Optical fiber transceiver is a kind of Ethernet transmission medium conversion equipment that exchanges Ethernet electrical and optical signals, and is also called a photoelectric converter. The optical fiber that transmits data on the network is divided into multi-mode optical fiber and single-mode optical fiber. Next, let’s take a look at what is a single-mode optical transceiver and what is a multi-mode optical transceiver. Let’s take a look at the application of optical transceivers in high-definition network video surveillance projects!
Single-mode optical fiber transceiver: transmission distance of 20 kilometers to 120 kilometers,
Multimode optical fiber transceiver: the transmission distance is generally 2 kilometers to 5 kilometers.
From the networking application, because multi-mode optical fiber cannot carry out long-distance transmission, it can generally only be used for networking within and between buildings, such as the establishment of internal campus networks in schools.
With the advancement of technology, single-mode fiber has begun to enter long-distance networking operations (from a few kilometers to more than 100 kilometers), and its development momentum is very rapid. Within a few years, high-end applications have entered the homes of ordinary people. Nowadays, some key customers use optical fiber transceivers (so-called FTTH mode, fiber-to-the-home) directly when they open the network at home. The use of optical fiber transceivers for networking has become a very common form for broadcasting and television to develop value-added services.
The so-called dual-fiber optical transceiver uses two optical fibers (one for receiving and one for transmitting), a set of optical transceivers to realize the conversion of electrical signals to optical signals, optical signals and then electrical signals. The emergence of optical fiber transceivers effectively solves the problem of network cables. The problem of transmission distance.

The problem of transmission distance.At the same time, two wavelengths are used to transmit signals -1310nm and 1550nm, that is, one end uses 1310nm wavelength to send, and 1550nm wavelength to receive signals at the same time, using wavelength division multiplexing technology, effectively solving the problem of signal interference.
Generally speaking, if the fiber optic transceiver is placed in the computer room, the solution is more inclined to the centralized fiber optic transceiver rack. Choose this kind of fiber optic transceiver, first, the structure quality is relatively stable, and second,the modular type Structure, the centralized placement of fiber optic transceivers can be realized by placing racks in the computer room. For example, a 14-slot rack can place 14 fiber optic transceivers at a time, and it adopts plug-in installation, which is flexible in maintenance and replacement without interference. The normal operation of other transceivers.
