Abstract :
An optical time domain reflectometer(OTDR) using appropriate encoding light pulses as probe signals can has much better performance than conventional OTDR , for example, improve the measure dynamic range but not reduce the resolution, reduce the required measurement time and so on. This paper present application study of one zero correlation window complementary coded sequence in OTDR, discussed the theoretical foundation of this method and introduced the method to change bipolar codes to unipolar codes, shown the Matlab simulation results at last.
