New solution enables 400GE tester to validate
legacy 100GE devices and networks
Keysight Technologies, Inc. (NYSE: KEYS), a leading technology
company that helps enterprises, service providers and governments
accelerate innovation to connect and secure the world, announced
the first, cost-effective test solution that enables data center
operators to leverage 400 Gigabit Ethernet (GE) capable test ports
to link with and test legacy 100GE network equipment.
The new test solution is comprised of Keysight’s Ixia AresONE
400GE High Performance Layer 1 through 3 test system based on Pulse
Amplitude Modulation level-4 (PAM4) signaling interconnected to
legacy 100GE non-return-to-zero (NRZ) networking equipment ports
using Credo’s HiWire™ Active Electrical Cable (AEC) technology.
This collaboration provides speed-shifting of the signaling rates
and forward error correction (FEC) conversion.
Data center operators have widely deployed mature 100GE
NRZ-based technologies. However, higher speeds, such as 400GE,
create a new mixed signaling, mixed FEC, multi-rate environment.
This new environment produces unique challenges relating to the
integration of PAM-4-based 400GE and 100GE-capable switch ports
with existing 100GE NRZ signaling-based switch port technology.
The combined Keysight and Credo test solution bridges the
signaling gap between incompatible PAM4- and NRZ-encoded signaling.
It removes potential compromises in testing configurations to
improve overall performance validation and quality. The AEC cable
technology performs the necessary conversions to allow a
PAM4-encoded port to interoperate with an NRZ-encoded port. The
solution provides support for testing four ports of 100GE NRZ from
a single port of 400GE QSFP-DD PAM4 in 4x100GE speed mode.
“Data center operators are faced with a complex environment and
need to leverage their existing investments for the future,” said
Ram Periakaruppan, vice president, product development, Keysight’s
Network Applications & Security group. “The Ixia AresONE 400GE
test system supports Credo’s interconnect technology in high
density 100GE test beds, enabling data center operators to
accelerate validation of 100GE NRZ devices and network
infrastructure while leveraging 400GE-capable PAM-4 ports to
support demand in the future.”
The combined solution features the Credo HiWire AEC which allows
flexibility in configuration of network rack equipment. Data center
operators can install 400GE-capable ports and connect them when and
where needed to legacy 100GE NRZ ports. Testing performed with the
Ixia AresONE 400GE combined with the Credo HiWire SERDES speed
shift and PAM4-to-NRZ conversion technology is completed at a
fraction of the cost of the equivalent configuration using optical
transceiver technology. Keysight and Credo are members of the
HiWire Consortium, a non-profit organization dedicated to
accelerating the adoption of AECs in applications such as this.
“Keysight’s Ixia AresONE 400GE test solution with 4x100GE per
port fan-out has the scale and performance to meet the verification
needs of multi-terabit Distributed Disaggregated Chassis networks,”
said Jeff Twombly, Vice President of Business Development at Credo.
“It is great to see them leverage our HiWire AEC interconnect
solution to deliver this industry-leading and innovative data
center solution.”
