TL;DR: An asymmetric bidirectional optical wireless communication (B-OWC) system using optical fibers as the transmitter and receiver and capable of wavelength switching is proposed for next generation passive optical network stage two (NG-PON2) extension to home area network (HAN).
Abstract: An asymmetric bidirectional optical wireless communication (B-OWC) system using optical fibers as the transmitter and receiver and capable of wavelength switching is proposed for next generation passive optical network stage two (NG-PON2) extension to home area network (HAN), without optical/electrical (O/E) and electrical/optical (E/O) conversions, which is based on a transmissive "floating" pixel size one-dimensional (1D) liquid crystal spatial light modulator (LC-SLM) at the access node (AN) and a modulated retroreflector (MRR) at the terminal user (TU). The utilization of a reflective grating element and a low-cost LC-SLM in the AN offers a high flexibility of beam steering and wavelength selection in the scenario of B-OWC. Instead of a light source used at conventional TU, a MRR was employed at a TU in order to improve the problems of the power consumptions, alignment difficulties, wavelength contentions, and cost of the TUs. Downlink and uplink data transmissions at a link speed over 2.5 Gbits/s, using wavelengths between 1590∼1603nm and 1524∼1544nm, respectively, corresponding to the downlink and uplink wavelengths specified by the NG-PON2 standard, have been experimentally demonstrated successfully, with quality factors (Q-factors) beyond the forward error correction limit (Q-factor=16.9dB, bit error rate=10-12).

TL;DR: In this paper, a simulation over B2B configuration and fiber based optimization is performed for maximum reach, provided nonlinear propagation of optical signal with amplification over uncompensated link.
Abstract: This paper investigates downstream transmission of 112 Gb/s coherent next generation-passive optical network II (NG-PON2) over multiple end users by deploying different polarization multiplexed phase shift formats. Here, a simulation over B2B configuration and fiber based optimization is performed for maximum reach, provided nonlinear propagation of optical signal with amplification over uncompensated link. The analytical behaviour of the proposed NG-PON2 is numerically measured in terms of receiver sensitivity, bit error rate, optical signal to noise ratio, error vector magnitude and constellation diagram with acceptable performance. Exceptionally good power budget is also calculated for d…
