Continuing external communicationPCIe 7.0 specification development directionIn addition, PCI-SIG earlier announced the establishment of a new working group to discuss how to connect PCI Express (PCIe) technical specifications optically to expand the scope of application of PCI Express technical specifications.
PCI-SIG President and Chairman Al Yanes stated that optical connections are already widely used in the industry to transmit data. Further integrating this connection method with the PCI Express technical specification will enable more diverse and widely deployed usage models.
Compared to traditional PCI Express technology specification applications that rely on wired and circuit connections, Insight 64 researcher Nathan Brookwood anticipates that optical connections will become a significant advancement in PCI Express technology applications. These connections will enable higher data transmission efficiency, operate with lower power consumption, and provide wider transmission coverage, while also reducing overall transmission latency. He even believes that cloud deployments, quantum computing, and hyperscale data centers will all adopt PCI Express technology specification architectures based on optical connections.
The new working group announced this time will discuss how to connect PCI Express specifications optically. PCI-SIG's current focus will remain on promoting the PCIe 7.0 specification, aiming to reach a bit transfer rate of 128 GT/s and a bidirectional bit transfer rate of 16 GB/s in a x512 configuration.
