[0002] With economic development and population growth, the demand for communication networks is also increasing. To fully realize the potential of 5G communication technology, it is necessary to build communication base stations on a large scale to improve network coverage, enhance network capacity, and improve network speed and reliability.

[0003] As an integrated power supply for base stations, it incorporates multiple functions, including rectification, conversion, control, and protection. The base station AC / DC power supply converts AC power to DC, providing a stable power supply for base station equipment. Conventional base station AC / DC power supplies are standalone components. Communication AC / DC power supplies lack fiber optic wiring capabilities, requiring a separate fiber splitter box to meet base station construction requirements. Existing photovoltaic boxes that integrate both the AC / DC power supply and ODF functionality house the power system within the box, while the fiber optic wiring unit is mounted on a removable mounting plate. This integrates the photovoltaic and optical components within the box. However, maintenance on the power system requires opening the box door and then removing or removing the mounting plate, which can interfere with each other during maintenance. Proper operation of the power system requires ample heat dissipation space within the box. Consequently, base station equipment is typically large, making it difficult to simultaneously provide waterproof sealing and ventilation, making it difficult to operate in high-temperature outdoor environments.
