Difference between 1000M network card RJ45 and optical port

Nowadays, gigabit network cards on the market are different, mainly in terms of interfaces, uses, chips, etc. According to the types of interfaces, gigabit network cards can be divided into electrical ports and optical ports. Many users pay more attention to the differences and uses of the two. The electrical ports of gigabit network cards refer to various twisted pair interfaces (sometimes including coaxial cable ports) such as RJ-45 on servers or switches, and mainly use electricity as the information carrier, Suitable for small enterprises with short distance transmission. The optical port of gigabit network card refers to various gigabit optical fiber interfaces (mainly SFP interfaces at present) such as SFPs on servers or switches. It uses light as the carrier medium of information and is suitable for medium and large enterprises with long-distance transmission.

In fact, the biggest difference between the two is the efficiency and packet loss rate in the transmission distance. Although eight types of network cables have been introduced and their performance has been optimized, there are still problems in the transmission distance and stability because the gigabit network card of the electrical port uses crystal head material. For example, when the transmission distance is greater than 100 meters, serious packet loss will occur. Even if the transmission distance is less than 100 meters, there will also be packet loss and loss compared with the gigabit network card of the optical port.

However, both optical port gigabit network card and electrical port gigabit network card will support 100M Ethernet, gigabit Ethernet and other transmission protocols, with a transmission rate of 10/100/1000Mbps (adaptive).

Nowadays, gigabit network cards have been widely used in enterprise networks. It is believed that with the increasing demand for the Internet and the maturity of Ethernet technology, the use of optical network cards will tend to be more high-speed, such as 10G optical network cards, 25G optical network cards, 40G optical network cards, 100G optical network cards, etc. In order to meet the growing bandwidth requirements and help users establish efficient Ethernet connections, FEMRICE can provide flexible and scalable input/output (I/O) solutions, such as 10G optical fiber network cards, 25G optical fiber network cards, etc. For more details, please visit the official website of Fremerrick.
