PURPOSE:To freely adjust the length of an optical fiber for leader line which connects an outdoor installation optical cable to a communication material. CONSTITUTION:This module is provided with a drum 2 across which an optical fiber 1 is wound, a side peripheral wall 3 which regulates the bulge of the optical fiber 1, and collars 4, 5 which regulate the extraction of the optical fiber 1, and the upper collar 4 is provided in such a way that it can be rotated relatively freely. A leading port 6 for the optical fiber 1 is provided at the collar 4, and the leading and rewinding of the optical fiber 1 can be performed via the leading port 6 by rotating the collar 4 in desired forward and backward directions. |
