This paper mainly introduces the composition and key technologies of the 40 Gbit/s RZ-DQPSK transponder module and presents a rational experimental scheme for the control of its transmitter and receiver ends.In addition,it tests and verifies the design scheme by using eye diagram,constellation and OSNR,which shows that the signal has an excellent eye diagram and the OSNR is 12.3 dB.The results indicate that the optical module designed in this scheme satisfies the relevant international standards,applicable in the field of optical communications.
