In today's era of rapidly growing communication needs and data traffic, optical networks are a key building block of modern telecommunication networks. Cisco Systems is one of the leading providers of optical networking solutions. Their optical solutions include a wide range of Dense Wavelength Division Multiplexing (DWDM) technologies that are implemented in the Network Convergence System (NCS) 1000 to 4000 Series family of optical switches. These technologies enable the efficient transmission of information over long distances and improve connectivity between data centers, enterprise networks, ISPs and telecommunications carriers.
The latest innovations are the implementation of RON (Routed Optical Networking) Architecture. RON is a new architecture with a focus on increasing operational efficiency and simplifying service provider network solutions. RON integrates IP and private line services into a single layer and consolidates all switching operations at Layer 3. Routers are interconnected using coherent 400G ZR/ZR+ optical DCO modules. The consolidation of services into a single IP-based layer makes management more flexible. The solution makes significant use of telemetry and programmability to ensure maximum operational efficiency.
