Description

Power supply side plug-in panel ONU

Technical Field

The utility model relates to the technical field of optical fiber communication, in particular to a panel ONU with a power supply side inserted.

Background

The optical fiber to desktop (Fiber To The Desktop, FTTD) uses optical fibers to replace traditional network wires (such as class 6 wires) to extend the network to the user terminal, so that the user terminal realizes network access through the optical fibers in the whole process. FTTD access technology is a network technology that has emerged in recent years and has been widely used abroad. With the continuous decrease in prices of optical fibers and optical fiber access devices, FTTDs are also becoming increasingly widely used in China, such as hospitals, government buildings, commercial buildings, schools, hotels, and the like.

The optical network unit (Optical Network Unit, ONU) belongs to user side equipment of the access terminal and is mainly used for providing various UNI interfaces such as telephone, data communication, images and the like for users. The prior panel ONU mainly comprises an ONU circuit board, a power module and a protective shell, and a plurality of panel ONU in the prior market are arranged as a whole, namely the ONU circuit board and the power module in the panel ONU are integrated into a whole. Therefore, although the ONU circuit board and the power module can be conveniently arranged in the shell to a certain extent, the ONU circuit board and the power module are integrated into a whole, which is not beneficial to the maintenance work of a panel ONU by staff. When one of the ONU circuit board and the power supply component malfunctions and needs to be replaced, the other component can be replaced together even if not damaged, thus wasting resources and increasing the maintenance cost of the panel ONU. To reduce maintenance costs of panel ONUs, some skilled in the art have begun to develop separate panel ONUs, i.e., ONU circuit boards that are separate from power components.

For example, the prior art discloses an ONU for FTTD comprising a panel and a bottom box arranged opposite to each other, at least one of the panel and the bottom box being of a channel-like structure, forming an accommodation space therebetween; an inner plate, a photoelectric conversion plate and a power panel are sequentially arranged in the accommodating space; the bottom box comprises a rectangular groove-shaped structure arranged along the first depth direction and a convex multi-stage trapezoid structure arranged along the second depth direction, the inner plate is embedded into the rectangular groove-shaped structure, and a cavity capable of accommodating the photoelectric conversion plate and the power supply plate is arranged in the convex multi-stage trapezoid structure; and the optical transceiver module interface component of the photoelectric conversion plate is arranged in parallel with one side of the bottom box, so that the optical fiber can be conveniently and directly spliced with the optical transceiver module interface component through the connector. In the technical scheme of the disclosure, through integrating the inner plate, the photoelectric conversion plate and the power panel in the accommodating space formed by the panel and the bottom box, the micro cable is directly spliced with the optical transceiver module interface component through the optical fiber connector, and the optical fiber is prevented from being exposed. Meanwhile, the photoelectric conversion board and the power panel in the technical scheme can be arranged in a layered manner or integrated on one PCB (printed circuit board) during design. When the photoelectric conversion board and the power supply board are integrated together, although the convenience of installation can be increased to some extent, waste of resources is easily caused at the time of maintenance in the following. Meanwhile, in order to avoid the damage of the circuit board or the power board caused by shaking, the circuit board and the power board are generally tightly arranged in the bottom box, when the power board is arranged in the accommodating space, and the photoelectric conversion boards are layered and stacked on the power board, when the power board is maintained or replaced by a worker, the power board can be taken out only after the photoelectric conversion board arranged on the power board is taken out, so that the maintenance difficulty of the worker is increased, and the working efficiency of the maintainer is reduced.
