A method for compensating an originating signal error of an optical time domain reflectometer, comprising: detecting an actual signal sequence of a PN sequence sent by a transmitter to a detected optical fibre and an actual signal sequence of an optical signal reflected back by the detected optical fibre and received by a receiver (101);according to the actual signal sequence of the PN sequence, a theoretical signal sequence of the PN sequence and an optical fibre attenuation curve function obtained by an adjacent last iterative computation, computing to obtain a compensation value of the attenuated optical signal in a reflection process of the detected optical fibre (102);according to the actual signal sequence of the optical signal, the compensation value and the theoretical signal sequence of the PN sequence, computing an optical fibre attenuation curve function obtained through this iteration (103); and when it is determined that the optical fibre attenuation curve function obtained through this iteration satisfies a set condition, according to the optical fibre attenuation curve function obtained through this iteration, determining the performance of the detected optical fibre (104).Also provided is an apparatus for compensating an originating signal error of an optical time domain reflectometer.
