What Is A Fiber Optic Transceiver

- Oct 13, 2020-

The fiber optic transceiver is an Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals and long-distance optical signals. It is also called a photoelectric converter in many places. 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 in the access layer application of broadband metropolitan area networks; such as: high-definition video image transmission for monitoring security projects; It also played a huge role in helping to connect the last mile of optical fiber to the metropolitan area network and the outer network.


   Fiber optic transceivers are commonly used network equipment in our intelligent weak current projects. We can classify fiber optic transceivers according to fiber type and transmission type. According to the type of fiber, it can be divided into multi-mode fiber transceiver and single-mode fiber transceiver. However, because the cost of multi-mode fiber is higher and the light attenuation is larger than that of single-mode fiber, the transmission distance of multi-mode fiber is shorter. Mainly single-mode fiber.


From the transmission type, it can be divided into single-core transceiver and dual-core transceiver. We can distinguish it from the name. Single-core transceiver data is received and sent through one-core optical fiber, while dual-core transceiver is through Two-core optical fiber, the receiving end and the transmitting end are distinguished between RX and TX. The RX and TX of the receiving end and the transmitting end must be cross-connected to send and receive data normally, that is, the RX of the receiving end must be connected to the TX of the transmitting end.
