Programmability and agility
Cisco single-module ROADM line cards create an agile DWDM layer, forming the foundation for converged transport architectures, delivering features, that allow programmability and agility in provisioning and recovery operations. Wavelength add/drop and routing are entirely software-driven, which eliminates manual operations, helps decrease operating expenses (OpEx), and reduces provisioning and recovery times.

Scale and flexibility
The large numbers of ports on the Cisco single-module ROADM line cards are made possible by the twin-WSS route and select architecture, featured by Cisco nLight ROADMs. Channels are isolated by both the ingress and egress WSS, improving performance. By routing, instead of broadcasting, express channels, insertion loss is reduced, preserving optical signal-to-noise ratio (OSNR). The Cisco nLight architecture therefore allows multi-degree ROADM nodes, plus CCOFS add/drop, at large scale.
Cisco single-module ROADM line cards combine twin wavelength selective switches (WSS) with pre- and booster amplifiers in a single-slot line card. The line card features a switchable gain pre-amplifier, allowing optimal operation across two different gain ranges.
