As a signal conversion and transmission device, the optical fiber transceiver converts the Ethernet signal at the front end into an optical signal for remote transmission through the transmitting end of the optical fiber transceiver. The receiving end of the optical fiber transceiver converts the optical signal and the into an electrical signal.
There are many ways to classify fiber optic transceivers. One of the most common methods is to classify them according to the fibers used. They are mainly divided into single-mode fiber optic transceivers and multi-mode fiber optic transceivers. The transmission distance is relatively long and can cover a plan of 20 kilometers to 120 kilometers, which is also selected according to the transmission distance that single-mode fiber can reach. Due to the relatively short transmission distance of multimode fiber, it can only cover the distance of 2 kilometers to 5 kilometers. Therefore, the data transmission distance supported by multimode fiber transceivers is also relatively short, and the data can only be completed within the plan of 2 kilometers to 5 kilometers. transmission.
In the comparison of the quotations of the two fiber optic transceivers, we found that the single-mode fiber optic transceiver is more expensive than the multi-mode fiber optic transceiver. Small and medium-sized companies are bound by their own plans, and their capital investment is not large. Therefore, multimode optical fiber transceivers are more suitable for small and medium-sized companies. Of course, this is not the only reason. Another reason is that the network of small and medium-sized companies is generally relatively full and not as scattered as large companies. Therefore, the required coverage of fiber optic transceivers does not require too much, and this is exactly the point of multimode fiber. Characteristics. Most of the small and medium-sized companies still use 100M networks. Therefore, we only need to choose 100M multimode fiber transceivers to meet the needs of users.
Twisted pair is widely used in our general network. For example, in a family or in a building, twisted pair is used to complete the networking. However, the twisted pair can only insist on data transmission at a distance of 100 meters. If it exceeds 100 meters, the data transmission speed will be seriously affected. Nowadays, the network structure of some small and medium-sized companies is relatively large, and the connection between some computers and computers or the connection between the communication machine and the communication machine exceeds the distance of 10 meters. Obviously, the twisted pair cannot be completed more than 100 meters. The connection between points and points at a distance of meters, so we need to use optical fibers here, because optical fibers can complete network connections with the longest distance of more than 10 kilometers, and the use of optical fiber connections also has the advantages of a large amount of information transmission and safety. Upscale features. In the network of small and medium-sized companies, there are still many points of connection that do not exceed ten meters, such as the network within a unit, so we still use twisted-pair cables in some networks; and in more than ten meters Between the two points in the distance, we are again connected by the selected optical fiber medium. Therefore, we must think about the connection between twisted pairs and optical fiber. The ten/ten 0M optical fiber transceiver is the device that completes the connection between the twisted pair and the optical fiber. It mainly converts the signal transmitted by the twisted pair into a transmission signal that can pass through the optical fiber. Of course, this is also bidirectional. Convert the signal transmitted in the optical fiber to the signal that can be transmitted in the twisted pair to complete the data transmission between the networks.
Of course, the method of using optical fiber transceivers is not only this one, it can also be used in large metropolitan area networks. Assuming that the distance between two points exceeds the signal distance that the optical fiber can transmit, two optical fiber transceivers can be used back-to-back. The method of connection, which is also called relay, will extend the data transmission interval between two points. The fiber optic transceiver can also complete the interconnection between the communication machine and the communication machine, the interconnection between the computer and the computer, and the interconnection between the communication machine and the computer, etc. Users can use it according to their own practice conditions.
