The Cisco ONS 15454 ROADM cards (40-WXC-C, 40-WSS-C, and 40-WSS-CE) operate on the

ITU 100-GHz wavelength plan. Each card integrates automatic per-channel power control

capabilities, providing node-based and network-based automatic-power-level management. Per-

channel optical path selection is also done in a completely automated way through Wavelength

Path Provisioning (WPP) at the network level, featuring end-to-end point and click wavelength

provisioning and easy SONET/SDH-like wavelength management.

ROADM node architecture has been specifically defined and engineered to be able to provide:

●

High reliability: Complete independence between specific direction-facing units with the

possibility to house units in physically separated shelves.

●

Automatic optical power balancing: Per-channel automatic power control allows a “self-

healing” intelligent approach to DWDM.

●

Low insertion loss: Selected technology allows direct integration of different functionalities

in the same optical module, reducing to the bare minimum the number of optical

connections.

●

Fast switching time: 40-WSS-C and 40-WSS-CE units can be used to provide shared

optical protection directly in the optical domain with a protection time comparable with what

SONET/SDH is able to guarantee.

The optical cards incorporate faceplate-mounted LEDs to provide a quick visual check of the

operational status at the card. Printed on each of the faceplates is an icon, an orange circle, which

is mapped to shelf-slot icons indicating the shelf slot where the card can be physically installed.

The cards are supported by the integrated Cisco ONS 15454 Cisco Transport Controller craft

manager, which provides the user access for operations, administration, maintenance, and

provisioning (OAM&P) for the system. Using the embedded unit’s capabilities, Cisco Transport

Controller features also the possibility to provide a per-channel graphical representation of the

optical power levels associated with each individual path in the ROADM nodes (Figure 2).
