Abstract
A method for compensating for a signal error at a transmit end of an optical time domain reflectometer is provided. The method includes: detecting an actual signal sequence of a PN sequence sent by a transmitter to a measured optical fiber and an actual signal sequence of an optical signal and reflected back by the measured optical fiber and received by a receiver; obtaining a compensation value of the optical signal that attenuates in a process in which the optical signal is reflected by the measured optical fiber; computing an optical fiber attenuation curve function obtained through a current iteration; and determining, when determining that the optical fiber attenuation curve function obtained through the current iteration satisfies a given condition, performance of the measured optical fiber according to the optical fiber attenuation curve function obtained through the current iteration.
