چکیده

We discuss the compatibility between reflective PON architectures and the recently defined ITU-T G.989.1 TWDM-PON. Focusing on the upstream, we experimentally demonstrate that, by using burst-mode coherent detection at OLT, reflective PON can achieve the specification target set for TWDM-PON, without requiring precise wavelength accuracy at ONU. Compared to the companion ECOC 2013 paper, we investigate on the differential optical path loss (DOPL) issue, proposing a simple SOA gain control algorithm to achieve reliable transmission for DOPL up to 17 dB.

Survivable architectures for time and wavelength division multiplexed passive optical networks

The increased network reach and customer base of next-generation time and wavelength division multiplexed PON (TWDM-PONs) have necessitated rapid fault detection and subsequent restoration of services to its users. However, direct application of existing solutions for conventional PONs to TWDMPONs is unsuitable as these schemes rely on the loss of signal (LOS) of upstream transmissions to trigg...

Energy Efficient Dynamic Wavelength and Bandwidth Allocation for TWDM PON

This paper proposes a new dynamic bandwidth and bandwidth allocation (DWBA) algorithm for energy saving in time and wavelength division multiplexing passive optical networks (TWDM PONs). Decreasing the number of active upstream wavelengths, the proposed algorithm not only saves power but also provides good efficiency for TWDM PON systems. Using simulations, we evaluate performance of the propos...
