Abstract

We present a coherent-PON employing partial overlap of downstream/upstream Nyquist spectra, allowing bi-directional operation and enhanced spectral efficiency (2x120Gb/s@50GHz). Additionally, frequency shifting of Nyquist bands from the carrier allowed reduced RBS and dynamic SRS.

Abstract

We experimentally analyze the required guard band of coherent optical UDWDM networks transporting 16×1.25 Gb/s - QPSK at 3.125 GHz frequency grid to coexist with Video and 10G - NRZ transmissions. Using simple DSP based ONU, guard bands of only 0.8-1.6 nm are achieved.

Abstract

We develop a model for simulation of spatial-temporal distribution of photons and carriers in RSOA for downstream optical pulses at 40 and 100 Gb/s, which demonstrates that signal broadening generates CW component of output signal.
