With the rapid development of information construction, people's demand for multimedia communications such as data, voice, and images is getting stronger and stronger. Therefore, the Ethernet broadband access method has been mentioned as an increasingly important position. However, the traditional Category 5 cable can only transmit Ethernet electrical signals for 100 meters, and it cannot meet the needs of the actual network environment in terms of transmission distance and coverage. At the same time, fiber optic communication has been widely used for its advantages such as large information capacity, good confidentiality, light weight, small size, no repeater, and long transmission distance.
The optical fiber media converter adopts the optical fiber as a high-speed propagation medium to solve the problem of Ethernet transmission. In some large-scale enterprises, the optical fiber is used as the transmission medium to build the backbone network during network construction, and the internal LAN transmission medium is generally copper wire. How can the LAN be connected to the optical fiber backbone network? This requires conversion between different ports, different line shapes, and different fibers and guarantees link quality. The emergence of optical fiber media converter converts twisted-pair electrical signals and optical signals to each other, ensuring smooth transmission of data packets between the two networks, and at the same time it extends the transmission distance limit of the network from 100 meters to 100 kilometers of copper wires (single Mode fiber).
What is a fiber media converter
Optical fiber media converter is an Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals with long-distance optical signals. It is also called a photoelectric converter in many places. The product is generally applied in the actual network environment where the Ethernet cable cannot cover, and optical fiber must be used to extend the transmission distance, and is usually positioned in the access layer application of the broadband metropolitan area network; meanwhile, it helps to connect the last mile of optical fiber line to the metropolitan area The Internet and the outer network also played a huge role.
When enterprises are building their information infrastructure, they usually pay more attention to network equipment such as routers, switches, and even network cards for node data exchange, but they often ignore media conversion, which is not essential to the core of the network. Especially in some government agencies and enterprises that require a high degree of informationization and large data traffic, the network construction needs to be directly connected to the backbone network using optical fiber as the transmission medium, and the transmission medium of the internal LAN of the enterprise is generally copper wire Media conversion equipment for smooth transmission of data packets between different networks becomes a necessity.
At present, there are many foreign and domestic manufacturers of optical fiber media converter, and the product line is also very rich. In order to ensure complete compatibility with network equipment such as network cards, repeaters, hubs, and switches from other manufacturers, fiber optic media converters must strictly comply with Ethernet such as 10Base-T, 100Base-TX, 100Base-FX, IEEE802.3, and IEEE802.3u Network standards, in addition to EMC protection against electromagnetic radiation should comply with FCC Part15. Nowadays, major domestic operators are vigorously building residential networks, campus networks, and enterprise networks, so the use of optical fiber media converter is constantly increasing to better meet the needs of access network construction.
