The invention relates to a multifunctional optical fiber melting-matching tray which comprises a rear cover plate, a front cover plate, a melting-welding chip, a melting-welding disc, a wrapping post, a terminal disc and a wire sleeve. The front cover plate is installed on one side of the rear cover plate, the melting-welding chip is installed on the melting-welding disc, an opening hole is formed in the melting-welding disc, the wrapping post is a circle with a wrapping lug, the wrapping lug penetrates through the opening hole in the melting-welding disc, the wrapping post is installed on the terminal disc, and the rear cover plate, the melting-welding chip, the melting-welding disc, the wrapping post and the terminal disc are sequentially arranged in the sequence from top to bottom. The wire sleeve is installed on the terminal disc, and the front cover plate is installed on the rear cover plate through a rotating shaft. The multifunctional optical fiber melting-matching tray can meet belt-shaped or bundle-shaped tail fibers of a plurality of adapters and movable connectors matched with the adapters and meet left-and-right fiber outlet of wiring, box-type optical branching devices below 1:32 and 2:32 can be installed, according to the multifunctional optical fiber melting-matching tray, varieties of trays are reduced, the period of goods preparation is shortened, and the management cost is reduced.
