WDM Optical Access Network for Full-Duplex and Reconfigurable Capacity Assignment Based on PolMUX Technique

Abstract

We present a novel bidirectional WDM-based optical access network featuring reconfigurable capacity assignment. The architecture relies on the PolMUX technique allowing a compact, flexible, and bandwidth-efficient router in addition to source-free ONUs and color-less ONUs for cost/complexity minimization. Moreover, the centralized architecture contemplates remote management and control of polarization. High-quality transmission of digital signals is demonstrated through different routing scenarios where all channels are dynamically assigned in both downlink and uplink directions.

Wavelength division multiplexing laser arrays for applications in optical networking and sensing: Overview and perspectives

“…Multiwavelength lasers have been extensively used in the long-haul, metro, and access networks to provide high channel capacity, broadband wavelength switching and routing, and flexible bandwidth management and provisioning. [36][37][38][39][40][41] Even for relatively shorter distance links such as the optical interconnects in data centers, the optical transceivers (TRXs) need to incorporate multiple light sources to provide the ever-increasing data rates in a reduced module size as well as to meet the requirements of low latency and low power consumption. These applications pave an ideal path for employing WLAs in the optical TRXs.…”

Lasers in Passive Optical Networks and the Activation Process of an End Unit: A Tutorial

“…The bitrate of the first passive optical network was 155 Mbps in the downstream direction. During this time, PONs were innovated in many ways, and the bitrate increased to 100 Gbps [1][2][3][4][5][6][7][8][9]. The evolution of PONs is shown in Figure 1.…”

Optical power dimensioning for a multi‐PON architecture featuring light‐source centralising based on polarisation multiplexing

“…The main goal is to guarantee a suitable QoS level according to the present and short‐term requirements of optical access networks. This architecture is based on the approach proposed in [12], which allows additional studies in derived models in order to evaluate the power requirements in PolMUX‐based CLS systems.…”
