Semi-filterless optical networks (semi-FONs), a novel passive wide area network (WAN)
solution, have attracted considerable attention. This paper investigates the dynamic routing …

We demonstrate wavelength conversion based on four-wave mixing in a semiconductor
optical amplifier of signals with quadrature amplitude modulation (QAM). We first …

Today's optical networks must meet the unprecedented capacity requirements of 5G
communications and provide such capacity under strict cost constraints. Filterless Optical …

Enabling Dedicated Path Protection (DPP) in Filter-less Optical Networks (FONs) poses
specific design challenges, as FONs require dividing the network topology in non …

In this paper, the filterless optical network concept is presented and explored through a
number of filterless solution examples. In the first part, the filterless network concept is …

Filterless Optical Networks (FONs) in which optical nodes are formed by only passive
splitters and combiners, are widely-adopted technical solution for transport networks …

In this article, we present the concept of the filterless optical network from a control plane
perspective, defining the network and showing to what extent a control plane could be …

In Filterless Optical Networks (FONs), passive splitters and combiners replace the more
complex and more expensive Reconfigurable Optical Add-Drop Multiplexers (ROADMs) …
