Look here: Fun Fiber Transceiver

In today's era of rapid technological development, the Internet has become more and more important. Nowadays, social networking is very convenient. Through online shopping, communication, and learning, people can now do everything in bed. The future trend will inevitably achieve greater convenience through the network. When it comes to the development and construction of the network, it is inseparable from the large number of applications of optical fiber. How can we realize the optical signal and electricity more quickly and stably in the network construction? The mutual conversion of signals is an important issue we have to consider. Fiber optic transceivers are the key to solving this problem.

What is a fiber optic transceiver?

There is a saying that is good, knowing yourself and knowing each other, can you fight! Fiber optic transceivers should be familiar to everyone, but to talk about what the fiber optic transceiver is, what is the role is not necessarily clear, simply speaking, the fiber optic transceiver is a photoelectric converter, is a kind of electrical signal The network equipment that converts with the optical signal can be applied in a network environment where the Ethernet cannot be covered or the optical fiber cannot be transmitted, such as a fiber-optic broadband service of a large company, network monitoring, etc., wherein network monitoring is used more.

The most basic structure of the optical transceiver is composed of an optical medium conversion chip, an optical signal interface (optical module) and an electrical signal interface (RJ45). When working in the physical layer, the main function of the optical transceiver is to RJ45 electrical signal and light. The signal (optical module) provides an interface for the conversion of electro-optical, optical-electrical signals and various encodings of the physical layer. When working at the data link layer, the main role of the fiber transceiver is to achieve packet packing and decompression, packet MAC formatting, and preliminary error detection (CRC).

Do you understand the two connection options for fiber optic transceivers?

According to the functionality of the fiber transceiver, it is divided into POE fiber transceiver and Ethernet fiber transceiver (including network management type, non-network management type and mini optical transceiver). The POE fiber optic transceiver can not only convert the photoelectric signals to each other, but also has a power supply function, which can supply power for monitoring cameras and the like, which is very convenient. The Ethernet fiber optic transceiver can only perform the photoelectric signal mutual conversion function. Because the functions of POE fiber optic transceivers and Ethernet fiber optic transceivers are different, there will be differences in the use. How do two fiber transceivers work? details as follows:

Let me introduce the POE fiber transceiver:

When we are deploying the network monitoring system, we can directly use the POE fiber transceiver to supply power to the webcam, WIFI, etc., which is an economical network cabling solution. So how is the POE fiber transceiver used? details as follows:

First, insert two SFP optical modules into the optical interface of the POE fiber transceiver and the SFP port of the Gigabit switch, and then connect them by using fiber jumpers.

Second, use the network jumper to connect the electrical interface of the webcam and POE fiber transceiver (RJ45);

Finally, use a network jumper to connect the switch to a network DVR, network DVR, and host.

After power-on, the light on the POE fiber transceiver indicates that the connection is successful.

Then the Ethernet fiber transceiver

When we are deploying a large network, because the transmission distance of the network cable is limited (the maximum transmission distance of the network cable is 100m), the relay device or the fiber jumper is generally selected to complete the wiring, and when the fiber jumper is used, the fiber transmission and reception is generally used. What about fiber optic transceivers? How to access the network? When the optical transceiver is connected to the network, the optical cable is first introduced into the room from the outside, the cable core of the optical cable is welded to the pigtail, and then the welded optical fiber is placed in the optical fiber splice tray in the ODF optical distribution frame, and then reused. The coupler connects it to the fiber jumper;

Secondly, the SFP optical module is inserted into the optical interface of the optical transceiver, and then the optical transceiver is connected by using a fiber jumper;

Finally, the fiber optic transceiver is connected to the switch using a network jumper.

After power-on, the Ethernet fiber transceiver's light is on, indicating that the connection is successful.
