Abstract

Next generation optical access network needs more flexibility and programmable service provisioning to meet the future effective network operation and maintenance requirements. We propose a novel full-service software-defined Flex PON solution that has three innovative features: (a) DSP-enabled flexible transceiver and flexible link, (b) OLT side access network resource virtualization, and (c) software-defined programmable network functions and resource scheduling. We also experimentally demonstrate the three DSP-enabled flexible transceiver/link application scenarios. The first case uses single OFDM-based RF band that delivers 1.6/3.22/4.03/4.7 Gb/s to different ONUs with QPSK, 16QAM, 32QAM, or 64QAM modulations for achieving different optical power budgets of 36, 32, 30, or 28 dB, respectively. The second case uses dual RF bands to deliver wireless/video/data services in different bands dynamically, realizing a service-programmable capability based on the real network deployment requirements and link conditions. The third case demonstrates a multiband wireless signal transmission in a flexible frequency relocation manner to reuse the PON infrastructure.
