Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] figure 1 It shows the power supply scheme of the broadband distribution system in some embodiments, which is remotely powered by the data exchange center (DEC) 2 to the data remote unit (DRU) 3a-3d, therefore, only the multi-service access center 1 and the data exchange Center 2 is plugged directly into AC or DC power.

[0021] Such as figure 1 As shown, the specific power supply method includes: setting a first power supply module 11 in the multi-service access center 1, and supplying the multi-service access center 1 (including the main monitoring module 13 and The digital processing module 14) supplies power. On the other hand, a second power supply module 21 is set in the data exchange center 2, and the power introduced from the outside is converted by the second power supply module 21 to supply power to the data exchange center 2 itself (...

Abstract

A power supply method of a broadband distribution system comprises arranging a first power supply module in a multi-service data access center; supplying power for the multi-service data access center after an external power supply is converted; arranging a second power supply module in a data exchange center; supplying power for the data exchange center after an external power supply is converted; transmitting the converted electric energy to data remote units along with signals and supplying power for the data remote units, wherein the data remote units are connected with the data exchange center. According to the power supply method of the broadband distribution system, the remote centralized power supply is achieved and accordingly the problem that the power supply of the data remote units is difficult is solved and a great convenience is brought to the power consumption management due to the centralized power supply.

Description

technical field [0001] The invention relates to a broadband distribution system, more specifically, to a power supply method for a broadband distribution system. Background technique [0002] Intelligent wide-band distribution system (IWDS) is divided into three parts: multi-service access center (multi-service data access center, MSAC), data exchange center (data exchange center, DEC) and remote data unit (data remote unit, DRU), the three are set in different places, the data exchange center can be directly connected to the multi-service access center through optical fiber, or multiple data exchange centers can be connected to the multi-service access center after cascading, and the data pull The remote unit is connected to the data switching center through an optical fiber or a network cable. Since the remote data unit is installed at the user end, such as in a building or beside a road, it is difficult to supply power. Even if it is installed in a building, the powe...
