TL;DR: Novel no-guard-interval OFDM with frequency domain equalization is proposed and shown to offer excellent long-haul transport with capacity well above 10 Tb/s.
Abstract: Digital signal processing technologies are key enablers for realizing high-capacity Optical Transport Network based on over 100 Gb/s and above channels. Novel no-guard-interval OFDM with frequency domain equalization is proposed and shown to offer excellent long-haul transport with capacity well above 10 Tb/s.

TL;DR: In this article, a highly scalable access architecture achieving high density and featuring resiliency, centralized light-generation control, remote amplification, and colorless optical network unit with reflective semiconductor optical amplifier (RSOA) for upstream modulation is presented and experimentally demonstrated.
Abstract: Feature Issue on Passive Optical Network Architectures and TechnologiesA highly scalable access architecture achieving high density and featuring resiliency, centralized light-generation control, remote amplification, and colorless optical network unit with reflective semiconductor optical amplifier (RSOA) for upstream modulation is presented and experimentally demonstrated. It is based on a user-single-fiber completely passive outside plant and provides broadband connections to >1000 users distributed along large distances. It is believed to represent an intermediate step toward metro-access convergence and offers flexible configurations covering high- and low-density population areas.

TL;DR: Some of the key OAM-related issues include optical path realization technologies, optical path accommodation design problems, a newly proposed optical transport network layer architecture, and the optical transport module for the network node interface.
Abstract: The optical path concept was proposed to realize ubiquitous B-ISDN. It can make quantum leaps in both transmission capacity and cross-connect throughput simultaneously by exploiting WDM (wavelength division multiplexing) transmission and the wavelength routing capabilities of paths. Since the optical path is a new concept, new operation and management (OAM) systems and related technologies need to be developed before it can be fully utilized. This article discusses some of the key OAM-related issues and identifies the technical points necessary for future developments. The issues include optical path realization technologies, optical path accommodation design problems, a newly proposed optical transport network layer architecture, and the optical transport module for the network node interface.

TL;DR: This article presents an experimental study on adopting and integrating the existing IP protocols and mechanisms into an optical network control plane that implements the key functions such as routing, signaling, protection/restoration, and quality of service.
Abstract: This article presents an experimental study on adopting and integrating the existing IP protocols and mechanisms into an optical network control plane. Although there has been much research effort on the conceptual and functional requirements for the control of optical networks, this article focuses on the design and implementation of an optical control plane. The proposed control plane implements the key functions such as routing, signaling, protection/restoration, and quality of service.
