Near-end node, far-end node, and indoor distribution system

The utility model provides a near-end node, a far-end node, and an indoor distribution system, wherein the far-end node includes a far-end integrated module. The outside of the far-end integrated module is provided with a dual-polarized indoor distribution antenna, and the inside of the far-end integrated module is provided with a first combining and separating module, a second combining and separating module, a far-end first frequency converter, and a far-end second frequency converter, wherein the first combining and separating module is connected with a main feeder, the far-end first frequency converter and the far-end second frequency converter are connected with the first combining and separating module respectively via lines, the second combining and separating module is connected with the far-end second frequency converter and the first combining and separating module respectively via the lines, and the dual-polarized indoor distribution antenna is connected with the far-end first frequency converter and the second combining and separating module respectively via the lines. The near-end node, the far-end node, and indoor distribution system reduce the power consumption, lower the failure rate, greatly reduce the construction cost, and shorten the engineering construction period.
