LREM1000PF-2SFP+ is a PCI Express v3.0 x8 dual-port fiber 10G SFP + mezzanine Ethernet server adapter developed by Shenzhen Lianrui Electronics Co., Ltd. based on the SP1000A solution of the main controller Beijing NetXun Technology made in China. This server adapter is backward compatible with PCIev2.1 / v2.0 / v1.1. The theoretical throughput of the adapter card in a PCI Express v3.0 x8 slot is a single-port bidirectional transmission rate of 20GB, and a dual-port can achieve a bidirectional link rate of 40GB. It is suitable for use in firewalls, gateways, cipher machines, and other devices on security equipment platforms.

The Ethernet fiber network card (LREM1000PF-2SFP+) with independent intellectual property rights launched by Shenzhen Lianrui Electronics Co., Ltd. has many features such as LAN performance acceleration, network security, network convergence, network virtualization, data center bridging, etc. Function, the unidirectional transmission bandwidth of the single port is 10Gbps, the number of logic gates of the main controller reaches 18 million, the on-chip SRAM capacity reaches 25Mbit, and the PCIe v3.0 bus host interface is used.

The main controller used by the optical fiber network card has China's independent intellectual property rights and independent controllability, which is of great significance for breaking the monopoly and ensuring national information security.

The controller used by LREM1000PF-2SFP+ is Net-swift SP1000A, which is autonomous and controllable. There are major innovations in the layered DMA queue architecture, seamless switching of virtual machine hot migration networks and cross-slicing, and the overall technology has reached the international advanced level. Including the average transmission delay, the actual packet transmission rate and other indicators reached the highest level disclosed in the industry.
