Technologies and Products

Spirent Communications plc says it has supported H3C in successfully completing the industry’s first large-scale high-density 800G Ethernet test with up to 64 800G ports. The test results validated the reliability and high performance of H3C S9827, H3C’s 800G CPO silicon photonic switch series .

The company says this recent test leveraged the industry’s first high-density 800G OSFP and QSFP-DD test platform, the Spirent TestCentre 800G B2 Appliance. The B2 accelerates time-to-market for 800G infrastructure development and adoption, regardless of the interconnect strategy, providing customers the flexibility to use a test platform native to their actual network deployments. Supporting multi-rate interconnection with switches via cables, optical fibres and other interconnects, the B2 enables testing based on benchmark performance and scale standards.

The H3C S9827 series is a new generation of 800G data centre switches based on CPO silicon photonics technology, and test results showed a total switching capacity of up to 51.2T, with all 64 ports achieving 100% line speed forwarding under different traffic. Each port transmission rate reached 800Gbps, and the integrated CPO silicon photonics technology fully met the high throughput demands for intelligent computing networking, ensuring its suitability for AIGC clusters and other high-performance data centre core switching and related applications, which will help to unleash optimal computing power in the AIGC era.

“We were pleased to support H3C in verifying multiple breakthrough technology solutions for 800G Ethernet,” said Andrew Liu, VP of Sales for Spirent in Greater China. “We have developed a comprehensive, end-to-end 800G testing suite that leverages decades of experience in Ethernet testing. This latest positive 800G test validating the reliability and high performance of H3C S9827, H3C’s 800G CPO silicon photonic switch series, will help ensure successful deployments of this complex new technology and reliable high-speed networks to meet future demand.”

“The 800G high-performance switch, bolstered by CPO technology, will provide higher network capacity for cutting-edge applications such as AIGC and large-scale model training, paving the way for further improvement in the scale and computing power of computing clusters,” said Yutao Li, vice president of Network Product Line and general manager of Switch Product Line at H3C. “This joint test fully reflects H3C’s leading technical strength in the field of digital infrastructure. In the future, H3C will also help customers from various industries to comprehensively boost Ethernet performance, unleashing the full potential of computing power.”
