The fiber media converter is the necessary 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. So, what is the role of fiber media converters? Next, let’s learn more about it!

fiber optical media converters

Fiber media converters are generally used in actual network environments that cannot be covered by Ethernet cables and must use optical fibers to extend the transmission distance, and are usually located in the access layer application of broadband metropolitan area networks. Such as high-definition video and image transmission for monitoring security projects; at the same time, it also plays a huge role in helping to connect the last mile of fiber optic lines to the metropolitan area network and the outer network.


Since the maximum transmission distance of the commonly used network cable (twisted pair) is very limited, the maximum transmission distance of the twisted pair is generally 100 meters. Therefore, when we are deploying a larger network, we have to use relay devices. Optical fiber is a good choice. The transmission distance of optical fiber is very long. Generally speaking, the transmission distance of single-mode fiber is more than 10 kilometers, and the transmission distance of multi-mode fiber can reach up to 2 kilometers. When using optical fibers, we often use fiber media converters:


If you want to know how to use a fiber media converter, you must first know what the fiber media converter does. Simply put, the role of the fiber media converter is the mutual 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 crystal connector) and vice versa. The process is rough as follows: convert the electrical signal into an optical signal, transmit it through an optical fiber, convert the optical signal into an electrical signal at the other end, and then connect to routers, switches, and other equipment.


Therefore, fiber optic media converters are generally used in pairs. For example, the fiber optic media converters (maybe other equipment) in the computer room of the operator (Telecom, China Mobile, China Unicom) and the fiber optic media converters in your home. If you want to build your own local area network with fiber optic media converters, you must use them in pairs. The general fiber media converter is the same as the general switch. It can be used when it is powered on and plugged in, and no configuration is required. Optical fiber socket, RJ45 crystal plug socket. However, pay attention to the transmission and reception of optical fibers.
