Single DWDM channel 56 Gbps 2 km transmission based on injection locked FP laser enabling beyond Tbps intra-DC connection

摘要

By employing an injection locked FP laser (IFP), we successfully achieved 56 Gbps PAM-4 transmission over 2 km SSMF. The IFP laser behaves as a colorless CW source, and 32 DWDM wavelengths are generated by simply connecting the FP laser to different DWDM multiplexer port. These results indicate a beyond Tbps 2km connection solution by densely wavelength multiplexing the IFP transmitter.
