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 ...

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 canno...

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 i...

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...
