If you want to know how to pair and use fiber optic transceivers, you must first know what the fiber optic transceivers do. In simple terms, the function of fiber optic transceivers 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 connector), and vice versa. The process is roughly as follows: convert the electrical signal into an optical signal, transmit it through an optical fiber, convert the optical signal into an electrical signal at the other end, and then connect to routers, switches and other equipment. Therefore, fiber optic transceivers are generally used in pairs. For example, the optical transceivers (may be other equipment) in the equipment room of the operator (Telecom, China Mobile, China Unicom) and the optical transceivers in your home. If you want to build your own local area network with fiber optic transceivers, you must use them in pairs. The general optical fiber transceiver is the same as the general switch. It can be used when it is powered on and plugged in, and no configuration is required. Optical fiber socket, RJ45 crystal plug socket. However, pay attention to the transmission and reception of optical fibers.
Precautions for pairing optical transceivers with optical modules
In the design of optical fiber network structure, many projects adopt the method of optical fiber transceiver + optical module connection. So, what do we need to pay attention to when connecting and purchasing products for optical fiber networks in this way?
1. The speed of the optical fiber transceiver and the optical module must be the same, for example, the gigabit transceiver corresponds to the 1.25G optical module
2. The wavelength and transmission distance must be consistent, for example, the wavelength of 1310nm is used, and the transmission distance is 10KM
3. The optical module types need to be of the same type, such as multi-mode dual-fiber, or single-mode single-fiber
4. Attention should be paid to the selection of fiber jumper pigtail interface. Generally, the SC port is used for fiber optic transceivers, and the LC port is used for optical modules.
