Description

Multi-system fiber optic near-end machine chassis

technical field

The invention relates to the technical field of mobile communication, in particular to a multi-system optical fiber near-end machine chassis.

Background technique

With the rapid development of information technology, mobile communication has entered the large-scale commercial stage of the fourth generation mobile communication system (4G). At present, many optical fiber near-end machine chassis have been used for too long, which may easily lead to poor heat dissipation and cannot work stably. At present, the method of adding 4G system chassis is basically used to solve the problem of 4G signal coverage. This method has the disadvantages of large volume, relatively difficult installation, low flexibility, and high cost.

The existing multi-system optical fiber near-end machine chassis is connected to the remote machine through the fiber optic module on the front of the chassis. A near-end machine can be installed with up to four fiber optic modules, and each fiber optic module is connected to a fiber optic remote machine. The optical fiber transmission distance is 20 kilometers.

Contents of the invention

In view of the above problems, the technical problem to be solved by the present invention is to provide a multi-system optical fiber near-end machine chassis with reasonable structural design, convenient installation, low cost and beautiful appearance.

The multi-system optical fiber near-end machine chassis of the present invention includes an upper cover, a side plate, a rear panel, a module fixing plate, a front panel, and a lower cover; two side plates are arranged on both sides of the module fixing plate; The rear side of the module fixing plate is provided with a rear panel; the front side of the module fixing plate is provided with a front panel; the upper cover is arranged above the module fixing plate, and the lower cover is arranged At the bottom of the module mounting plate.

The front panel can be fixed with the radio frequency connector to realize the radio frequency connection function of the whole machine.

The rear panel can be fixed with the power connector to realize the power supply function of the whole machine.

The module fixing plate realizes the fixing of the modules inside the chassis, so as to meet the installation requirements of different system modules.

The invention utilizes the chassis module fixing plate to fix the module, and realizes the function of the whole machine through the connection of the front panel and the rear panel. Through the connection between the fiber optic module interface on the front of the chassis and the input interface of the fiber optic splitter, four fiber optic remote machines can be connected using two fiber optic modules, and the fiber optic transmission distance is 20 kilometers.

Beneficial effects of the present invention:

1. Easy installation: no need to add any separate installation holes on the wall or equipment, and can be directly connected to the existing standard 19-inch cabinet;

2. Beautiful appearance: consistent with the standard 19-inch chassis;

3. Small size: Compared with the existing standard chassis, the volume is reduced by 60%;

4. Low cost: Compared with existing equipment, the cost can be reduced by 40%.
