LRES4004TF-POE is a PCIExpress x1 dual-port optoelectronic hybrid PoE+Gigabit Ethernet frame capture card independently developed by Shenzhen Lianrui Electronics Co., Ltd. based on the Intel main control solution. It is compatible with PCle x8 and x16 channels. This server adapter card is mainly designed to be used in industrial field visual inspection servers and equipment, visual field clients, fast mobile Ethernet data transmission equipment and other occasions that require simultaneous optical fiber transmission, and is also suitable for ordinary servers. At the same time, the LRES4004TF-POE allows a PC to power a VolP phone or any other traditional copper powered device over the network.
The adapter has integrated hardware acceleration and is capable of performing TCP/UDP/IP checksum offload and TCP segmentation tasks. The host processing technology can offload the accelerator, and the host processing technology can offload the accelerator to release the occupation of CPU resources to free up more CPU resources to process other applications.
LRES4004TF-POE is developed on the Intel dual-port Ethernet MAC+PHY (media access controller and physical interface transceiver) controller. The Gigabit POE working channel and the Gigabit fiber working channel are mutually compatible, and can be used in different requirements. Use different fiber optic modules for flexible use. At the same time, the bandwidth can be expanded through link aggregation, which can save PCI Express channel resources without occupying the bus bandwidth.
