This disclosure provides a method, system, and computer system for measuring bending loss of an optical fiber with an optical time domain reflectometer (OTDR). Generally, the method of the present invention provides OTDR device that measures a one-way OTDR splice loss at a point in the optical fiber. Subsequently, a bend is introduced into the optical fiber and a second one-way OTDR splice loss measurement is performed at the same point in the optical fiber as the first measurement. Thereafter, the bending loss of the optical fiber is determined and related to an approximate cut-off wavelength of the optical fiber.
