OPTICAL FIBER HOLDER AND OPTICAL FIBER FUSION-CONNECTING DEVICE

摘要

Provided is an optical fiber holder capable of holding optical fibers while suppressing damage to bare fibers even when the ratio of bare fiber exposure differs therebetween. Also provided is an optical fiber fusion-connecting device comprising said optical fiber holder. The optical fiber fusion-connecting device (1) comprises the optical fiber holder (3) for holding optical fibers. The optical fiber holder (3) has a base (10), a lid (20), and a connecting section (30). The base (10) has a mounting surface (11) whereon the optical fiber (F) is mounted in the longitudinal direction thereof. The lid (20) has pressing sections (23a-23c) for pressing the optical fiber (F) mounted on the mounting surface (11) against the mounting surface (11). The connecting section (30) is connected so as to be capable of opening and closing the lid (20) in relation to the base (10), and so as to be movable along the longitudinal direction of the base (10).
