TL;DR: In this article, an ultradense WDM-PON with only 6.25 GHz channel spacing is implemented with conventional DFB lasers, for a splitter-based PON infrastructure with 256 ONUs.

TL;DR: In this paper, a direct phase modulating a low-cost distributed feedback laser is presented for user transmitter in ultra-dense wavelength division multiplexing passive optical networks, consisting of a simple RC network, which equalizes the phase response.

TL;DR: This article presents ACCORDANCE, a novel optical access network architecture based on OFDMA technology and applied on a PON topology that aims to outperform existing PON solutions in terms of total capacity, bandwidth allocation flexibility, number of users, and network reach.

TL;DR: In this paper, the statistical orthogonal frequency division multiplexing passive optical network (OFDM-PON) concept with multiband optical network units (ONUs) is experimentally tested with two users and an optical line terminal at 2.5/5 Gb/s total effective capacity with binary phase shift keying (BPSK)/quadrature phase-shift keying modulation.

TL;DR: In this article, a centralized polarization scrambling and single-PD coherent ONU Rx system was proposed and tested with two Tx and direct-phase modulated DFBs, and a sensitivity at BER=10-3 of ×45dBm with 7.5GHz channel spacing was achieved.
