Application and Networking of Optical Fiber Transceivers

1.One-to-one transmission 

This is the most common application method of fiber optic transceivers. The traditional one-to-one method, that is, the front end is 1 optical and 1 electrical, and the back end is 1 optical and 1 electrical, or the front end is 1 optical and 2/4/8 electrical ports, and the back end is 1 optical and 1 electrical. electrical connection. There are many applications in small and medium-sized long-distance networks, and it is more obvious that there is only one pair of optical fiber transceivers.

For example the following transceiver example:


2.The application of optical fiber transceiver centralized power supply rack

 With a large number of applications of optical fiber transceivers in the network monitoring optical fiber transmission layer, the application of centralized power supply racks at the computer room end is becoming more and more common, which eliminates the trouble of power wiring, saves manpower, and maintains the overall layout of the computer room.

The rack-mounted fiber optic transceiver is a fiber optic transceiver with a rack structure. Its power supply realizes double automatic backup and uninterrupted work. The rack can be inserted into multiple fiber optic transceiver modules at the same time. Each optical transceiver module can be of different types. Each module can be plugged and unplugged on the rack independently of each other, and can also work in cooperation with each other to provide network diagnostics for itself. Each slot in the rack supports hot-plugging.

Look at his shape to know its application.


3. Application of Cascaded Fiber Optic Transceivers (Optical Fiber Switches)

At present, several products are mainly used in 2-optical and 2-electrical, 2-optical and 3-electrical, 2-optical and 4-electrical, and 2-optical and 8-electrical.

 In the actual engineering cabling process, if the optical fiber equipment in some areas is difficult, you can consider 2-optical multi-electrical fiber optic transceivers. Multiple fiber switches are connected in series on one core fiber, and each fiber switch can be connected to multiple network switches. .

Of course, the shortcomings of this link method are also obvious. Once the middle chain layer fails, it will directly affect the use of the following chain layer transceivers. In the actual fiber optic wiring scheme design, some fiber resources are scarce or the fiber optic equipment is more difficult. area, using this cascade link scheme. For example, highways, project renovation projects, etc.

Its application is as follows:


4. Application of convergent fiber optic transceivers (fiber switches)

 Common products are 4 light 1/2 electricity, 8 light 1/2 electricity and so on.

Converged fiber optic transceivers are commonly used in some small network monitoring projects. They are many-to-one link methods, and are actually also called fiber optic aggregation switches.

The 4-optical 1/2-electrical or 8-optical 1/2-electrical fiber optic switch at the computer room side directly replaces multiple 1-optical 1-electrical fiber optic transceivers, and is directly connected to the NVR through the Gigabit Ethernet port of the fiber-optic switch, reducing one computer room side. Application of network switch.

Its application is as follows:


5. Application of ring network fiber optic transceiver

At present, the application of ring network products on the market is relatively small, and the production cost of the products is relatively high. At present, they are mainly used in some government projects and some special industries.

In different environments and networks, the applications of fiber optic transceivers are also different. The above five networking methods have applications in practical projects.
