Keysight Demonstrates First Full Line Rate 1.6 Terabit Ethernet Test Capability - Seite 2

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.”
