In recent years, the growth demand of information transmission has promoted the development of communication technology. Many modulation methods are used in many fields, such as QPSK and OFDM, which are used in long-distance communication. In this thesis, I discussed the PAM-4, which can be used in inter-data center (< 80km) links due to its better performance and lower cost. Then I tested one channel 4 × 50Gbps PAM-4 system and eight channels 4 × 50Gbps PAM-4 system with varying degrees of gain of optical amplifier and length of DCF. Finally, I discussed the performance of the two designs and figured out the factors that affect the transmission system.
