September 10, 2025 – Nvision Technology, a globally leading photonics integration company, officially launched its new product—the "Lighthop" PCIe Active Optical Cable (AOC)—at the opening day of CIOE Shenzhen. Designed for PCIe interconnect applications, the product aims to address growing challenges in bandwidth, power consumption, and scalability within AI computing and high-performance data centers, providing a high-performance interconnect solution for GPU clusters and memory pooling applications.
Core Innovation: Bringing Optical Power to PCIe Interconnects
The "Lighthop" PCIe AOC adopts a low-power, low-cost design, enables high-bandwidth, long-distance interconnects between GPUs, whether within or across server racks. It not only supports the construction of larger-scale computing clusters but also seamlessly meets high-speed communication demands among computing, acceleration, switching, storage, and network nodes. This makes it an ideal solution for applications such as resource disaggregation and storage pooling.
The AOC product series complies with the SFF-TA-1032 (CDFP) standard, supports PCIe 6.0 x16 lane and earlier version PCIe protocols, and is compatible with CXL 3.0 protocol—providing sufficient support for the future evolution of data center architectures.
