摘要：Included are monitoring a loss value of the optical fiber with respect topropagation light having a wavelength at or in the vicinity of 1714 nm after the opticalfiber is exposed to deuterium; and ending the exposure of the optical fiber to the
deuterium when a change quantity of the loss value has exceeded a predetermined value.
The monitoring of the loss value is pursued by, while exposing the optical fiber to anatmosphere that contains deuterium, causing propagation light having a wavelength at orin the vicinity of 1714 nm to be incident from one end of the optical fiber, monitoring thepropagation light emitted from the other end of the optical fiber, and measuring a lossvalue of the optical fiber. According to this, it is possible to manufacture an optical fiberhaving an excellent hydrogen resistance characteristic assuredly and at low cost.
