Elastic Optical Network (EON) is expected as one of future networks in terms of spectrum flexibility. While Routing and Wavelength Assignment (RWA) problem is one of the key issues in traditional Wavelength Division Multiplexing (WDM) networks, Routing and Spectrum Assignment (RSA) problem has much impact on network performance in EONs. On the other hand, Data-Center (DC) traffic and/or mobile back-haul traffic keep on increasing. To deal with such forthcoming huge capacity of applications, Space Division Multiplexing (SDM) technologies, such as Multi-Core Fiber (MCF) and few-mode fiber, are intensively researched. From network perspective, this paper focuses on Routing, Spectrum and Core Assignment (RSCA) problem for future SDM-EON.Introducing multi-core fibers makes RSA problem more complex because fiber-core dimension is newly expanded. In addition, physical impairment caused by MCF must be taken into account. In this paper, first, the target RSCA problem is divided into the routing and SCA problems, and Kshortest path based pre-computation method is introduced as the routing solution. Next, according to whether MCF has intercore crosstalk or not, we propose SCA methods with crosstalk awareness and with prioritized area concept, respectively. Finally, the paper evaluates the effectiveness of the proposed algorithms compared with representative ones.

In order to expand the transmission capacity of optical backbone networks, many innovative technologies such as Elastic Optical Network (EON) and Space Division Multiplexing (SDM) have intensively researched. These advanced network technologies require new optical node structures which can fully utilize the additional channels of the next-generation networks. Architecture on Demand (AoD) concept enables to construct flexible and scalable optical node structure by dynamically reconfiguring interconnections of building modules according to switching requests. Because resource allocation methods have impact on switching requests, the number and the types of building modules required for AoD nodes are dependent on not only traffic patterns but also spectrum allocations. In this paper, we propose spectrum and core allocation method based on spectrum region which is related with corresponding building modules of AoD nodes in Multi-Core Fiber Elastic Optical Networks (MCF-EONs). The proposed spectrum regions make two advantages. The one is reducing spectrum fragmentation which is an challenging issue in EONs. The other is replacing building modules of AoD nodes with simple and low-cost ones. Finally, we evaluate the proposed spectrum and core allocation method through computer simulations. The simulation results demonstrate that reducing spectrum fragmentation improves blocking probabilities and replacing building modules reduces modular costs of AoD nodes.

“…Multicore fibre (MCF) transmission, a type of space division multiplexing (SDM) relying upon encompassing several spatial paths within a single cladding structure, represents a promising technology for accommodating the increasing data rates required for future applications 1 . Over the past few years, MCF-systems have been shown to be capable of exhibiting sufficiently low crosstalk to support transoceanic transmission distances 2,3 , have transmitted high-order modulation formats 4 and achieved high-data rates while promising to be cost-efficient 5 . Nevertheless, to truly demonstrate the potential of MCF-systems, it is important to investigate their performance on realistic transmission links with integrated components in order to illustrate the practical challenges and the possible economical advantages of SDM.…”

1109-Tbit/s SDM transmission over 6,370 km using a full C-band seven-core EDFA

Abstract: We confirm the feasibility of 100-Tbit/s-class trans-oceanic SDM transmission. Using seven-core fiber spans with seven-core full C-band EDFAs, 7 × 264-channel quasi-Nyquist-WDM 60-Gbit/s PDM-QPSK signals are transmitted over 6,370 km.
