“…A validation of the physical layer performance of passive filterless networks was carried out in [6], while a control plane solution based on path computation element (PCE) was presented in [7]. The dynamic operation of filterless network supported by the proposed control plane was evaluated in [8], indicating similar trends in the resource usage overhead as in the static scenario [5].…”

“…A major concern regarding resource consumption in filterless optical networks is the existence of unfiltered channels (shown in gray color in Fig.1a and 1b), which propagate all the way from the source to terminal nodes within a filterless fiber tree due to the drop-and-continue feature of filterless nodes [7]. The unfiltered channels increase the spectrum consumption, as the spectral resources occupied by them cannot be reused for other connections.…”

Abstract-We introduce the new concept of an elastic filterless optical network and propose an efficient heuristic algorithm for solving the static routing and spectrum assignment problem. Our simulation results obtained for different network topologies under multi-period traffic show increasing bandwidth savings with the growth of traffic load compared to a fixed-grid scenario. We also show the benefits of periodical spectrum defragmentation.

Active photonic switching components, such as reconfigurable optical add/drop multiplexers (ROADMs), cannot be deployed at the branching units (BUs) in submarine networks, which limits the flexibility of the undersea networks. In this regard, the filterless optical network architecture based on passive broadcast-and-select nodes and coherent transceivers at the edge terminals can be considered as a promising solution. In this paper we propose and evaluate a filterless network architecture for a trunk and branch undersea network topology. The performance is compared with a conventional solution in terms of cost and wavelength consumption. And it is shown that the filterless architecture can bring significant cost savings for both the terminals and line equipment while offering the same agility as the conventional network architecture.Index Terms-Optical networks, undersea networks, submarine applications, filterless optical network, coherent optical communication, network architecture and design, active photonic switching, broadcast-and-select, trunk and branch, branching unit (BU), routing and wavelength assignment (RWA).
