What is a fiber optic network card? How does it work?
A fiber optic NIC is a network adapter or network interface card (NIC) that primarily connects devices such as computers and servers to a data network. Usually the backplane of the optical fiber network card has one or more ports, which can be connected to the network jumper of the RJ45 interface or the DAC high-speed line of the SFP/SFP+ port, and the AOC active optical cable.
Optical network cards can transmit signals at the physical layer and forward packets at the network layer. No matter which layer of the OSI seven-layer model the fiber optic network card is located in, it can act as a “middleman” between the server/computer and the data network. When a user sends an Internet access request, the fiber optic network card will obtain data from the user’s device, send it to the server on the Internet, and then receive the data required by the user to access the Internet from the Internet.

3. Application fields of Huizhou YOFC Ethernet fiber optic network card
Computer Optical Network Cards – Most of today’s computer motherboards have built-in optical network cards that support 10/100/1000Mbps transfer rates for one computer to communicate with another computer or network.
Server Optical Network Card – The primary function of a server optical network card is to manage and process network traffic. Compared with the fiber optic network card on the computer, the server fiber optic network card usually requires a higher transmission rate, such as 10G, 25G, 40G or even 100G. In addition, since the server fiber optic network card has a controller, the CPU usage is low, and more tasks can be performed in the CPU.
