Single channel 112Gbit/sec PAM4 at 56Gbaud with digital signal processing for data centers applications. Academic Article uri icon


  • 112Gbit/sec DSP-based single channel transmission of PAM4 at 56Gbaud over 15GHz of effective analog bandwidth is experimentally demonstrated. The DSP enables use of mature 25G optoelectronics for 2-10km datacenter intra-connections, and 8Tbit/sec over 80km interconnections between data centers.
