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 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 20 kilometers, and the transmission distance of multi-mode fiber can reach up to 2 kilometers. When using optical fibers, we often use fiber media converter.

The function of fiber media converter is to convert 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 roughly 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 media converter are generally used in pairs.
