Ciena’s Common Photonic Layer is a selfoptimizing, agile DWDM transport platform designed for cost-effective metro, regional and long-haul networks. Its modular design provides an extremely small initial/final footprint and delivers significantly lower power consumption compared to other solutions. The platform offers operational simplicity by providing a high level of automation that facilitates network planning, engineering, configuration and deployment as well as accelerates the setup of end-to-end wavelengths.Â
Unlike other ROADM configurations that are directionally dependent where a TX/RX pair connected to a filter can only be sent out of the site in the direction of the line ports of the Wavelength Selective Switch (WSS) it is connected to, CPL allows for DirectionIndependent Access (DIA) where each direction can be remotely reconfigured. DIA allows the user to determine the optical direction of a channel out of a site via software and not a physical connection. The DIA configuration uses standard Wavelength Selective Switch (WSS), amplifier, and Optical Power Monitor (OPM) components to create the directionally independent access point. This simplifies the planning of ROADM sites/networks by allowing wavelengths to be remotely redirected to another direction for photonic restoration or for more optimal path routing as bandwidth requirements change.
Cost-optimized solution CPL offers an initial system with a significantly small footprint that scales modularly and provides a pay-as-you-go structure that can grow as revenue-generating opportunities or capacity exhaust drive expansion of the network. Deployments can scale anywhere between 5 to 2000km reach and beyond, and from 2 to 88 wavelengths and beyond. Each site is deployed with the footprint that matches its required capacity without limiting future scalability. CPL allows a seamless evolution to 100 Gb/s-based networking over existing 10 Gb/s lines on any fiber type (new/old, clean/dirty) without network reengineering or the deployment of dispersion compensating modules. Open photonic networking The Common Photonic Layer can be deployed in conjunction with Ciena’s optical networking products, including: 6500 Packet-Optical Platform, 5200 Advanced Services Platform, and Optical Metro 3500. Furthermore, the platform supports other vendor network elements for open photonic interworking.
CPL Network Management CPL is fully integrated into Ciena’s OneControl Unified Management System. Comprehensive screen layouts provide the network element health at a glance, pull-down menus for simple access to nodal management functions, and all relevant nodal management information. Faults are centralized in OneControl and inventory, provisioning and performance management can all be controlled via a common Graphical User Interface. OneControl provides a proven interface to manage CPL and all the subtending service layer optical equipment to offer a centralized, integrated solution at the Network Operations Center.
