A heating device for heating an optical fiber reinforcing member includes fiber holders to hold optical fibers covered with the reinforcing member at a fusion-spliced portion, a heater to heat the reinforcing member, a power supply unit to apply a voltage to the heater, and a controller to control the application of a voltage from the power supply unit to the heater. The controller includes a detecting unit that detects a parameter for determining the amount of heat generation of the heater, a storage unit that stores a plurality of heating conditions that vary depending on the parameter value, and a condition instruction unit that selects any of the plurality of heating conditions in accordance with the parameter value detected by the detecting unit and instructs the power supply unit to apply a voltage to the heater on the basis of the selected heating condition.
Provided is an easily-identifiable connector-equipped optical fiber cord (1). A connector (10) of the connector-equipped optical fiber cord (1) comprises a ferrule (7), a housing (20), a light emitting member (40), and a boot (50) which is attached to the rear end part of the housing (20) from the rear side thereof and covers at least a portion of the light emitting member (40). The housing (20) further comprises a receiving part (31) which opens to the rear, is covered by the boot (50), and supports a plate-shaped member (42). A wire (4) and the light emitting member (41) are in conductive communication with each other via the plate-shaped member (42).
Provided is a production method for a catheter for an optical coherence tomograph (OCT); the production method can shorten work time, suppress production costs, and reduce breakage of a melt fusion connection part between short optical fibers and interior body-side optical fibers. Also provided is an OCT catheter. An OCT catheter (1A) is provided with an interior body (10) in which optical fibers are embedded and which is inserted into the human body, a metal tube (20) which guides the interior body (10), and an optical connector (30). The optical connector (30) has a ferrule assembly that includes short optical fibers and a ferrule which is fixed to one end of the short optical fibers, and the optical connector is connected to a rotary joint of the OCT. Positioned in the metal tube (20) is a melt fusion connection part formed by fusing together the other end of the short optical fibers and one end of the optical fibers embedded in the interior body (10).
