In recent years, OFDM has been the focus of extensive research efforts in optical
transmission and networking, initially as a means to overcome physical impairments in …

Spectrum elastic optical networks support flexible central frequency and spectrum
assignment for lightpaths. When provisioning a new connection in an elastic optical network …

Elastic optical network (EON) architectures have been recently proposed as a candidate
solution for provisioning of both huge bandwidth and flexible connections in next generation …

In this article, we address the problem of static routing and spectrum allocation (RSA) in an
elastic optical network (EON) with dedicated path protection (DPP) consideration. We …

This chapter reviews the basics of Dense Wavelength Division Multiplexing (DWDM) and
shows how this will be superseded by a more flexible use of the optical fibre spectrum …

This chapter discusses the changes in technology option or design to support the elastic
concept in an optical network. Next, it introduces in detail some practical aspects of the …

Worldwide operator deployment of high-speed 100G coherent optical networks is currently
underway. To ensure a competitive solution offering significant performance improvements …

In this paper, we examine how typical transmission systems can be made tunable in
datarate, up to 100 Gb/s, through modulation-format versatility. We investigate through …

Located at the meeting point between telecom operators and over-the-top service providers,
metro networks are particularly well suited for the introduction of radical acceleration of …
