What should be paid attention to when choosing a compatible optical module?
The optical module is the core accessory of the optical communication system and plays a vital role in optical fiber communication. It mainly completes the photoelectric conversion function. The quality of the optical module determines the transmission quality of the optical network. Inferior opt...Read more -
What is the difference between a POE switch and a normal switch?
1. Different reliability: POE switches are switches that support power supply to network cables. Compared with ordinary switches, power-receiving terminals (such as APs, digital cameras, etc.) do not need to perform power wiring, and are more reliable for the entire network. 2. Different function...Read more -
When purchasing a switch, what is the appropriate IP level of an industrial switch?
The protection level of industrial switches is drafted by IEC (International Electrotechnical Association). It is represented by IP, and IP refers to “ingress protection. So, when we buy industrial switches, what is the appropriate IP level of industrial switches? Classify electrical appli...Read more -

What are the management methods of switches?
There are two types of switch management methods: 1. Management of the switch through the console port of the switch belongs to out-of-band management, which is characterized by no need to occupy the network interface of the switch, but the cable is special and the configuration distance is short...Read more -
How to choose the right switch correctly?
At present, there are many types of switches on the market, and the quality is uneven, so what indicators should we pay attention to when purchasing? 1. Backplane bandwidth; Layer 2/3 switching throughput; 2. VLAN type and quantity; 3. Number and type of switch ports; 4. Support protocols and me...Read more -
What is the difference between a Layer 2 switch and a Layer 3 switch?
The essential difference between a layer-2 switch and a layer-3 switch is that the working protocol layer is different. A layer-2 switch works at the data link layer, and a layer-3 switch works at the network layer. It can be simply understood as a layer 2 switch. You can think that it only has t...Read more -
What are the differences between electrical port modules and optical modules?
The copper port module is a module that converts an optical port into an electrical port. Its function is to convert optical signals into electrical signals, and its interface type is RJ45. The optical-to-electrical module is a module that supports hot swapping, and the package types include SFP,...Read more -
Can Industrial Ethernet Switches from Different Manufacturers Build a Redundant Ring Network?
As an important data communication product, industrial Ethernet switches must be open and compatible with products from multiple manufacturers to ensure long-term stable and safe operation of the system. If you only rely on a certain manufacturer, the risk is extremely high. Therefore, based on s...Read more -
How to Choose a Security Switch?
Security switches, also known as PoE switches, are designed for simple network environments such as homes, school dormitories, offices, and small monitoring. First, it is wrong to use the capacity of the switch to calculate the number of cameras with cameras. It is still necessary to refer to the...Read more -
What is a Layer 3 switch?
With the general development and application of network technology, the development of switches has also undergone great changes. The earliest switches developed from very simple switches to layer 2 switches, and then from layer 2 switches to layer 3 switches. So, what is a Layer 3 switch? ...Read more -
How to Install the Din-rail Industrial Switch?
There are various classifications of industrial switches, which can be divided into manageable industrial switches and unmanaged switches. According to the installation method, they can be divided into rail-mounted industrial switches and rack-mounted industrial switches. So how are rail-mounted ...Read more
