TL;DR: In this paper, an approach to the realization of a broadband, flexible, multi-wavelength transport network employing an optical network layer is presented, and the transmission, switching, line, and management/supervisory subsystems and components are described.

TL;DR: In this article, a communication network system consisting of at least three nodes, which are interconnected by transmission links (110) carrying traffic to and from the nodes, is described, where each node can by itself divert traffic from the working ring (112) to the protection ring (114) and/or by itself divergences from the protected ring to the working circle (112).

TL;DR: Good optical-quality SiON layers deposited upon a SiO(2) buffer layer placed upon silicon wafers have been obtained by using plasma-enhanced chemical vapor deposition from SiH(4), NH(3), and N( 2)O.

TL;DR: A circuit for the management of any arbitrary polarization state of light is demonstrated on an integrated silicon (Si) photonics platform and was used in a WDM link and successfully used to adapt four channels into a standard Si photonic integrated circuit.

TL;DR: A transport architecture able to serve as a backhaul and fronthaul to convey radio traffic on the same optical infrastructure and a flexible control paradigm to facilitate optimal interactions of transport and radio resources while preserving a welldemarcated mutual independence are presented.
