CORE GUIDE DEVICE FOR DRAWER TYPE EXCESS LENGTH STORAGE SHELF OF OPTICAL FIBER

摘要

PURPOSE:To prevent kink phenomenon and tangle of fiber part by absorbing slack of optical fiber part which extends between lead section of fiber and drawer by slack absorbing guide face of a guide member which guides optical fiber part. CONSTITUTION:An optical fiber part 18a between a lead section 16 and a drawer 20 is displaced together with the drawer 20 while it is guided by a guide member 24 in accordance with opening and closing of the drawer 20, but a guide face 26 of the guide member 24 is formed in such a way that slack which occurs as the distance between the lead section 16 of fiber and the drawer 20 changes due to travel of the drawer 20 is absorbed. Consequently, slack of the optical fiber part 18a does not occur and kink phenomenon and tangle of the optical fiber part 18a do not occur when the drawer 20 is opened or closed.
