New Nova 2 PAM4 optical DSP enables greater
performance and bandwidth density to optimize AI and cloud
infrastructure
SANTA
CLARA, Calif., March 25,
2024 /PRNewswire/ -- Marvell Technology, Inc.
(NASDAQ: MRVL), a leader in data infrastructure semiconductor
solutions, today announced Marvell® Nova 2, the
industry's first 1.6 Tbps PAM4 optical DSP featuring 200 Gbps
electrical and optical interfaces to meet the escalating
performance demands of accelerated infrastructure, generative AI,
and high-performance computing.
Marvell also announced that the flagship Nova optical DSP, a 1.6
Tbps device with 100 Gbps electrical and 200 Gbps optical
interfaces announced last year, is now generally available. It will
be showcased at the Marvell Booth (#2225) at OFC 2024 taking place
this week in San Diego,
California.
A breakthrough in optical connectivity technology, 1.6T Nova
optical DSPs enable module manufacturers to develop a wide range of
industry-standard form factor optical modules that deliver 2x more
bandwidth than current 800 Gbps optical modules for the transition
to 200G interfaces in accelerated infrastructure. Doubling optical
module and interface bandwidth greatly increases the amount of
network traffic that can be managed within the same physical space,
thereby paving a pathway to scale capacity and increase return on
infrastructure investments.
"200 Gbps signaling will be a defining feature for the next wave
of AI clusters and cloud data centers and provide the performance
needed to deliver services based on generative AI and large
language models," said Xi Wang,
Ph.D., vice president of product marketing for Optical Connectivity
at Marvell. "The latest advancements in our Nova product family
extend our longstanding leadership in PAM4 optical DSP technology
to advance the industry towards next-generation cloud data center
architectures."
Optical Technology for Accelerating Infrastructure
The
intensive bandwidth and performance demands of AI and cloud
workloads are fundamentally transforming, and accelerating, data
infrastructure architectures. Bandwidth capacity in the cloud,
measured by Ethernet ports shipped, continues to increase at over
50% per year while bandwidth for AI applications is growing at over
100% per year1.
Optical DSP technology is critical for assuring signal integrity
in high-speed, large and complex optical networks. The increasing
need for greater connectivity bandwidth, the increasing size of AI
clusters and cloud data centers, and the greater distances between
nodes mean that optical DSPs are becoming more pervasive and more
performant.
"Networking and connectivity are the linchpin for AI," said
Alan Weckel, co-founder of 650
Group. "We are seeing increased focus on the performance of
switches and optical modules by hyperscale cloud providers because
they understand that networking performance is absolutely vital to
the success of these new services. Nova 2 is the latest milestone
for Marvell and the industry."
The Nova family leverages four generations of proven industry
leading PAM4 optical DSP technology from Marvell. Newly
announced Nova 2 features eight 200 Gbps electrical lanes to the
host device and eight 200 Gbps optical lanes to interface with a
wide range of optical components to enable 1.6T total bandwidth
that can fit inside standardized module form factors utilizing
eight electrical lanes. Nova 2 based optical modules support
backward compatibility for up to three generations. Nova 2 is
designed for next-generation AI networking fabric infrastructure
where switches, network interface cards (NIC), and accelerators
will be based with 200 Gbps I/O interfaces. The first flagship Nova
device is designed for connecting devices based with 100 Gbps
electrical I/O interfaces, used in clouds today.
"Marvell is once again bringing an industry-first 1.6T optical
DSP to the pluggable optics ecosystem and delivering the
connectivity speed needed to tackle the most demanding AI
workloads," said Osa Mok, chief
marketing officer, InnoLight Technology. "The Marvell Nova 2 DSP,
combined with InnoLight's high-speed optical transceiver design and
manufacturing capabilities, brings to the industry a
state-of-the-art pluggable module for doubling bandwidth capacity
for the growing performance requirements of data center
infrastructure."
Key features of the Nova 2 electro-optics platform include:
- 200 Gbps per lane line-side transmitter interface supporting a
wide range of high-speed lasers
- 200 Gbps per lane line-side receiver with companion Marvell
TIAs, providing best-in-class linearity and low noise
- Integrated laser drivers, optimizing power dissipation and
transmit performance
- Latency-optimized FEC for 200 Gbps traffic
Availability
The Marvell 1.6T Nova 2 optical DSP with
200 Gbps electrical and optical interfaces is sampling in the
second quarter of 2024 to select customers. The Marvell 1.6T Nova
optical DSP with 100 Gbps electrical and 200 Gbps optical
interfaces is generally available.
