Abstract
In order to real-time get optical power signal transmitted in optical fiber,a new high-speed acquisition system is designed.Based on LabVIEW virtual instrument programming language and USB technique, the system combines an optical receiver with an USB DAQ card USB-M6251 of NI Company.It overcomes the disadvantages of the traditional system, such as low sampling rate,single channel display,insufficient man machine interface function and poor portability, and realizes the real-time acquisition,display and storage of optical-power signal in dual channels with sampling parameter controllable.Experiments prove that the optical power signal acquisition system is reliable and practical,and it provides a good man machine interface. It can be used to monitor the optical power signal in various optical fiber communication systems.
