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.The product is 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 is usually positioned in the access layer application of the optical fiber broadband metropolitan area network; at the same time, it helps to connect the last mile of the optical fiber to the city. The local area network and the outer network also played a huge role.

Simply put, the role of the fiber optic transceiver 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 head interface), and vice versa.The process is roughly: converting electrical signals into optical signals, transmitting them through optical fibers, and then converting optical signals into electrical signals at the other end, and then connecting them to routers, switches and other equipment.

What are the classifications of fiber optic transceivers

The different viewing angles make people have different understandings of fiber optic transceivers:

For example, according to the transmission rate, it is divided into single 10M, 100M fiber optic transceivers, 10/100M adaptive fiber optic transceivers and 1000M fiber optic transceivers;

According to the working mode, it is divided into fiber optic transceivers working at the physical layer and fiber optic transceivers working at the data link layer;

From a structural point of view, it is divided into desktop (stand-alone) fiber optic transceivers and rack-mounted fiber optic transceivers;

According to the different access fibers, there are two names: multi-mode fiber transceiver and single-mode fiber transceiver.

In addition, there are single-fiber fiber optic transceivers and dual-fiber fiber optic transceivers, built-in power fiber optic transceivers and external power fiber optic transceivers, as well as managed fiber optic transceivers and unmanaged fiber optic transceivers.

Fiber optic transceivers break the 100-meter limitation of Ethernet cables in data transmission, relying on high-performance switching chips and large-capacity buffers, while truly achieving non-blocking transmission and switching performance, it also provides balanced traffic, isolation of conflicts and Error detection and other functions ensure high security and stability during data transmission.

Where is the application range of fiber optic transceivers

In essence, the optical fiber transceiver only completes the data conversion between different media, which can realize the connection between two switches or computers within 0-120Km, but the actual application has more expansion.

1. Realize the interconnection between switches.
2. Realize the interconnection between the switch and the computer.
3. Realize the interconnection between computers.
4. Transmission relay: When the actual transmission distance exceeds the nominal transmission distance of the transceiver, especially when the actual transmission distance exceeds 120Km, if the site conditions permit, use 2 transceivers for back-to-back relay or light-to-optical conversion The relay is a very cost-effective solution.
5. Single-multi-mode conversion: When a single-multi-mode fiber connection is needed between networks, a single-multi-mode converter can be used to connect, which solves the problem of single-multi-mode fiber conversion.
6. Wavelength division multiplexing transmission: When the long-distance optical fiber cable resources are insufficient, in order to increase the utilization rate of the optical cable and reduce the cost, the transceiver and the wavelength division multiplexer can be used together to transmit the two channels of information on the same pair of optical fibers.
