The invention relates to a planar lightwave circuit splitter, in particular to a technique for coupling a planar lightwave circuit splitter chip and fiber array and provides a low-insertion-loss coupling technique. The low-insertion-loss coupling technique comprises an input single fiber (1), the planar lightwave circuit splitter chip (2) and an output optical fiber array (3). The low-insertion-loss coupling technique is characterized in that the input single fiber (1), the planar lightwave circuit splitter chip (2) and the output optical fiber array (3) are integrated. Difference between a chip insertion loss standard value and a finished product insertion loss value is reduced to the largest extent, phenomena of large loss and unstable performance of an automatic monitoring system caused by errors are avoided, and simultaneously production cost is reduced.
