The Design of Optical Fiber Fault Locator Based on FPGA

Abstract

This paper presents in detail optical fiber fault locator's operation principle, fabrication technology and application. A prototype apparatus has been fabricated, which reaches commercial standard, resolves the problem of traditional OTDR price expensive and the operation complicated . All component s including optical devices, electronic devices and data measurement are demonstrated. Furthermore, through measuring the fiber sample, the function and measurement efficiency of this apparatus is analyzed.
