The power conversion module 3 is arranged in the box 1, and a power supply end of the power conversion module 3 is used for connecting a power grid 100. A first power supply end of the power conversion module 3 is connected with a power supply end of the OLT device 2. The storage power module 4 is arranged in the box 1, and a power supply end of the storage power module 4 is connected with a second power supply end of the power conversion module 3. A first power supply end of the storage power module 4 is connected with the power supply end of the OLT device 2.

[0028] It can be understood that, since the first power supply end of the power conversion module 3 and the first power supply end of the storage power module 4 are respectively connected with the power supply end of the OLT device 2, the power conversion module 3 can convert the power of the external power grid 100 and then transmit the power to the OLT device 2, and the storage power module 4 can transmit the stored power to the OLT device 2, so as to meet the stable power demand of the OLT device 2. Moreover, the OLT device 2, the power conversion module 3 and the storage power module 4 are arranged in the box 1, so that the communication device is more convenient to carry and use, and thus the OLT device 2 can be quickly deployed and connected in the field in the face of disaster scenarios. Therefore, through the integrated design of the OLT device 2, the power conversion module 3 and the storage power module 4, the communication device can use the OLT device 2 to realize temporary communication between the first uplink communication network 200, the second uplink communication network 300 and the downlink communication network, so as to reduce the communication interruption time and reduce the economic loss.

[0029] It should be noted that the box 1 is used for realizing the integrated arrangement and protection of the OLT device 2, the power conversion module 3 and the storage power module 4. The specific type of the box 1 can be set according to actual needs, and no limitation is made herein.

[0030] The OLT device 2 belongs to a local device, which can be connected with a front-end (convergence layer) switch through a network cable and be converted into an optical signal.

[0034] In scenarios where mains power is available, the power conversion module 3 converts the mains power to supply power to the OLT device 2 and the energy storage module 4. While the OLT device 2 operates stably, the energy storage module 4 charges. In scenarios where there is no mains power, the energy storage module 4 discharges power to the OLT device 2 to provide long-term backup power. Therefore, through the cooperation between the power conversion module 3 and the energy storage module 4, the problem of not being able to provide external power in some scenarios can be avoided, effectively improving emergency endurance.
