摘要

The application of spread spectrum technology in optical time domain reflectometer (OTDR) is studied. And an innovative method for direct using bipolar spreading code in OTDR is proposed by using optical differential phase-shift keying (DPSK). The theoretical analysis and simulation of the method are carried out, and the simulation results are in good agreement with the theoretical analysis, verifying the feasibility of the method.
