Marvell to Demonstrate Industry's First 400G/lane PAM4 Electrical-to-Optical Link Technology at OFC 2025
Marvell® 400G Technology is an Industry Breakthrough Enabling a New Generation of PAM4 Network Connectivity SANTA CLARA, Calif., March 31, 2025 /PRNewswire/ -- Marvell Technology, Inc. (NASDAQ: MRVL), a leader in data infrastructure semiconductor solutions, will demonstrate the industry's first 400G/lane technology with complete electrical to optical link operating at 224 Gbaud at OFC 2025 taking place March 30-April 3, 2025 in San Francisco, CA. This technology was once considered impossible, but Marvell has now proven it in real silicon. Marvell is also working with leading optical and switch companies to cultivate an ecosystem to develop products based on 400G/lane technology for AI and general-purpose cloud architectures. Marvell (booth #2129), Lumentum (booth #2119) and TeraHop (booth #2429) will showcase live demonstrations of the 400G technology for both optical and electrical applications at the conference. The demonstrations include PAM4 DSP, transimpedance amplifiers, modulator drivers, and photonics technologies developed for serial 400G/lane speed with PAM4 modulation. 400G/lane technology will enable cloud data centers to significantly increase bandwidth capacity across their infrastructure, maximize output, enhance the efficiency of future data centers and shorten the time required for AI training and other complex tasks. 400G/lane technology represents a 4x increase over the mainstream 100G/lane infrastructure in cloud and AI data centers today and a 2x increase over the 200G/lane infrastructure being deployed in the industry this year. 'Pluggable transceiver modules will remain the dominant solution for optical connectivity in data centers and other infrastructure through 2030,' said Dr. Lee Xu, Executive Vice President and General Manager, Datacom Business Unit at Coherent. 'Our collaboration with Marvell and the rest of the ecosystem will help ensure that our customers will have the fabric technology they need to deliver on the promise of AI.' 'This demonstration clearly illustrates how Lumentum and Marvell are driving industry leadership and readiness in 400G per lane technology,' said Matt Sysak, CTO of Cloud and Networking at Lumentum. 'The next generation of 3.2T transceivers required for AI/ML and cloud infrastructure scale-out will benefit significantly from Lumentum's advanced high-speed InP technology, enabling unmatched performance and volume scalability.' 'Networking takes an ecosystem. Through efforts like this, we can lay a foundation for the AI economy and continue to expand the opportunity for optics in infrastructure,' said Osa Mok, Chief Marketing Officer, Terahop PTE Ltd. 'Marvell has a long history of innovation in PAM4 connectivity, being the first to demonstrate proven 100G/lane and 200G/lane, and now 400G/lane PAM4 connectivity, ushering in an entirely new generation of network connectivity for the future,' said Xi Wang, vice president and general manager, Connectivity Business Unit at Marvell. 'We're excited to be working with leading partners like Coherent, Lumentum, and TeraHop to forge a roadmap for the next chapter in networking.'

Keysight and Coherent Revolutionize Data Transfer and Network Efficiency with 200G/lane Multimode VCSEL Technology at OFC 2025
Collaboration enables 200G characterization, tuning, and validation of the powerful new VCSEL technology Increased bandwidth of 200 Gbps/lane doubles data throughput of the current highest speed multimode interconnects More efficient and cost-effective technology compared to single-mode transmission SANTA ROSA, Calif., March 27, 2025--(BUSINESS WIRE)--Keysight Technologies, Inc. (NYSE: KEYS) and Coherent Corp. collaborated on a 200G multimode technology demonstration that will be showcased for the first time at OFC, in San Francisco, California. The 200G per lane vertical-cavity surface-emitting laser (VCSEL) technology provides higher data transfer rates and addresses industry demand for higher bandwidth in data centers. It will enable the industry to deliver AI/ML services while reducing power consumption and capital expense of short-reach data interconnects. AI/ML deployment is driving extreme growth in the amount of data transfer in data centers. The cost of optical interconnects is an ever-growing portion of the Capex of the data center, while the power consumption of the optical interconnects is an ever-growing portion of Opex. 200G multimode VCSELs revolutionize data transfer and network efficiency, offering the following benefits compared to single-mode transmission: Increased Bandwidth: 200 Gbps/lane doubles the data throughput of the current highest speed multimode interconnects. Power Efficiency: Significantly lower power-per-bit relative to single-mode alternatives driving down electrical power operational expense and helping large-scale data centers minimize their environmental impact. Cost Efficiency: Multimode VCSELs are less costly to manufacture than single-mode technologies, providing lower capital outlay for short-reach data links. Compatible Network Architecture: AI pods and clusters require many high-speed, short-reach interconnects to share data amongst GPUs, aligning well with the strength of 200G multimode VCSELs. The 200G multimode demonstration consists of Keysight's new wideband multimode sampling oscilloscope technology, Keysight's M8199B 256 GSa/s Arbitrary Waveform Generator (AWG) and Coherent's 200G multimode VCSEL. The M8199B AWG drives a 106.25 GBaud PAM4 electrical signal into the Coherent VCSEL, and the PAM4 optical signal output from the VCSEL is measured on wideband multimode scope displaying the eye diagram. The demo showcases the feasibility and capability of Coherent's new VCSEL technology as well as Keysight's ability to characterize and validate this technology. Lee Xu, Executive Vice President and General Manager, Datacom Business Unit at Coherent, said: "Keysight has been a trusted partner and a leader in test instrumentation technology, providing advanced test solutions to us. We rely on Keysight products, such as the M8199B Arbitrary Waveform Generator, to validate our latest transceiver designs. We look forward to continuing our collaboration as we push the boundaries of optical communications with products based on 200G VCSEL, silicon photonics, and Electro-Absorption Modulated Laser (EML)." Dr. Joachim Peerlings, Vice President and General Manager of Keysight's Network and Data Center Solutions Group, said: "We are pleased with the progress the industry is making in bringing 200G multimode technology to market. Our close collaboration with Coherent enabled another milestone in high-speed connectivity. The industry will benefit from a more efficient and cost-effective technology to address their business-critical AI/ML infrastructure deployment in the data center."
