Four precautions for the use of fiber optic transceivers
In network construction and application, since the maximum transmission distance of the network cable is generally 100 meters, it is necessary to use relay equipment such as optical fiber transceivers when deploying a long-distance transmission network. Optical fiber transceivers are generally us...Read more -
What are the common faults and solutions of HDMI video optical transceivers?
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...Read more -
What is the maximum transmission distance of the POE power supply switch?
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...Read more -
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 ...Read more -
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
