Abstract

According to the high-speed, continuous data acquisition of OTDR applied research based on FPGA. The data acquisition system will help improve the OTDR (Optical Time Domain Reflectometer) signal to noise ratio, stability, reduce inter-code interference, Especially the implementation of the signal high-speed, continuous data processing capabilities.The program is the use of Altera Cyclone II series FPGA EP2C70F896C as the core processing chip,Full use of FPGA internal logic logic unit. Design of various modules to form OTDR (Optical Time Domain Reflectometer) high-speed, continuous system schematic.To achieve OTDR data acquisition signal to noise ratio, stability, inter-symbol interference and improve certain improvement.
