“…To ensure higher utilization and financial viability, multi-flow transponders or SBVTs, have been proposed. An SBVT is capable of generating multiple optical flows that can be routed to different destinations, thus sharing the capacity of a single transponder between multiple source-destination pairs [14], [15], [24]. …”

Abstract-Elastic optical networks (EON) have been proposed to meet the network capacity and dynamicity challenges. Hardware and software resource optimization and re-configurability are key enablers for EONs. Recently, innovative multi-carrier transmission techniques have been extensively investigated to realize high capacity (Tb/s) flexible transceivers. In addition to standard telecommunication lasers, optical carrier generators based on optical frequency combs (OFC) have also been considered with expectations of reduced cost and inventory, improved spectral efficiency and flexibility. A wide range of OFC generation techniques have been proposed in the literature over the past few years. It is imperative to summarize the state of the art, compare and assess these diverse techniques from a practical perspective. In this survey, we identify salient features of optical multicarrier generators, review and compare these techniques both from a physical and network layer perspective. OFC demultiplexing/filtering techniques have also been reviewed. In addition to transmission performance, the impact of such sources on the network performance and real-world deployment strategies with reference to cost, power consumption, and level of flexibility have also been discussed. Field trials, integrated solutions, flexibility demonstrations are also reported. Finally, open issues and possible future directions that can lead to real network deployment are highlighted.

“…Different combination of multiple optical paths with variable/equal bandwidth are formed and routed or sliced to the same or different destinations. Various architectures for SBVT designs have been proposed and demonstrated in [38][39][40]. Also a cost analysis of SBVT in a network scenario has been presented in [41], showing that SBVT reduce the cost of transponders by 30%.…”

Flexible optical networks will provide the required service diversity to manage unpredictable traffic patterns and growth. However, a key challenge is to quantify flexibility in order to indicate the associated performance of individual components and subsystems required to support networks and correlate it with other figures of merit. Measurable key performance indicators will aid the process towards the design and deployment of cost effective and efficient optical networks. Moreover, the design and placement of network elements within a network influences the resultant network-wide flexibility and performance. In this paper, we highlight critical design parameters for key optical components, optical transmission and switching subsystems using flexibility as an additional figure of merit. We derive models to measure the flexibility of key optical components, optical transmission and switching subsystems based on entropy maximization. Using these models, we evaluate flexibility and design trade-offs of the presented enabling technologies with other key performance indicators such as spectral efficiency, lightpath reach, total capacity, normalized cost, connectivity and others. This study provides an advanced and more informed set of design rules that quantify and visualize the different degrees of flexibility of enabling technologies and associated performance based on required specification and/or functionality.

“…The adaptation of the optical launch power [12], [13] and mitigation of nonlinear interference using, for example digital back propagation (DBP) [14], [15], can improve the properties of the light path. The use of flexible grids with adaptive signal bandwidth [16], superchannels and sliceable transceivers [17] allows the light path bandwidth to be better matched to the clients data requirements. With all of these the size of the adaptation control steps are important and it has been shown that finer steps improves network throughput [18], [19].…”

Abstract-In this paper we link the throughput gains, due to transceiver adaptation, in a point-to-point transmission link to the expected gains in a mesh network. We calculate the maximum network throughput for a given topology as we vary the length scale. We show that the expected gain in network throughput due to transceiver adaptation is equivalent to the gain in a point-to-point link with a length equal to the mean length of the optical paths across the minimum network cut. We also consider upper and lower bounds on the variation of the gain in network throughput due to transceiver adaptation where integer constrained channel bandwidth assignment and quantized adaptations are considered. This bounds the variability of results that can be expected and indicates why some networks can give apparently optimistic or pessimistic results. We confirm the results of previous authors that show finer quantization steps in the adaptive control lead to an increase in throughput since the mean loss of throughput per transceiver is reduced. Finally we consider the likely network advantage of digital nonlinear mitigation and show that a significant trade off occurs between the increase in SNR for larger mitigation bandwidths and the loss of throughput when routing fewer large bandwidth superchannels.
