preparing an optical fiber protective unit comprising
a reticulated tube, and
a tubular member inserted through the reticulated tube that is in a state folded in a longitudinal direction, such that the reticulated tube is disposed in a folded state on an outer periphery of the tubular member;
inserting a plurality of optical fibers into the tubular member, and thereby inserting the plurality of optical fibers into the reticulated tube in the folded state;
pulling out an end part of the reticulated tube from the tubular member; and
extending the folded-state reticulated tube in the longitudinal direction, to thereby insert the plurality of optical fibers into the reticulated tube in an extended state.
