PROBLEM TO BE SOLVED: To provide a method, a system and a computer system for measuring a bending loss of an optical fiber by an optical time domain reflexometer(OTDR). SOLUTION: In this method, an OTDR device for measuring a one-way OTDR connection loss at one point in the optical fiber is generally provided. Successively, a bending is introduced into the optical fiber, and the second one-way OTDR connection loss measurement is performed at the same point as the first measurement. Thereafter, the bending loss of the optical fiber is determined and associated with an approximate cutoff wavelength of the optical fiber.
