The invention relates to an all-fiber mode converter and a light system. The all-fiber mode converter comprises a mode coupling fiber portion and a fiber portion of a mode peeler which are connected, a light system structure of the all-fiber mode converter comprises an input fiber, a first mode field adapter, an all-fiber mode converter, a second mode field adapter and an output fiber which are sequentially welded to realize mode conversion, a first spreading mode is transmitted from the input fiber through the first mode field adapter to the all-fiber mode converter at the lowest loss rate, and only a second spreading mode exists after the all-fiber mode converter, and the second spreading mode is transmitted through the second mode field adapter to the output fiber at the lowest loss rate for output. The all-fiber mode converter is for fiber mode conversion and further has advantages of easy realization, high conversion efficiency and small conversion noise.
