Media converters are generally divided into two types, one is an Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals and long-distance optical signals, usually called photoelectric converters; After the optical signal is converted into an electrical signal, it is then converted into another optical signal, also known as a fiber conversion repeater. Products are generally used in actual network environments where Ethernet cables cannot be covered and optical fibers must be used to extend the transmission distance, and are usually positioned at the access layer of broadband metropolitan area networks; at the same time, they help connect the last mile of optical fiber lines to metro It also plays a huge role on the Web and beyond.

We all know that a network is composed of various optical devices, and fiber optic transceivers are an important part of it. When connecting the fiber optic transceiver to the network, the fiber optic cable must first be brought in from the outside. The optical cable is spliced in the optical cable box, that is, the terminal box. The welding of optical cables is also a science. The optical cables need to be stripped, the thin fibers in the optical cables and the pigtails are welded, and then put in the box after welding. The pigtail should be pulled out, connected to the ODF (a frame, connected with a coupler), and then connected to the jumper with the coupler, and finally the jumper is connected to the fiber optic transceiver. The next sequence of connections is router----switch---LAN---host. In this way, the fiber optic transceiver is connected to the network.
