Using the Cisco NCS 2000 Series, you can deploy a simple, yet intelligent dense wavelength-division multiplexing (DWDM) network that scales with operational ease. The Cisco NCS 2000 Series delivers agility with a touchless, flex-spectrum reconfigurable optical add/drop multiplexer (ROADM), and massive scale with 100- and 200-Gbps transponding and muxponding. Figure 1 shows three models of the Cisco NCS 2000 Series.
nLight ROADM Innovation
Over a decade ago, the Cisco ONS 15454 MSTP brought ROADM technology mainstream, allowing service providers, governments, and enterprises to deploy a simple, yet intelligent DWDM network that could scale with operational ease. The Cisco NCS 2000 Series evolves the Cisco ROADM portfolio by introducing Cisco nLight™ ROADM technology. By supporting touchless re-configurability through colorless, omnidirectional, and contentionless add/drop, networks built using Cisco nLight ROADM technology can instantly respond to new bandwidth requests, route around network failures, and dynamically adjust their topology. And they can do it all without manual intervention. Highly meshed networks will benefit from support of up to 40 degrees of connectivity, while flex-spectrum capability optimizes spectrum utilization while protecting your investment in the photonic layer. Innovative single-module ROADMs integrate wavelength switching and amplification into a single-slot line card, simplifying node configurations and minimizing footprint.
100G and Beyond
Continuing Cisco’s innovation in optical technology, nLight Silicon enables multirate DWDM line cards for the NCS 2000, which offer variable bit rates based on a software-configurable modulation scheme. The network operator can flexibly optimize the spectral efficiency and reach characteristics of each wavelength, improving network capacity and efficiency. State-of-the-art coherent digital-signal-processing (DSP) technology with soft-decision forward error correction (SD-FEC) enables 100-Gbps wavelengths to achieve unregenerated distances of up to 4500 km. Metro/regional networks can take advantage of 200-Gbps wavelengths, while ultra-long-haul networks can use 50-Gbps modulation to achieve transoceanic unregenerated distances.
Multilayer Network Intelligence
The Cisco NCS 2000 Series Wavelength Switched Optical Network (WSON) control-plane architecture enhances GMPLS capabilities with awareness of wavelength properties and optical impairments, offering dynamic service provisioning and restoration over a touchless DWDM network. Using a Cisco nLight Control Plane, the Cisco NCS 2000 Series intelligently interacts with packet layer devices, automating service provisioning, eliminating human error, and allowing advanced failure recovery.
Smooth Platform Integration and Interoperability
The Cisco NCS 2000 Series transparently integrates with the Cisco NCS 4000 at the network element, network management, and control plane levels, creating a unified packet optical transport system encompassing DWDM plus OTN and packet switching. The Cisco NCS 2000 Series also offers full support for Cisco ONS 15454 MSTP line cards, plus network level interoperability and unified management, helping ensure a smooth migration for customers with existing ONS 15454 MSTP networks.
Chassis Features and Options
The Cisco NCS 2000 Series offers three chassis variants to meet varying scale and space requirements. The Cisco NCS 2015 has 15 slots for service cards and is 14 rack units (14RU) high, allowing three chassis to fit into one standard rack (Figure 2). The Cisco NCS 2006 chassis is 6RU and has 6 slots for service cards (Figure 3). The NCS 2002 is 2RU and has 2 slots for service cards (Figure 4). Multishelf management allows multiple (up to 50) NCS 2015 and NCS 2006 shelves to be managed as a single network element, with a single target identifier (TID) and IP address, facilitating the construction of nodes with a very large number of ROADM degrees and/or service cards.
Cisco NCS 2000 Series chassis contain built-in memory to back up the software package, IP address, and circuit database. This built-in backup memory improves mean time to repair (MTTR) and increases operational simplicity. Also available on Cisco NCS 2000 Series chassis is the ability to connect passive devices via USB for performance and inventory management. Cisco NCS 2000 Series passive devices include memory containing device information, and photodiodes for measurement of power levels and connectivity verification. Table 1 compares the features.

