The invention discloses an optical network wire distribution device which comprises a tray and an intelligent optical network wire distribution structure. The tray is provided with a plurality of first connectors. The intelligent optical network wire distribution structure comprises a plurality of switch-over pieces, an upper cover, a circuit board and a bottom shell. The circuit board is arranged on the upper cover which is arranged on the bottom shell. One end of each switch-over piece is arranged on the bottom shell. The other end of each switch-over piece is inserted into a first connector of the tray, so that the intelligent optical network wire distribution structure is arranged at the tray. According to the optical network wire distribution device, the intelligent optical network wire distribution structure can be arranged to the tray through the switch-over pieces, accordingly, under the situation that the structure of the tray does not need to be transformed and optical fiber transmission service does not need to be stopped, an existing ODN can be transformed into an IODN, and the problems that in the prior art, due to tray transforming, cost is high, and user using is not convenient are solved.
