Meeting OEM Quality Standards and Improving Product Quality HJI adopted PICO for error-proofing, digital work instructions and real-time manufacturing track and trace to meet the high-quality standards required in automotive manufacturing. Error-Proofed Work Instructions for Automotive Assembly * Operators use digital work instructions on a tablet with step-by-step worker guidance. * The system automatically verifies each step, preventing mistakes before they happen. * Instructions include precise timing prompts, such as "Apply sealant and hold for 10 seconds", ensuring correct execution. Digital Traceability * Every headliner component is scanned and assigned a unique serial number, allowing full traceability from operator to workstation to shipment. * Operators can attach images and notes to each assembly, providing quality assurance transparency for both HJI and its automotive OEM customers. * The system flags mismatched or incorrect parts instantly, reducing costly errors. Standardized Training & Faster Onboarding * New operators can get up to speed faster with interactive digital worker guidance. * Standardized processes ensure consistent quality across all shifts. "Demonstrating automatic error-proofing capabilities is one of the reasons we won this large automotive contract. It helped alleviate a lot of initial concerns from our customer," said Stallard. Outcomes in Nine Months * Connected 12 workstations * Digitized 151 workflows * Expanded customer contracts from 2 to 14 models * Shipped 1,685 units, all error-free HJI has eliminated assembly errors, improved quality control, and ensured 100% part traceability, leading to fewer defects, reduced scrap, and higher customer satisfaction. HJI also feels confident in its robust traceability across its assembly lines. Every part is assigned a serial number which can be traced back to the exact operator, workstation, and parts. By easily tracking each part's journey, HJI has reduced scrap and rework. "We're hitting our quality metrics, ensuring that we deliver products our customers feel good about selling," said Stallard. Empowering the Supply Base for Successful Outcomes HJI overcame many common assembly and training challenges that helped solidify and grow its business. From preventing manufacturing mistakes to enhancing employee satisfaction and operational efficiency, PICO has become integral to HJI's operations. By implementing PICO, factories can streamline processes, enhance quality, boost employee satisfaction, and accelerate their growth - just as HJI has done.
