It is compatible with the PCIe X8 and x16 channels. The design of the server adapter card is mainly used in industrial field visual inspection server and equipment, visual field client, fast mobile Ethernet data transmission equipment and other occasions that need optical fiber transmission at the same time, and it is also suitable for ordinary servers. At the same time, lres4004tf-poe allows personal computers to power VOIP phones or any other traditional copper powered device over the network. The adapter card has integrated hardware acceleration function, and can perform TCP / UDP / IP verification and load sharing and TCP segmentation tasks. The host processing technology can load the accelerator, and the host processing technology can split the accelerator to release the occupation of CPU resources, so as to free up more CPU resources to process other applications. The adapter card is an ideal solution for deploying multiple networks and deploying critical network applications and environments on high-performance servers. Lres4004tf-poe is developed on the basis of Intel dual port Ethernet MAC + PHY controller. Gigabit Poe working channel and Gigabit fiber working channel are independent of each other, and can be used flexibly with different fiber modules in different requirements. At the same time, it can also expand the bandwidth through link aggregation, which can save PCI express channel resources without occupying bus bandwidth.
