Before, we introduced the characteristics, advantages and connection methods of fiber optic transceivers. I believe that friends who have seen it have a certain understanding of this. Someone may ask about the specific usage of the optical transceiver. Today, the editor of Hangzhou Feichang Technology will take you to learn more about how the optical transceiver is used. Let’s take a look!
How to use optical fiber transceiver:
Since the maximum transmission distance of the network cable (twisted pair) we often use is very limited, the maximum transmission distance of the general twisted pair is 100 meters. Therefore, when we are laying out the connected network, we have to use relay equipment. Of course, other types of lines are used for transmission. Optical fiber is a good choice. The transmission distance of optical fiber is very long. Generally speaking, the transmission distance of single-mode fiber is more than 10, and the transmission distance of multi-mode fiber can reach up to 2 inches. When using optical fibers, we often use optical fiber transceivers:
If you want to know how to use the fiber optic transceiver, you must first know what the fiber optic transceiver has. Simply put, the role of the fiber optic transceiver is the mutual conversion between optical signals and electrical signals. Input the optical signal from the optical port, and output the electrical signal from the electrical port (common RJ45 crystal head interface), and vice versa. The process is roughly as follows: convert electrical signals into optical signals, transmit them through optical fibers, convert optical signals into electrical signals 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 fiber transceiver (may be other equipment) in the computer room of the operator (Telecom, China Mobile, China Unicom) and your home fiber transceiver. If you want to build your own overlay 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 plugged in without any configuration. Optical fiber connector, RJ45 crystal plug connector. But pay attention to the transmission and reception of optical fiber, one for receiving and one for sending, if not, change each other.
Well, the above is the detailed introduction about the use of optical fiber transceiver. I hope you can help you after reading it.
