The Dynamic Optical Layer consists of ROADM-on-a-Blade (ROB) modules for flexible, point-and-click wavelength routing, and DWDM Line Amplifier (DLA) modules for reach extension in an extremely compact form factor. The common control system, integrated on ROB and DLA modules, enables plug-and-play operation to simplify the planning, deployment, service provisioning, ongoing optimization, and power management of the network.
