The utility model relates to a low-insertion-loss multi-optical-fiber-head collimator which comprises an optical fiber array, a first fixing block, a second fixing block, a capillary tube, a micro lens and an outer sleeve. The capillary tube and the micro lens are axially fixed in the shaft hole of the outer sleeve at intervals; the first fixing block is provided with a plurality of first micropores distributed in an array mode. The second fixing block is provided with a plurality of second micropores distributed in an array mode. And each optical fiber in the optical fiber array firstly passes through the corresponding first micro hole in the first fixing block, then passes through the corresponding second micro hole in the second fixing block, finally passes through the capillary tube and extends into the outer sleeve. According to the utility model, by introducing the extra micropore array, the back intercept of each optical fiber or each row of optical fibers can be independently adjusted, and the problem
