5G and IP downlink broadcast bidirectional channel fusion method and system

The invention discloses a 5G and IP downlink broadcast bidirectional channel fusion method and system. The 5G and IP downlink broadcast two-way channel fusion method comprises the following steps: step S1, arranging an intelligent shunting local side and a 5G optical antenna array local side in a last-stage machine room, so as to receive a 25G IP stream of DLT downlink broadcast through an optical fiber, and further send the 25G IP stream to an IP Tuner, so that the bandwidth of a room accessed to a residence reaches a 10-gigabit level; and S2, a passive optical fiber distribution network is laid between the last-stage machine room and the rooms of the residences, and optical splitters are respectively arranged on an uplink and a downlink of the passive optical fiber distribution network, so that the bandwidth accessed to the rooms of each residence reaches a 10-gigabit level. The 5G and IP misfire broadcast two-way channel fusion method and system disclosed by the invention have the beneficial effects that t
