How to Use Fiber Media Converter in Your Network?
1. The introduction of fiber media converter
A fiber media converter is an Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals and long-distance optical signals and is also called a fiber converter in many places. The products are generally used in the actual network environment where the Ethernet cable cannot cover and must use optical fiber to extend the transmission distance. They are usually located at the access layer application of the broadband metropolitan area network; For example, monitoring the high-definition video transmission of the security project; helping to connect the last mile of optical fiber to the outer network of metropolitan area network has also played a huge role.
2. The role of fiber media converter
Fiber media converter are generally used in the actual network environment where Ethernet cables cannot cover and must use optical fiber to extend the transmission distance. At the same time, they also play a huge role in helping connect the last kilometer of the optical fiber to the metropolitan area network and the outer network. With fiber media converter, it also provides a cheap solution for users who lack the capital, labor or time to upgrade the system from copper to fiber. The function of the fiber media converter is to convert the electrical signal we want to send into an optical signal and send it out. At the same time, we can convert the received optical signal into an electrical signal and input it to our receiver.
3. Fiber media converter classification
① According to the nature of points
Divided by the nature of the fibers, it can be divided into multimode fiber media converter and single mode fiber media converter. The difference between them is that the transmitted distance is different. Multi-mode media converters generally have a transmission distance of 2 to 5 kilometers, while single-mode media converters cover a range of 20 to 120 kilometers.
② According to send and receive data points
Single fiber media converters and dual fiber media converters
are classified according to the fiber in need. Single fiber media converters transmit and receive data on one fiber, and dual fiber media converters receive and transmit data on a pair of fibers.
③ According to network management points
According to network management, it can be divided into network management fiber media converters and non-network management fiber media converters.
④ Divided by management type
According to the management type, it can be divided into managed Ethernet fiber media converters and unmanaged Ethernet fiber media converters. Managed Ethernet fiber media converters support carrier-grade network management, while non-managed Ethernet fiber media converters use hardware dial switch to set the working mode of the electrical interface, plug and play.
⑤ According to the way of work
According to the mode of work, full-duplex mode means that when the data is transmitted and received by two separate streams in two different transmission lines, the two parties can both perform sending and receiving operations at the same time. Such a transmission mode is full-duplex. On the other side，if the data cannot be transmitted at the same time，it’s Half Duplex mode.
4. Fiber media converter application range
① Implement of interconnection between switches.
② To achieve the interconnection between switches and computers.
③ To achieve the interconnection between computers.
④ Transmission relay: when the actual transmission distance exceeds the nominal transmission distance of the converters, especially when the actual transmission distance exceeds 120 Km, two converters are used to relay in back-to-back or the light-light way if the local conditions permit. It is a very cost-effective solution.
⑤ Single/multi-mode conversion: When there is a need for a single/multi-mode fiber connection between the network, you can use a single multi-mode converter to connect, to solve the problem of single/multi-mode fiber conversion.
⑥ Wavelength division multiplexing transmission: When long-distance optical cable resources are insufficient, in order to increase the use of optical fiber cable and reduce the cost, the converters can be used in conjunction with the wavelength division multiplexer, so that two-way information could transmit on the same pair of optical fiber.
5. The use of fiber media converter
Because the maximum transmission distance of the network cable (twisted pair) that we often use has one big limitation, the maximum transmission distance of generally twisted pair is 100 meters. Therefore, when we are laying larger networks, we have to use relay equipment. Of course, three are other types of lines are used for transmission. The optical fiber is a good choice. The transmission distance of optical fiber is very long. In general, the transmission distance of single-mode optical fiber is more than 10 kilometers, and the transmission distance of multi-mode optical fiber is up to 2 kilometers. When using fiber optics, we often use fiber media converter:
To understand how a fiber media converter is used, it is important to know what a fiber optic converter does. In simple terms, the role of fiber media converter is the conversion between optical signals and electrical signals. The optical signal is input from the optical port and the electrical signal is output from the electrical port (common RJ45 plug connector) and vice versa. The process is roughly as follows: The electrical signal is converted into an optical signal, transmitted through the optical fiber, and then converted to an electrical signal at the other end, and then access routers, switches and other equipment.
Therefore, fiber media converter are generally used in pairs. For example, fiber media converters (possibly other equipment) in the computer room of ISPs (China Telecom, China Mobile, and China Unicom) and fiber converters in your home. If you want to set up your own LAN with a fiber converter, it must be used in pairs.
Generally, the fiber media converter is the same as the general switch, just turned on and plugged in. The configuration does not need to be done. Optical fiber plugs optical port and RJ45 plugs electrical interface. However, attention should be paid to the sending and receiving of optical fibers. One receives and one sends conversely you should change each other.
Now everyone's understanding of optical converters should be very clear, Sopto has more knowledge about other optical communications equipment, welcome to continue to check!
