The invention discloses a dual fiber connector with partial wave/complex wave, comprising a fiber connector I and an adjustable fiber connector II compared to the fiber connector I; wherein the fiber connector I comprises a partial wave/complex wave component; an output fiber I of the partial wave/complex wave component is connected with the fiber arranged in the fiber connector I as a whole; the output fiber II of the partial wave/complex wave component is connected with the fiber arranged in the fiber connector II as a whole; the input fiber of partial wave/complex wave component is connected with the pigtail on the other end of the fiber connector I as a whole; after the input fiber of partial wave/complex wave component receiving light signal, two light signals with different wave lengths are formulated and output from fiber connector I and the fiber connector II respectively. The fiber connector II is adjustable relative to the fiber connector I, so as to adapt GPON/XGPON light module size of various manufacturers, and satisfy requirements of insertion in place and smooth deblocking, besides, compared to traditional WDM component, the fiber connector has smaller size, lower cost and less insertion loss.
