Gateway to the Automated Core
Scaling to a multi-terabit backbone network requires an architecture that
reduces not only capital cost, but also operational and opportunity cost.
Full-spectrum wavelength tunability in lasers and filters provides benefits
beyond simple inventory reduction. Combining tunable components and intelligent
optical signaling technologies allows service providers to minimize network
cost (capital and operational). Wavelength activation consists of remotely
tuning endpoint and, where necessary, mid-point resources to unused wavelengths.
Allowing remote wavelength turn up between any points across the core
network accelerates connection set-up and reconfiguration, and reduces
overall time to revenue.
Decoupling
Provisioning from Engineering
Tunable transceivers connected to tunable add/drop ports can be dynamically
configured as regeneration or wavelength conversion points along individual
connection paths. Combining this with the networked reach provided by
the DLS 1000 maximizes network efficiency by reducing pre-planning, engineering
and over-provisioned resources. The flexibility of provisioning without
wavelength pre-planning eliminates stranded capacity caused by building
to a forecast. Carriers can now build to order, reducing forecast errors
and increasing speed to revenue. While some amount of over-provisioning
is needed to ensure resources are available for rapid addition of capacity,
provisioned resources can be assigned dynamically to adapt to differences
between forecasts and orders.
Open Multi-Service
Interfaces
The on/off ramps to the agile photonic layer are accommodated with digitally
transparent transceivers. Using digital wrapper technology with enhanced
forward-error correction enables a mix of
sub-wavelength technology platforms across the same line system. This
includes SONET equipment, routers and electrical switches, in any combination.
Furthermore, the line system architecture is designed to accommodate various
bit-rates for increased efficiency as client
bit-rates evolve, extending the benefits of transparency and agility to
any client platform.
Enhancing
Visibility of the Photonic Network
Colorless DWDM allows the ability to perform
non-intrusive digital fault sectionalization and performance monitoring
along an end-to-end connection path. Since the AgileCore solution introduces
arbitrary length paths networked over transparent midpoints, the ability
to view detailed performance characteristics at these midpoints is critical.
Tunability enables
non-intrusive tap points to be inserted along an individual
path to give access to BER and Q metrics.
The AgileCore
Tunable Photonic Gateway helps service providers to automate the core,
providing rapid bandwidth delivery and unparalleled savings, scalability
and operational simplification.
