Abstract :
We demonstrate SNR improvement of OTDR using simplex codes by experiment, for the first time. For this, we proposed a practical algorithm and derived detailed equations. An in-house OTDR board was developed to verify the proposed algorithm, and the experimental results showed excellent agreement with theory. In addition, we analyzed the SNR variation of the simplex code OTDR, caused by band-limited receiver characteristics.
