Cisco 21dBm Erbium Doped Raman Amplifier 26dB Span C-Band
Part Number: NCS2K-EDRA1-26C=
The Cisco® Network Convergence System (NCS) 2000 Series evolved the Cisco ROADM portfolio by introducing Cisco nLight reconfigurable add-drop multiplexer (ROADM) technology. The support of touchless reconfigurability through colorless, omnidirectional, and contentionless add/drop is based upon nLight ROADM and upon a new set of self-healing patch panel modules that dramatically reduce installation time and maintenance cost.
Product Introduction
The large numbers of ports on the Cisco NCS 2000 Flex Spectrum Single Module ROADM Line Cards are made possible by the twin-WSS route and select architecture featured by Cisco nLight ROADMs (Figure 1). 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 multidegree ROADM nodes, plus CCOFS add/drop, at large scale.
