25Gbps and 40Gbps Symmetric PON Using Legacy 10G-Class Optics and Centralized ADC/DAC & DSP
01 January 2016
A DSP enabled NG-PON scheme has been demonstrated carrying symmetric downlink/uplink 25Gbps PAM4/DB-NRZ and 40Gbs PAM8/DB-PAM4 using 10GHz optics, costly devices like ADC/DAC/DSP have all been centralized in OLT with ONUs sustaining simple and compact.
