Design and Implementation Analysis of the Integrated Monitoring and Management System Based on OTDR
OTDR is the most important instrument in fiber optic measurement,which is widely used in the measure-ment,construction,maintenance and acceptance of fiber optic cable projects.It is the most frequently used field in-strument in optical fiber system,and is vividly known as the"multimenter"in optical communication.In order to get rid of the drawbacks of traditional OTDR,such as relatively expensive price and inability to carry out real-time moni-toring,a new scheme of OTDR based on PC which is designed by virtual instrument technology is explicitly put for-ward.It uses PC-DAQ system structure and consists of data acquisition card and data processing method.It can real-ize real-time collection,storage and analysis of optical fiber backtransmission data signals,and has certain engi-neering practical value.
