In optical fiber network cabling, the application of optical fiber transceivers has become more and more common. The following briefly introduces several common optical fiber transceiver networking methods.

1、Common application methods of fiber optic transceivers

The traditional one-to-one method, that is, the front end 1 optical 1 electrical optical fiber transceiver, the back end 1 optical 1 electrical optical fiber transceiver, or the front end 1 optical 2/4/8 electrical port optical fiber switch, the back end 1 optical 1 electrical optical fiber transceiver The connection method of the device.

2、Application of Centralized Power Supply Rack for Optical Fiber Transceiver

With the large number of applications of optical fiber transceivers in the network monitoring optical fiber transmission layer, centralized power supply at the computer room end, and the application of racks are becoming more and more common, eliminating the trouble of power wiring, saving manpower, and maintaining the beauty of the overall layout of the computer room end.

3、Application of cascaded fiber optic transceiver (fiber switch)

At present, several products mainly used are 2 optical 2 electrical optical fiber switch, 2 optical 3 electrical optical fiber switch, 2 optical 4 electrical optical fiber switch, 2 optical 8 electrical optical fiber switch and so on.

In the actual engineering wiring process, it is more difficult to lay optical fibers in some areas, so you can consider 2 optical multi-electric optical fiber transceivers. Multiple optical switches are connected in series on one core optical fiber, and each optical fiber switch can be connected to multiple network switches. Of course, the shortcomings of this link method are also obvious. Once the intermediate link layer fails, it will directly affect the use of the following link layer transceivers. In the actual optical fiber wiring scheme design, some optical fiber resources are scarce or optical fiber laying is more difficult. Area, using this cascading link scheme. For example, highways, project renovation and other projects.

4、Convergence type optical fiber transceiver (optical switch) application

Common products include 4 optical 2 electrical optical fiber switches, 8 optical 1/2 electrical optical fiber switches, and 16 optical 8 electrical optical fiber switches.

Convergent fiber optic transceivers are commonly used in some small network monitoring projects, and are a many-to-one link mode.

The converged fiber optic switch at the computer room 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 switch, reducing the application of a network switch at the computer room.

5、Parallel application of cascaded fiber optic transceivers and convergent fiber optic transceivers

With the widespread application in network monitoring projects, multi-category fiber optic transceiver products have also emerged rapidly, and the product stability has been greatly improved. Cascaded and converged products will be used in future fiber optic network cabling applications The more common.

6、Application of ring network optical fiber transceiver

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

Only one fiber is required to form a ring network, which saves wiring costs. One point fails and does not affect the use of other points.
