Converts single PCIe x16 slot to two SFF-8654 ports for 4-slot expansion.
The LRFCF944-X4 is a high-performance PCIe expansion solution designed to maximize connectivity in servers and workstations. By converting a single PCIe x16 slot into two SFF-8654 (SlimSAS) interfaces, it enables the connection of additional PCIe devices through expansion cards.
Each SFF-8654 port supports PCIe 4.0 x4 signaling, allowing for a total of four downstream PCIe x4 slots when used with compatible breakout cables or backplanes. This makes it ideal for applications requiring high-density PCIe lane distribution without consuming multiple motherboard slots.
The card features a robust hardware design with a dedicated SATA 8-pin power connector to ensure stable operation under load. It is built to withstand industrial environments with an operating temperature range of 0°C to 70°C, making it suitable for data centers, cloud storage, and industrial automation systems.
Features two SlimSAS 4i sockets (SFF-8654) supporting PCIe 4.0 x4 signaling each.
Utilizes PCIe 4.0 standard for high-speed data transmission between host and devices.
Converts one PCIe x16 slot into four PCIe x4 lanes via two SFF-8654 connectors.
Equipped with a standard SATA 8-pin power connector for stable output and expansion.
