Abstract :
Employing DSP technology is an attractive way to enhance standardized 10-Gbps per wavelength PONs toward the converged optical-wireless network. For TDM-based co-existence of digital coherent PON and existing PONs, burst mode coherent receivers for uplink and hierarchical modulation for downlink are introduced.
