This invention discloses a reliable control method for airborne data bus optical links based on multimode PON. First, a dual-channel OLT module simultaneously sends a terminal data transmission request query command to a designated bus terminal interface on two bus optical connection links. All bus terminal interfaces utilize dual-channel ONU modules, receiving bus data signals simultaneously on both channels. The designated bus terminal interface responds to the terminal data transmission request query command in real time using a determined link of the dual-channel ONU module, and sends the bus data signal it needs to transmit to the line controller on that determined link. The bus controller receives the bus data signal on the link determined by the terminal and forwards the terminal data signal in real time on both bus links. All bus terminal interfaces utilize dual-channel ONU modules, receiving bus data signals simultaneously on both channels, thus achieving deterministic transmission, redundant transmission, and redundant reception of signals transmitted by the bus terminal interfaces.
