Abstract
This reinforcement device includes: a first heater (9A) on which a fusion-spliced section of an optical fiber covered with a protective member is disposed and which heats a central portion of the protective member at a first temperature (T1); second heaters (9B) which are respectively provided on both sides of the first heater (9A) along a longitudinal direction of the optical fiber and respectively heat both end portions of the protective member at a second temperature (T2); and a CPU (14) which performs energization control for heating each of the first heater (9A) and the second heaters (9B), wherein the CPU (14) makes an energizing time of the first heater (9A) and an energizing time of each of the second heaters (9B) at least partially overlap.
