Abstract: With phase-sensitive optical time-domain reflectometry (Φ-OTDR), an optic fiber can be used as a distributed vibration sensor to perceive the external disturbance along the fiber through the ...
The algorithm for OTDR measurement is implemented on a Altera’s Cyclone FPGA .This embedded FSM machine generates a logic pulse of varying width from 10ns to 10us to analyze fiber optic cable from 10 ...
