News summary:
- Surge in AI/ML applications calls for unprecedented bandwidth
and enhanced energy efficiency in intra-data center
connectivity
- Adtran’s VCSEL arrays achieve 800Gbit/s and 1.6Tbit/s speeds
with transmit optics power savings of up to 80%
- Single-mode VCSEL technology will extend MicroMux™ family of
pluggable transceivers to support data-intensive compute
clusters
Adtran and Vertilas today announced the industry’s first
100Gbit/s PAM4 single-mode vertical-cavity surface-emitting laser
(VCSEL) technology with capabilities up to 1.6Tbit/s. On display at
this week’s OFC, it sets new standards for low power consumption in
optical engines and modules, with up to 80% reduction in power on
the transmit optics compared to conventional solutions. Tailored
specifically for the rigorous demands of intra-data center
operations and AI/ML workloads, Adtran’s latest offering achieves
unprecedented efficiency, consuming less than 2pJ/bit, including
the laser driver. This significantly undercuts current industry
standards, including those cited by co-packaged optics. The
advancement is set to extend the capabilities of Adtran’s MicroMux™
family of small-form-factor pluggable transceivers. A major step
towards meeting the needs of the rapidly expanding generative AI
application market, Adtran’s latest innovation addresses the
growing demand for robust, high-capacity and environmentally
friendly data processing solutions.
“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.”
Demos of Adtran’s new VCSEL technology are available at this
week’s OFC on request.
