“…The significant differences between the business models of NREN operators (typically publicly financed, non-profit organizations) and commercial operators makes the deployment of this technology in commercial networks more challenging. Despite several successful deployments [4]- [6], commercial network operators demand more evidence of non-disruptive, secure and robust deployment and operation [7] before considering the AW as a viable service. The following are the main challenges hindering the straightforward deployment of AWs in operational networks as given by various network operators [2], [7], [8]:…”

Standard operational practice mandates deploying expensive transponders at the borders between transport network domains. While this provides service guarantees, it also brings high service cost and increased end-to-end delay for the traffic. Deploying open WDM interfaces, often referred to as Alien Wavelengths, is one solution to overcome these drawbacks. This article provides an overview of the development of the Alien Wavelength technology to date. CAPEX and OPEX savings examples are provided together with an extensive analysis of the application of the open WDM interfaces for supporting the future optical Internet and its demanding applications. Our analysis indicates up to 60% savings in deployment cost and up to 70% savings in power consumption for hight bit-rate services deployed via open WDM interfaces.

“…This necessitates the deployment of new system for monitoring and control, which can be jointly designed and implemented in cooperation with the vendors. First steps in this direction are already available [1] though the application scenario is for the client-provider interface [2], [3].…”

Abstract-This paper presents a successful test-bed implementation of a multi-vendor transport network interconnection via open WDM interfaces. The concept of applying Alien Wavelengths (AWs) for network expansion was successfully illustrated via deployment of multi-domain/multi-vendor end-to-end OTN services. We evaluate the impact of AW service establishment on both native and other alien services. Our experience confirms the technical feasibility of the concept in the context of transparent network-to-network interconnection at the optical layer. Furthermore, main operational challenges are discussed.

“…An alternative approach is using IP over WDM, where IP routers have colored WDM optical interfaces which are suitable for longdistance transmission. IP over WDM has been demonstrated for 10G and 40G [1][2][3], but as traffic volumes continue to increase in the core network, high-speed 100G IP over WDM becomes a very attractive solution for bandwidth scalability and network efficiency. 100G has been developed rapidly in recent years with coherent technology and advanced modulation formats.…”

“…Generally, network operators have existing WDM infrastructures. To leverage the integrated high-speed IP over WDM technology in the routers and introduce it into their network, the high-speed WDM signals from IP routers need to be transported over existing third-party-vendor WDM infrastructure as an alien wavelength [1]. Therefore, the emerging high-speed coherent DWDM optics in the core routers and alien wavelength transport are two fundamental technologies to enable IP over WDM for future core networks.…”

We report the first successful coherent 100G IP over WDM alien wavelength field trial over WDM infrastructures spanning a total distance of 769 km, demonstrating the feasibility and robust performance of a simplified 100G IP over WDM core network architecture. Key performance aspects have been investigated including copropagation of a 100G IP over WDM alien wavelength and native wavelengths generated from WDM transponders, polarization mode dispersion tolerance, and operation without in-line dispersion compensation modules. We also demonstrated the feasibility of a 100G IP over WDM alien wavelength over multiple WDM systems and optical router or regenerator bypass. In addition, we show evaluation results on the key performance management and monitoring functions with a coherent 100G IP over WDM optical interface in the core router.
