With digital communication , optical fiber communication and technology development , there is a growing emphasis on the error performance of the channel . In the high - speed optical communication systems , the bit error is not ideal due to channel interference and noise , so that the receiving end of the symbol judgment error occurs , so that the transmission quality of the information to produce damage caused . BER tester is the basic instrument for assessing the transmission performance of the system . The burst mode data transmission mode is more and more applications in a digital communication system . In a passive optical network (PON) system , for the uplink signal for the burst characteristics of the signal need to use high - speed burst error detector to measure the performance of the system as a whole . LabVIEW is a program development environment based G language ( graphical programming language) developed by the United States NI . C and BASIC language text-based LabVIEW program is a block diagram form as much as possible to take advantage of the technical staff , engineers familiar with the terminology , the concept of the icon . LabVIEW is an end-user - oriented tools that can enhance the user 's ability to build their own engineering systems and use it to carry out the principles of research, design, test , can greatly improve the work efficiency . Burst BERT features and characteristics of the LabVIEW program , the sudden BERT host computer design method based on LabVIEW interface ( version 2.0 ) . Based on LabVIEW to create interactive interface between a BERT user . Do a whole burst BERT LabVIEW interface , detailed description and analysis of the function of each module in LabVIEW program flow chart , the communication between the control platforms and PC, BERT , and finally to save the test results in within the document . The test data and results of performance evaluation shows that the approach is feasible .