Cisco NCS 2015
The Cisco NCS 2015 chassis is ideal for high degree-count ROADM nodes or network hubs with large quantities of transponder or muxponder line cards. Two versions of the chassis support AC or DC power applications. Four slots accommodate up to four power modules (up to 3 + 1 redundant configuration for DC power and up to 2+2 redundant configuration for AC power), and are common to both the NCS 2000 and NCS 4000 Series. Power-cabling connectors are decoupled from the power modules themselves, allowing easy replacement of a module with no impact on cabling.
Airflow through the chassis is front-to-back, facilitating hot-aisle/cold-aisle installations. A replaceable fan tray containing eight fans divided among two separate circuits sits above the line cards, and also houses timing and alarm input and output connectors. Air is drawn in through a 2-inch input plenum at the bottom of the chassis, and expelled at the top-rear.
Cisco NCS 2006
At 6RU with 6 service slots, the Cisco NCS 2006 chassis is versatile. Metro/edge locations can minimize footprint while still accommodating multiple ROADM degrees and/or service line cards, and large core nodes can scale as large as necessary by using multishelf configurations.
You can configure the Cisco NCS 2006 chassis with DC or AC power inputs. The DC power module has connectors for both ANSI- and ETSI-style battery connections, making it universal. The AC power modules have a single input and are universal in that they accept a power input ranging from 110 to 240 VAC, 50 to 60 Hz.
The Cisco NCS 2006 can be mounted into 19-, 21-, or 23-inch racks or cabinets. Brackets come with the shelf assembly and can also be ordered as spares. You can use optional air deflectors in 21- and 23-inch installations. Airflow is side-to-side, but you can add deflectors for front-to-back and front-to-front airflow. In the 21-inch configuration airflow could also be front-to-top. Additionally, an air plenum is available that you can be used for front to back airflow in 19-inch rack configurations.
Cisco NCS 2002
The Cisco NCS 2002 is ideally suited to line amplifier configurations, a 2-degree ROADM node, or anywhere that only 2 slots are required for transponding or muxponding services. It features 1 slot for the control card and 2 slots for service cards. You can configure the NCS 2002 with a single DC or AC power module. The DC power module has inputs for redundant A and B feeds. The integrated AC power module has a single input and is universal in that it accepts a power input ranging from 110 to 240 VAC, 50 to 60 Hz.
Although a single processor card controls the node, the NCS 2002 contains a built-in memory module to back up the software package, IP address, and circuit database. This backup capability improves MTTR and increases operational simplicity. Integrated RJ-45 and USB ports provide management connectivity and passive device connectivity, respectively. Timing inputs and outputs are also present.
Been working with PICS Telecom for years. Wonderful company and Bill McAuliffe is a great rep to work with!
I think Bill McAuliffe is the best. Always helpful and has gotten me out of a lot of jams.
I work with Bill McAuliffe and a lot of times we are buying switches but often we have off the wall or weird equipment that we have to find and Bill often times goes above and beyond. He may not always be able to get us the best price, but we definitely come back for the Service and effort.
I have worked with PICS Telecom for years and it has been a wonderful experience. Every one is very supportive and provides excellent customer service. Bill McAuliffe always goes above and beyond to address our needs and locate (or in some cases, build) difficult-to-find equipment.
Worked with Bill McAuliffe finding some much needed, hard to find parts. He hooked me up and was a pleasure to deal with. Will definitely buy from again!
Found Pics Telecom during a online search for secondary market equipment. Had a conversation with Bill and he helped me find the equipment I was looking for and gave me a great price! I have completed 2 other transactions with him since then. This is a wonderful company to work with, Thanks Bill for all of your help, you have been awesome to work with and I look forward to working with you on future equipment needs.
We have worked with Bill several times on several projects and Bill has never let us down. He is always quick to respond to our questions and can acquire specific gear we are looking for within a very short period of time.
Bill is always very helpful on getting the equipment we need. He is fast in response time and always competitive pricing. If there is any issues with the equipment after receiving it he has replaced it with no questions. In short a good person / company to deal with.
I appreciate the quick response and shipping. I try to check with you any chance I get when I need to purchase Ciena gear. You have great pricing and I have not received a defective unit yet so I know that I will get a quality part when I purchase thru you.
Thank you and it’s been a pleasure working with you and your team! I look forward to doing more business with you in the future!
I have been pretty fortunate lately in regards to equipment failures and replacements, but PICS has always been (thanks to the quality of service I’ve received from you) at the top of my list when I do have a need.
