Abstract:

The bandwidth efficiency is an important design parameter for the next-generation passive optical network stage 2 (NG-PON2). In this paper, two optical line terminal (OLT) designs based on polarization split state are proposed for NG-PON2. The first method doubles the data rate per wavelength by separate amplitude modulation of both polarization states. Whereas in the second method, differential phase-shift keying (DPSK) modulates another data on each amplitude-modulated state, this approach increases data rate per wavelength by four-folds. The proposed system provides NG-PON2 access while coexisting with a gigabit passive optical network (GPON) and 10 GPON (XG-PON). The proposed system design serves 1024 NG-PON2 next-generation passive optical network stage 2 (ONUs), 128 GPON ONUs, and 128 XG-PON ONUs. The transmission performance of the system is verified by evaluating the (BER) for varied received power. The acceptable bit error rate level of less than 10−9 is considered in this work.
