According to different transmission protocols, network cards can be divided into Ethernet cards, FC network cards, and ISCSI network cards. The Ethernet card is also called the optical fiber network card. It is mainly plugged into the server and is commonly us...

Switching is a general term for technologies that send the information to be transmitted to the corresponding routing that meets the requirements by manual or automatic equipment according to the requirements of transmitting information at both ends of the com...

A PoE switch is a switch that supports power supply to the network cable. Compared with ordinary switches, the power receiving terminal (such as AP, digital camera, etc.) does not need to be wired for power supply, which is more reliable for the entire network...

Understanding the performance of optical fiber and copper wire can make a better choice. So what characteristics do optical fiber and copper wire have? 1. Copper wire characteristics In addition to the above-mentioned good anti-interference, confidentiality, a...

The choice of data center transmission media is always a controversial topic, especially in dedicated facilities (such as data centers). Technical and business issues need to be considered. Some people think that copper wires should be chosen, while others thi...

When purchasing an industrial switch, customers will be asked whether they want single-mode single fiber, single-mode dual-fiber, multi-mode dual-fiber, etc., and where they are used. These will only be understood when they have a clear understanding of the pu...

How does the PoE injector work? When switches or other devices without power supply function are connected to powered devices (such as IP cameras, wireless APs, etc.), the PoE power supply can provide power and data transmission support for these powered devic...

PoE (Power over Ethernet) refers to a power over Ethernet technology that simultaneously transmits power and data through a twisted pair cable. The application of this technology can effectively improve the stability and flexibility of the network, so it is wi...

Transmission rate is a crucial factor in determining the type of Ethernet switch port. At present, the transmission rate of Ethernet switches is 1G/10G/25G/40G/100G or even higher. The following are the mainstream port types of these Ethernet switches with dif...

How to measure the network delay in an Ethernet switch? As can be seen from the previous chapter, switch delay is one of the key factors leading to network delay. So how do we measure switch latency? Switch delay is measured from port to port on the Ethernet s...
