This unit is the key unit for the ROADM solution operating in the C band. It can remotely and automatically
control assignment of a wavelength to a network node. Dynamic Gain Equalization (DGE) is an automatic
per-channel power control capability, allowing this unit to be deployed also in selected line amplification sites
in the network to improve overall system performance.

The Cisco ONS 15454 ROADM cards operate on the ITU 100-GHz wavelength plan. Each card integrates automatic per-channel optical power
control capabilities, providing automatic node- and network-based power level management. Per-channel optical path selection is also done
automatically through Wavelength Path Provisioning (WPP) at network level, featuring GUI-based wavelength provisioning and easy
SONET/SDH-like wavelength management.
The ROADM node architecture provides:
•
High reliability – Complete independence between west- and east-facing units allows units to be housed in two separate shelves.
•
Automatic optical power balancing – Per-channel automatic power control allows a unique “self healing” intelligent approach to DWDM.
•
Low insertion loss – Direct integration of different functionalities in the same optical module reduces optical connections to the bare
minimum.
•
Fast switching – Currently deployed units can provide shared optical protection directly in the optical domain with a protection time
comparable with what SONET/SDH guarantees.
The optical cards incorporate LEDs on the faceplate to provide a quick visual check of the card’s operational status. An icon on each faceplate
is mapped to shelf-slot icons indicating the shelf slot where the card can be installed. The cards are supported by the integrated Cisco Transport
Controller craft manager, which provides access for operations, administration, maintenance, and provisioning for the system. Utilizing the
embedded units capabilities, Cisco Transport Controller can also provide a per-channel graphical representation of the optical power levels
associated with each individual path in the ROADM nodes (Figure 2).
