ADVA Optical Networking revamps FSP 3000 for metro networks

ADVA Optical Networking this week announced new capabilities for its FSP 3000 platform to align the platform with emerging optical metro network requirements. The enhancements leverage three building blocks for cost-effective ROADM capabilities, packet switching, and time synchronization.

The building blocks include:

• FSP 3000 MicroConnect: The metro-optimized optical layer capability enables ROADM features at fixed OADM prices, says Michael Ritter, VP, technical, marketing and analyst relations. The architecture offers 2-degree capabilities using an architecture based on a wavelength blocker, which Ritter says offers a more economical, less complex approach than conventional architectures. MicroConnect offers flexible-grid capabilities to support transmission of superchannels and other formats that may require more spectral width than the ITU channel grid supplies. The resulting optical layer also can support wavelength tuning and dispersion management, Ritter adds.
• FSP 3000 OpenFabric: As the name implies, this capability offers an open Optical Transport Network (OTN) packet switching fabric. OpenFabric offers sub-wavelength grooming, with input coming from transponders/muxponders or directly from a service's origin. ADVA developed the architecture, which offers significant scalability, in collaboration with some of its customers, Ritter says.
• FSP 3000 TrueTime: This synchronization capability supports both network synchronization and mobile wireless synchronization requirements in a manner designed to minimize fixed and variable delay asymmetries. TrueTime supports an out-of-band optical timing channel approach for metro core requirements, based on the use of grandmaster, boundary, and slave clocks. For mobile network support, a proprietary in-band OTN synchronization transport scheme that leverages dynamic buffer level control and predefined fill levels via what ADVA calls "TrueTime Mapping."

The new capabilities are compatible with software-defined networking (SDN) environments, particularly those that leverage ADVA's FSP Network Hypervisor. Additional features target operational simplicity via automation of such functions as performance monitoring and fault management, power-leveling and span-equalization, and self-tuned dispersion compensation, alongside guided fiber installation and ROADM commissioning.

Ritter says that some of these new elements are available and currently in customer labs.
