Keysight Technologies taps Credo Devices for 800GE testing

Sept. 6, 2022
New partnership will enable new line-rate testing equipment for network equipment OEMs, cloud service providers, hyperscale data centers and manufacturers of optical and copper interconnects.

Credo Technology Group Holding Ltd. (NASDAQ: CRDO) announced that Keysight has selected the Credo retimer/gearbox devices to drive the Keysight line of Layer 1-3 800 Gigabit Ethernet (GE) network device and Ethernet protocol test boxes for use in network infrastructure.

Keysight's platform provides comprehensive 800GE Layer 1-3 test coverage with an extensive set of use cases and break-out Ethernet port speeds from 800GE to 100GE, while maximizing on what the company claims is the highest port density per rackmount unit in such test solutions.

According to a press release, Keysight selected Credo for its second generation 800GE networking ICs based on customer demand for two strategic test capabilities:

  • First, the chip-to-module, high performance SERDES with 112 Gb/s electrical lanes with PAM4 signaling for 1x800GE and related slower port speed support.
  • Secondly and most importantly, the ability to provide auto negotiation and link training (AN/LT) – which Credo maintains is "a must-have for support of passive and active direct attached copper (DAC) cabling required for switch and server interconnections within equipment racks that are deployed in high volume within data centers."


“Keysight’s close collaboration with Credo enables us to provide the global networking industry a comprehensive set of test and measurement capabilities that address the rapidly growing and diverse ecosystem of 800GE-capable components, network silicon devices, and networking equipment systems. The critical aspect of the growth of the 800GE ecosystem is to assist manufacturers to develop and demonstrate the ability of all these devices to successfully interoperate.” -- Ram Periakaruppan, vice president and general manager, Keysight Network Test and Security Solutions

“In today’s data driven economy no business should gamble on data center performance, hence the need for differentiated equipment testing solutions that provide end-to-end validation of network infrastructure. It’s an honor to work with a trusted industry leader like Keysight to enable data center operators to validate 800GE devices in complex environments constrained by space, capacity and power.” -- Scott Feller, vice president of marketing, Credo
