The Nortel Common Photonic Layer is a self-optimizing, 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 current technologies. 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.

• Modular architecture that scales incrementally: footprint and cost matches required capacity and reach - low initial first cost, low incremental cost
• Automatic continuous dynamic system optimization, without the need for user intervention
• Management on a per wavelength granularity with support for remote configurability - no stranded capacity anywhere
• eROADM (Enhanced Reconfigurable Optical Add/Drop Capability) for total network agility
• Significant CAPEX/OPEX savings through footprint, power efficiency and automation of complex tasks
• One platform across the end to end network, for common spares, documentation, training, operations
