In the vast realm of networking technology, understanding network card models can be a daunting task.   1、The model number contains "T": the interface type is Ethernet interface. For example: I350-T2, X540-T2, X710-T4   2. The model includes "F" and "D": optical fiber interface, used to connect to optical fiber networks, with the characteristics of high-speed transmission and stability. Common abbreviations for optical interfaces: SFP+, SFP28, QSFP, etc. For example: I350-F2, X520-DA2, E810-CQDA2   3. The model number contains "SR": the network card comes with its own module, and the modules are usually divided into single-mode and multi-mode. Single-mode is often used for long-distance transmission, and the wavelengths are: 1310, 1550, and 1490. No light can be seen when the power is on. Multi-mode is often used for short-distance transmission. The wavelength is 850nm. Red light can be seen when the power is on.   4. Finally, the numerical digit at the end of the model holds the key to understanding the quantity of external interface connections. The last number 1 or 2 or 4: the number of external interface connections. For example: X520-DA1, I210-T1, I350-T4, X710-DA4, X520-DA2.   The above information only applies to IN network cards.
