    What is a fiber optic transceiver? What are the uses? Let's have a look with Fctel!
    Optical fiber transceiver is a kind of Ethernet transmission media conversion unit which can exchange short-distance twisted pair electrical signal and long-distance optical signal. It is also called fiber converter in many places. The products are generally used in the actual network environment where the Ethernet cable cannot cover and the optical fiber must be used to extend the transmission distance, and are usually located in the access layer application of broadband man; Such as: monitoring the high-definition video image transmission of safety engineering; At the same time, it has played a huge role in helping to connect the last kilometer of optical fiber to the metropolitan area network and the outer network.
    2、 Function of optical fiber transceiver
    Optical fiber transceivers are generally used in the actual network environment where Ethernet cable cannot cover and optical fiber must be used to extend the transmission distance. At the same time, they also play a huge role in helping to connect the last kilometer of optical fiber line to the metropolitan area network and the outer network. With optical fiber transceiver, it also provides a cheap solution for users who need to upgrade the system from copper wire to optical fiber and lack of funds, manpower or time. The function of optical fiber transceiver is to convert the electrical signal we want to send into optical signal and send it out. At the same time, it can convert the received optical signal into electrical signal and input it to our receiving end.
    3、 Classification of optical fiber transceivers
1. By nature
According to the properties of optical fiber, it can be divided into multimode optical fiber transceiver and single-mode optical fiber transceiver. The difference between them is that the transmission distance is different. The general transmission distance of multi-mode transceiver is between 2km and 5km, while the coverage range of single-mode transceiver is from 20km to 120km.
2. By sending and receiving data
The single fiber optical transceiver and the double fiber optical transceiver are classified according to the required optical fiber, and the single fiber optical transceiver receives and transmits the data on one optical fiber; The data received and transmitted by the dual fiber optical transceiver is transmitted on a pair of optical fibers.
3. By network management
According to network management, it can be divided into network management optical fiber transceiver and non network management optical fiber transceiver.
4. By management type
According to the management type, it can be divided into network management type Ethernet optical fiber transceiver and non network management type Ethernet optical fiber transceiver. Network management type Ethernet optical fiber transceiver supports carrier level network management, while non network management type Ethernet optical fiber transceiver sets the interface working mode through hardware dial switch, plug and play.
5. By work style
According to the working mode, the full duplex mode means that when the data transmission and reception are shunted and transmitted by two different transmission lines respectively, both sides of the communication can transmit and receive at the same time. This transmission mode is the full duplex mode.
