- Industry’s first IEEE P802.3dj draft compliant 1.6 terabit
media access control engine developed by Keysight that can
generate, receive, and measure 1.6 terabits (1600GE) of full line
rate Ethernet layer 2 traffic
- Provides proof to the industry that a test and measurement
hardware development platform can test early 1.6 terabit
bandwidth-capable networking devices and interconnects.
- Real-world demonstration showcases Keysight’s innovation in
achieving another industry first for ultra high-speed Ethernet
traffic generation and measurement analysis
Keysight Technologies, Inc. (NYSE: KEYS) and Credo Semiconductor
(NASDAQ: CRDO) set a new milestone by developing a joint testbed
that demonstrates the first IEEE P802.3dj draft specification
compliant 1.6 terabit (T) Ethernet measurement system running full
line rate layer 2 Ethernet traffic on a real world hardware
development platform. This demonstration provides proof that 1.6T
Ethernet speed is possible and that its performance can be
measured.

Keysight co-developed the industry’s
first working 1.6 terabit Ethernet test and measurement system in a
testbed with Credo Semiconductor. Running at full line rate, it can
transmit and process more than a billion packets per second over a
2-meter active electrical cable – an unprecedented rate of speed.

Network bandwidth demand continues to grow 30-40% annually,
driven in large part by the need for today’s large-scale networks
to support data intensive technologies such as artificial
intelligence (AI), video streaming, cloud networking, and
high-performance computing. To keep pace, network equipment
manufacturers, silicon chip manufacturers, and data center
operators must build and operate next generation 1.6T Ethernet
networks.
To help data center operators overcome any potential hurdles,
network equipment and chip manufacturers must:
- Deliver higher speed and data throughput without increasing
data center power and cooling requirements
- Implement faster electrical lane speeds for the communication
chips embedded in optical transceivers, switches, routers, servers,
and test systems without compromising reliability or quality
- Measure the performance of silicon chips, network equipment,
and network interconnection devices during their quality assurance
(QA) cycle in final product benchmark testing
In recognizing the challenges of deploying 1.6T Ethernet,
Keysight, developed the industry’s first working 1.6T Layer 2
traffic generation and measurement system, and is demonstrating it
in a joint testbed with Credo. As 1.6T adoption gains momentum,
establishing a testing framework early in the product development
life cycle is critical to help speed time to market and enable
confident deployment. Keysight, a leader in 400GE and 800GE testing
is now helping companies prepare their 1.6T development plans and
has the measurement systems needed for early adopter testing.
Highlights of the Keysight and Credo testbed demonstration
include:
- Operational 1.6T Layer 2 engine – The engine operates on
an interface of 16 electrical lanes running at 106.25 gigabits per
second (Gbps) per lane with Pulse Amplitude Modulation 4 (PAM4)
signaling and Forward Error Correction (FEC). This is also called
16 x 100G SERDES.
- Keysight hardware development test platform –With
OSFP-XD front panel ports that can send and receive full line rate
1.6T layer 2 bi-directional traffic over a Credo provided 2-meter
HiWire Active Electrical Cable (AEC). The 1.6T measurement system
measures the performance of the link and the AEC.
- Reliability with FEC – The Layer 2 engine running at
full 1.6T line rate provides packet and FEC measurements, plus
counters, and other related statistics. FEC enhances data
reliability by detecting and correcting errors that occur during
data transmission. Manufacturers use these metrics during
development and quality assurance testing to identify areas for
improvement in device error correction performance and Ethernet
link stability over time. End users can utilize FEC measurements to
assess the resilience of network equipment under different stress
conditions, so they can confidently deploy devices, interconnects,
and networking equipment into their production networks.
Bill Brennan, Chief Executive Officer, Credo, said:
“Credo launched the 1.6T HiWire AEC in support of our key
customers’ product roadmaps in 2023 and it’s generated a great deal
of industry interest. We’re excited to work with Keysight to
support the buildout of a robust test and measurement ecosystem for
this developing networking standard.”
Alan Weckel, Co-Founder and Analyst, 650 Group, said:
“1.6T will be a critical speed to data center networking and key
technology to the adoption of future AI / ML deployments. The
Keysight 1.6T Ethernet Layer 2 traffic demonstration proves that
the industry is getting ready to support next-generation workloads
and move beyond 800 Gbps systems shipping now.”
Ram Periakaruppan, Vice President and General Manager,
Network Test & Security Solutions, Keysight, said: “1.6T
Ethernet is the next generation of Ethernet that addresses the
demand for more network bandwidth and data throughput, driven in
part, by ever-increasing AI workloads within the network
infrastructure. The 1.6T Ethernet Layer 2 traffic generation and
analysis demonstration moves the needle forward to enable
development of 1.6T devices and the entire networking equipment
ecosystem. Keysight’s Layer 2 and FEC test and measurement systems
are also vital to the success of the eventual deployment of 1.6T
capable networking devices and equipment.”
