The Cisco® Network Convergence System 2000 evolves the Cisco ROADM portfolio by introducing Cisco nLight ROADM technology. By supporting touchless reconfigurability through colorless, omnidirectional, and contentionless add/drop, networks built upon nLight ROADM can instantly respond to new bandwidth requests, route around network failures, and dynamically adjust their topology - all without manual intervention.

The Cisco NCS 2000 16-port Flex Spectrum ROADM Line Card (NCS2K-16-WXC-FS) is a double-slot unit that provides multidegree switching capabilities, not only at the individual wavelength level, but also with flexible spectrum allocations. You can use the 16-port Flex Spectrum ROADM Line Card in the core of the network to build ROADM nodes with 96 channels spaced at 50 GHz, Flex Spectrum channels, or a combination of the two. The same unit can provide colorless multiplexing and demultiplexing to ROADM nodes.

Features and Benefits

The 16-port Flex Spectrum ROADM Line Card creates an agile dense wavelength-division multiplexing (DWDM) layer, which provides 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, eliminating manual operator intervention to reduce operating expenses (OpEx) and accelerate provisioning and recovery.

This line card supports the following agile DWDM innovations and benefits:

   Colorless ROADM ports are not frequency-specific. This simplifies provisioning and allows dynamic restoration, because the frequency of an ingress channel can be retuned by software without requiring its fiber to be relocated.

   Contentionless add/drop allows an N-degree ROADM node to accommodate N wavelengths of the same frequency from a single add/drop device.

   Omnidirectional ROADM ports are not associated to a specific ROADM degree. Therefore a wavelength reroute does not require a physical fiber move, and it can be executed entirely by software.

   With Flex Spectrum, the amount of spectrum allocated to a wavelength can be flexibly provisioned to allow for multicarrier superchannels or single wavelengths exceeding today’s 50-GHz channel spacing (Figure 2).

Figure 2.      The Flex Spectrum Concept

Together, colorless, contentionless, omnidirectional, and Flex Spectrum (CCOFS) functionalities bring programmability to the optical layer, allowing direct and complete control by packet-layer devices and centralized network orchestrators.

Additional features of the 16-port Flex Spectrum ROADM Line Card include:

   High reliability: The line card node architecture allows complete independence among the direction-facing units, including the ability to house units in physically separated shelves.

   Flexibility: The 16-port Flex Spectrum ROADM Line Card can work either as a core building block of a ROADM node or as a colorless multiplexer/demultiplexer. Consequently, you can use 16-port Flex Spectrum ROADM Line Card ports to manage individual channels (multiplexer/demultiplexer operation) or to terminate optical multiplex sections, allowing network or ring interconnection without optical-electrical-optical (OEO) conversion.

Product Description

The 16-port Flex Spectrum ROADM Line Card is a 2-slot unit which has 36 input/output fibers among the following connectors:

   Two LC-duplex adapters for common (COM) and upgrade (UPG) ports

   Four MPO connectors for add, drop, and express (EXP) ports

The line card incorporates faceplate-mounted LEDs to provide a quick visual check of the operational status of the card. Each faceplate shows 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 Transport Controller craft manager, which gives the user access to system operations, administration, maintenance, and provisioning (OAM&P). Cisco Transport Controller can also provide a per-channel graphical representation of the optical power levels associated with each path in the ROADM node.

Figure 3 shows the internal layout of the 16-port Flex Spectrum ROADM Line Card, and Figure 4 shows the high-level nLight ROADM architecture, in this case of a 3-degree node.
