HDMI optical transceiver is a terminal device for optical signal transmission. In a wide range of applications, it is often necessary to transmit the HDMI signal source to a distance for processing. The most prominent problems are: color cast and blur of the signal received at a distance, ghostin...
What is the maximum transmission distance of the POE power supply switch?

What is the maximum transmission distance of th...

To know the maximum transmission distance of PoE, we must first figure out what are the key factors that determine the maximum distance. In fact, using standard Ethernet cables (twisted pair) to transmit DC power can be carried over a long distance, which is far greater than the transmission dist...
What is an optical module?

What is an optical module?

The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic device includes two parts: transmitting and receiving. Simply put, the function of the optical module is to convert the electrical signal into an optical signal at the sending ...

What is the difference between an Ethernet switch and a router?

What is the difference between an Ethernet swit...

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...
Optical transceiver type & interface type

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...
Transmitter? Receiver? Can the A/B end of the fiber media converter be connected casually?

Transmitter? Receiver? Can the A/B end of the f...

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...
Which fiber media converter transmits and which receives?

Which fiber media converter transmits and which...

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...
What is the difference between AOC and DAC? how to choose?

What is the difference between AOC and DAC? how...

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,...
What is the role of fiber media converter?

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...
When purchasing a switch, what is the appropriate IP level of an industrial switch?

When purchasing a switch, what is the appropria...

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...
What is the difference between a POE switch and a normal switch?

What is the difference between a POE switch and...

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...
