The trends for China’s network equipment market
New technologies and new applications continue to catalyze the high growth trend of data traffic, which is expected to drive the network equipment market to exceed expected growth. With the growth of global data traffic, the number of Internet devices is also increasing rapidly. At the same time,...Read more -
What is the difference between an Ethernet switch and a router?
Although both are used for network switching, there are differences in function. Difference 1: The load and subnetting are different. There can only be one path between Ethernet switches, so that information is concentrated on one communication link and cannot be dynamically allocated to balance...Read more -
Optical transceiver type & interface type
Optical transceiver is the terminal equipment for optical signal transmission. 1. Optical transceiver type: Optical transceiver is a device that converts multiple E1 (a data transmission standard for trunk lines, usually at a rate of 2.048Mbps, this standard is used in China and Europe) into opti...Read more -
Transmitter? Receiver? Can the A/B end of the fiber media converter be connected casually?
For optical fiber transceivers, the main function of the transceiver is to extend the network transmission distance, which can alleviate the defect that the network cable cannot transmit long-distance to a certain extent, and bring convenience to the last kilometer transmission, but for those who...Read more -
Which fiber media converter transmits and which receives?
When we transmit over long distances, we usually use optical fibers to transmit. Because the transmission distance of optical fiber is very long, in general, the transmission distance of single-mode fiber is more than 20 kilometers, and the transmission distance of multi-mode fiber can reach up t...Read more -
What is the difference between AOC and DAC? how to choose?
Generally speaking, active optical cable(AOC) and direct attach cable (DAC)have the following differences: ① Different power consumption: the power consumption of AOC is higher than that of DAC; ②Different transmission distances: In theory, the longest transmission distance of AOC can reach 100M,...Read more -
What is the role of fiber media converter?
The fiber media converter is a necessary product equipment for the optical communication system. Its main function is the Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals and long-distance optical signals. fiber media converter products are...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 applia...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 -
What are the precautions for industrial switches in daily use?
What are the precautions for industrial switches in daily use? (1) Do not place the device in a place close to water or damp; (2) Do not put anything on the power cable, keep it out of reach; (3) In order to avoid fire, do not knot or wrap the cable; (4) The power connector and other equipment co...Read more -
Function and Application of Industrial Fiber Switch
Industrial Fiber switch (Industrial Switch), also known as industrial Ethernet switch, is a work in the second layer of OSI (data information link layer, defined with reference to “local area network”), according to MAC (network port material key management) Detailed address) identifi...Read more -
How to solve the instability of POE switches
POE switches provide everyone with great convenience and speed, but because of the complete functions of POE switches, it is also not enough. The reliability of POE switches is also the most obvious factor in this deficiency. In order to better POE Switches can be more reliable, and everyone is a...Read more
