30 PRODUCT UPDATE Issue 3 2024 Power Electronics Europe www.power-mag.com Molex, a global electronics leader and connectivity innovator, has announced it has introduced a thermal management solution that reduces the time and cost of deploying and upgrading high-performance data centres to meet unrelenting demand for generative AI and machine learning workflows. The company says Molex VaporConnect Optical Feedthrough Modules for two-phase immersion cooling address constant increases in data centre speed and capacity by leveraging a unique, cassette-based design that bolts directly onto immersion tanks and enables optical transceivers and network cabling infrastructure to be swapped out without changing mechanical interfaces or impacting immersion tank architecture. Reference designs for the new modules will be available commercially in Q1 of 2025. “Molex continually embraces innovative optical solutions to ease data center deployments and upgrades while alleviating critical thermal management challenges,” said Trevor Smith, General Manager, Optical Connectivity, Molex. “VaporConnect gives customers the flexibility to upgrade connectivity and scale cooling system designs to keep pace with data center growth by simply deploying a different module, which will accelerate upgrades while reducing overall energy, cooling and technology costs.” Streamlining Two-Phase Immersion Cooling Molex VaporConnect Optical Feedthrough Modules simplify the connections between optical transceivers contained within immersion tanks and cabling infrastructure that exists outside the tank using fully upgradeable sealed modules. With VaporConnect, sealing and cabling is accomplished inside the module, giving customers the opportunity to upgrade connectors without impacting immersion tank design or architecture. Additionally, customers have the flexibility to re-use standard cabling infrastructure for multiple product generations, which further reduces deployment time, cost and complexity. A full range of industry-standard and Molex optical connector form factors are available for single- and multi-mode fibre solutions. They also feature mixand-match functionality to facilitate system upgrades to newer or denser connectors. Customizable module footprints are available to fit specific space and application requirements. Also, Molex VaporConnect Optical Feedthrough Modules are designed to minimise external patching and shuffle requirements by leveraging Molex FlexPlane optical circuitry technology. As a result, complex optical shuffles and high-density fibre routing are integrated seamlessly within the module for simpler installation and plug-and-play operation. Reliable, Versatile, Upgradeable Optical Interconnects A sealing gasket comes with every VaporConnect module, which is thoroughly tested using industry-standard, helium-leak testing to ensure a reliable seal with the tank wall. This also assures a seamless transition from the server line cards inside the tank to outside cabling infrastructure. Testing is underway for compliance with industry-standard GR-1435-CORE. VaporConnect modules are designed to accommodate customer specifications, with the number of fibre channels dependent on the number and type of connectors used. As many as 576 fibres can be integrated into a single module. A range of form factor options are available, including MPO, LC and very small form factor (VSFF) options, such as MMC, MDC, SN and SNMT. This ensures conformance to existing infrastructure and streamlines system upgrades. As part of Molex’s continued investment in this area, an EBO connector option is currently in development, with availability slated for the first half of 2025. Commitment to Optical Network Innovations on Display at ECOC 2024 As one of the largest manufacturer of Optical Feedthrough Modules for twophase immersion cooling, Molex says it has shipped more than 350,000 optical channels to date. At this year’s ECOC’24, Molex says it will reinforce its commitment to optical network infrastructure innovations with on-site product displays, including the new VaporConnect Optical Feedthrough Modules. The company’s extensive line of optical connectivity products, optoelectronics solutions and wavelength management systems also are being featured at Stand C75. As a participating member in OIF, Molex is part of an interoperability demonstration, which takes place at Booth B83, to spotlight optical networking innovations and solutions for data centres, AI/ML technologies and disaggregated systems. Molex Unveils Versatile VaporConnect Optical Feedthrough Modules Enabling Thermal Management Innovations to Address AI-Driven Data Centre Growth Bourns, a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions has announced it has introduced a new AEC-Q200 compliant, automotive grade, low profile, high creepage isolation transformer. The Bourns Model HVMA03F4A-LP8S Series flyback transformer is designed to support high power density for greater efficiency in a compact form factor. These capabilities are required in a wide range of applications, including gate drive and high voltage battery management systems (BMS). The company says this new flyback transformer series expands its portfolio of low power, high creepage isolation transformers. This series operates from a typical 12 V supply with an extended input voltage range of 10 to 24 V, and features a new coil mechanical design that helps to increase system performance and safety. These features are said to make the Model HVMA03F4A-LP8S Series ideal for use with Silicon Carbide (SiC), IGBT and Gallium Nitride (GaN) switching elements in automotive, industrial, and energy storage applications. The Model HVMA03F4A-LP8S Series is constructed with a centre-tapped output to generate a ±5 V supply to aid in biasing gate drive turn on and off circuitry. This new series is AEC-Q200 compliant and uses a basic insulation layer that complies with the IEC 60664-1 standard with a working voltage up to 800 VDC. It also features an 8 mm creepage and 2 mm clearance with a Hi-Pot isolation voltage up to 2750 VAC with an extended operating temperature range of -40 to 125 °C.
