Abstract
PURPOSE:To enable to perform a steady mode excitation, a high-precise measurement, and a non-destructive system measurement of an optical fiber to be measured, by using an optical fiber, whose core size is smaller than that of the optical fiber to be measured, as an exciter. CONSTITUTION:Light from a light source 1 is caused to enter an exciter consisting of a small-sized core optical fiber 2, light emitted from the small-sized core optical fiber 2 is caused to enter an optical fiber 3 to be measured. The length and core size of the exciter are selected so that a steady mode distribution can be obtained, and an output light power from the small-sized core fiber 2 is measured as an input light power to the optical fiber 3 to be measured to measure the photo loss of the optical fiber 3 by finding a difference between the input light power and an output light power from the optical fiber 3 to be measured. Once an incident light power to the optical fiber 3 to be measured is measured, it eliminates the need to measure the incident light power each time the optical fiber to be measured is replaced, but only an emitting light power may be measured.
