Abstract
A fusion splicing device according to an embodiment is a fusion splicing device of an optical fiber performing fusion-splicing by position-aligning the optical fiber that is a splicing target in a V-shaped groove. The fusion splicing device includes a microscope receiving light from a light source and passing through an optical fiber mounted on a V-shaped groove to obtain luminance information, a V-shaped groove driving unit moving the V-shaped groove, a storage unit storing a position of the V-shaped groove at which the microscope is focused, and an identification unit identifying the optical fiber. The position of the microscope is fixed. The V-shaped groove driving unit moves the V-shaped groove to a position stored in the storage unit. The identification unit identifies the optical fiber moved to the position.
