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 kilo...

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 t...

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 distan...

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 signal...

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 switc...

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 ...

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 p...

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) ...

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 ca...

In recent years, there have been many brands of industrial switches, which are widely used in many fields, such as: intelligent transportation, rail transit, electric power, mining and other fields. Due to the need to consider many factors, such as the task si...
