ABSTRACT:
This G-PON network testing apparatus composes a network by connecting between an OLT, ONU or ONT by a optical fiber. This testing apparatus stores testing items and code numbers in a storing section by correlating them from each other. It obtains data receiving time and transmits the data to a delay buffer A when no test is implemented and generates testing data in which a code number is added to the data when a test is implemented. Then, this testing apparatus extracts the code number from the generated testing data to implement the testing item and obtains time when the testing item is finished. Then, it calculates a test time necessary for implementing the test from this time and the data receiving time and reads the data transmitted to the delay buffer A after an elapsed of the calculated test time.
