- 초록
- Design and implementation of a correlation-based OTDR (C-OTDR) transceiver is discussed. The C-OTDR uses a high-power low noise avalanche photo diode detector and transimpedance and variable gain amplifiers with correlation-based OTDR FPGA modem. A dynamic range of approximately 38 dB is demonstrated. Spatial resolution of 5 meter and event dead zone of 10 meter are achieved.
