How to turn an ordinary switch into a PoE switch？
If you want to turn an ordinary switch into a PoE switch, directly assembling an ordinary switch into a PoE switch cannot fully realize power supply and data transmission at the same time. Unless you know the relevant knowledge of the switch well, you can only meet your needs in other ways , Here...Read more -
Can a PoE switch be used as a normal switch?
PoE switch is a new type of multifunctional switch. With the wide application of PoE switch, people have a certain understanding of PoE switch. However, many people think that PoE switches can generate electricity by themselves. This statement is not correct. Generally speaking, PoE switch power ...Read more -
Analysis of the characteristics of the Layer 2 industrial switch
The development of the two-layer switching technology is relatively mature. The two-layer industrial switch is a data link layer device. It can identify the MAC address information in the data packet, forward it according to the MAC address, and record these MAC addresses and corresponding ports ...Read more -
What are the advantages of Layer 3 switches?
The technology of the Layer 3 switch is becoming more and more mature and its applications are becoming more and more extensive. In a certain range, it has more advantages than routers, but there is still a big difference between the three-layer switch and the router. In the local area network, t...Read more -
Introduction to the working principle of Layer 3 switches
Each network host, workstation or server has its own IP address and subnet mask. When the host communicates with the server, according to its own IP address and subnet mask, as well as the server’s IP address, determine whether the server is in the same network segment as itself: 1. If it i...Read more -
POE switch application scheme and functional characteristics introduction
PoE switch refers to a switch that can provide network power supply to remote power receiving terminals through a network cable. It includes two functions: network switch and PoE power supply. It is a relatively common power supply device in PoE power supply systems. So, what are the application ...Read more -
Why should optical transceivers be used in pairs?
Will new customers always ask for a pair of optical transceivers? Yes, in fact, optical transceivers are used in pairs. Optical transceivers are used in optical and electrical converters that use optical fibers as the carrier. The sender and receiver must be the same device. Why should optical tr...Read more -
Introduction to SDH Optical Transceiver
