There are varies modulation formats such as ASK, OOK, BPSK, QPSK, DP-QPSK. The DP-QPSK modulation format appears as the best performing 50 Gbit/s modulation format solution with higher transmission efficiency and stronger anti-interference ability. Therefore, this topic has great significance for the study of a test system of DP-QPSK optical transmission. There is hardware and software design of the test system. Hardware design is the basis and prerequisite for the design of the test system, requiring further understanding of the composition of the test system. The software which completes the work of data processing is a crucial part of the whole test system.
