Insights
With the surge in AI and ML applications, there's a corresponding increase in data traffic within data centers. This necessitates a shift towards higher bandwidth solutions that can handle the upsurge efficiently. The introduction of 100Gbit/s PAM4 single-mode VCSEL technology by Adtran is a pivotal development in this space. By achieving speeds up to 1.6Tbit/s, Adtran is addressing the bandwidth bottleneck that could otherwise hinder the performance of data-intensive applications.
VCSEL technology has been a game-changer for short-reach optical communications due to its low cost and high performance. The transition to single-mode VCSELs from the multimode variant is significant as it allows for longer reach and higher data rates, which are essential for intra-data center connectivity. Moreover, the energy efficiency achieved, with an 80% power savings and sub-2pJ/bit consumption, is critical for sustainable growth in the industry. This technology not only reduces operational costs but also aligns with the global push towards greener technologies.
The operational impact of Adtran's new VCSEL technology on data centers is substantial. As data centers evolve to support more complex and data-heavy AI/ML workloads, the need for high-capacity, energy-efficient interconnects becomes more pronounced. Adtran's innovation directly addresses this need by providing a scalable solution that can support the current and future demands of AI applications.
The versatility of this technology in supporting a wide range of applications, from DR4/8/16 to FR4 links, means that data center operators can integrate it into existing infrastructures with minimal disruption. The reduced power consumption per lane also translates into lower cooling requirements, further diminishing the total cost of ownership (TCO) for data center operators. This technological advancement is likely to set a new industry standard for optical interconnects within data centers, influencing future design and operational strategies.
From an environmental sustainability standpoint, the advancements presented by Adtran are noteworthy. The significant reduction in power consumption by up to 80% is a testament to the industry's ability to innovate with an eye towards reducing carbon footprints. The energy efficiency of this technology is particularly important as the digital infrastructure industry is under increasing pressure to mitigate its environmental impact.
By setting a new benchmark for low power consumption, Adtran is not only providing a competitive edge but also contributing to the broader sustainability goals of the tech industry. The long-term implications of such advancements could be profound, encouraging the adoption of similar technologies across the sector and potentially influencing regulatory standards on energy consumption for data centers.

“As the importance of data volume and speed escalates, the demand for increased bandwidth and enhanced energy efficiency accelerates. Our introduction of the market’s first 100Gbit/s PAM4 single-mode VCSEL technology, scalable to 1.6Tbit/s, epitomizes our proactive approach to tackling these emerging requirements. By pushing the limits of speed and significantly reducing power consumption, we’re creating tomorrow’s benchmarks,” said Ross Saunders, GM of optical engines at Adtran. “Our new technology promises to significantly improve intra-data center connectivity and AI application efficiencies, merging high performance with long-term sustainability. As we prepare for the leap towards 800Gbit/s and 1.6Tbit/s applications, we’re enhancing the foundations of efficient, high-capacity data ecosystems worldwide.”
Building on the success of Adtran’s MicroMux™ family, the new VCSEL technology leverages a short-cavity single-mode design and is based on indium phosphide semiconductor material. This enables it to operate across both O-band and C-band wavelengths, delivering 100Gbit/s per channel. By stacking multiple single-mode lasers into arrays, this approach achieves throughput of 800Gbit/s and 1.6Tbit/s, ensuring superior performance with a significant reduction in power consumption and costs. This enhanced energy efficiency presents a major advantage for IP router and Ethernet switch faceplate density. What’s more, its versatility extends to supporting a wide array of applications from DR4/8/16 to various FR4 links within optical engines, all while maintaining power consumption below 200mW per lane.
“As applications such as generative AI proliferate and enterprises expand their AI clusters, the need for advanced optical interconnects capable of supporting Terabit connectivity has reached a critical juncture. Our 100Gbit/s PAM4 single-mode VCSEL technology meets this challenge head-on. It enables energy efficiency and the capacity for higher-density deployments while at the same time addressing manufacturing, testing and assembly costs,” commented Christoph Glingener, CTO of Adtran. “This technology supports throughput of up to 800Gbit/s and 1.6Tbit/s, significantly reducing operational expenses while enhancing network capabilities. Our approach underscores a commitment to delivering sustainable, high-capacity networking solutions that break through existing barriers, readying networks for the next wave of AI infrastructure development.”
