The Cisco® Network Convergence System (NCS) 2000 1.2 Tbps DWDM line module enhances dense wavelength-division multiplexing (DWDM) transmission with the new 400G client interface and 400GE client protocol support. The DWDM line module provides 1.2 Tbps of Client and 1.2 Tbps of Trunk capacity occupying 2 slots in NCS 2000 chassis. The line module is capable of mapping Client traffic to 200/300/400 Gbps Trunk wavelengths of ITU-T fixed or super channels providing customers bandwidth of 600G to 1.2T.

Product overview

The evolution of traffic at the access with 4G/5G technologies and 400GE at the data center and the service provider networks have resulted in the need for higher speed of transmission at the optical domain using new modulation scheme formats and the existing super channel capabilities on the optical fiber.

NCS 2000 1.2T DWDM Line module

Figure 1.               

NCS 2000 1.2T DWDM Line module

The Cisco NCS 2000 1.2 Tbps DWDM line module provides the best mode of transmission of the 100G and 400GE client protocols from access, metro, and core networks. NCS 2000 1.2T licensed version of the line module seamlessly helps to maintain and improve customer agility in turning up bandwidth on-demand considering no additional truck roll on an existing DWDM system or new line system. The DWDM line module is tuned to support both metro and long haul deployments with the necessary modulation formats/ trunk capacity per wavelength. This improves ROI for service providers to offer multiple services such as long haul transmission and metro transmission from the same line module.

Four coherent modulation formats are supported to best suit network requirements:

200G-DP-QPSK, 200G-DP-16QAM*, 300G-DP-8QAM, 400G-DP-16QAM

     200 Gbps dual polarization-multiplexed Quadrature Phase Shift Keying (QPSK)

     200 Gbps dual polarization 16-state Quadrature Amplitude Modulation (16-QAM)

     300 Gbps dual polarization 8-state Quadrature Amplitude Modulation (8-QAM)

     400 Gbps dual polarization 16-state Quadrature Amplitude Modulation (16-QAM)

*Future Release

The Cisco NCS 2000 1.2 Tbps DWDM line module (Figure 1) simplifies the integration and transport 100/400 Gigabit Ethernet and Optical Transport Unit Level 4 (OTU-4) interfaces and services into enterprises and service provider optical networks to best-in-class DWDM transmission capabilities.

Cisco 400G CFP2-DCO digital optics

Cisco coherent transmission technology greatly enhances the reach and reliability of transport performance while providing the flexibility to select the optimal modulation scheme for a specific application. The primary benefits of Cisco coherent technology are:

     Strong optical signal-to-noise ratio performance

     Outstanding chromatic dispersion robustness, avoiding any additional cost related to optical chromatic dispersion compensation equipment

     Extended polarization mode dispersion robustness

     Very high spectral efficiency, allowing wavelengths to be transmitted across a large number of ROADMs with negligible penalty

The CFP2 digital optical pluggable solution is the combination of the transceiver module and the DSP photonics integrated on a CFP2 form factor. Cisco offers a 400G CFP2-DCO pluggable optics module that addresses a wide range of network optical interconnect applications, including service provider access aggregation, wireless 5G backhaul, metro and long haul networks, and as data center interconnects. With support for Ethernet/OTN clients, and line-side transmission of 200 Gbps QPSK modulation up to 400 Gbps 16QAM, the module offers enhanced flexibility in a pluggable coherent solution. The CFP2-DCO product family features an expansive list of interoperability modes as documented by OpenROADM MSA and the Optical Internetworking Forum (OIF).

Pluggable solutions such as 400G CFP2-DCO are designed to enable network operators to address increasing bandwidth demand through a pay-as-you-grow model that has the potential of reducing both capital and operational expenditures. The 400G CFP2-DCO module incorporates a 7-nm CMOS technology and a silicon Photonic Integrated Circuit (PIC) for an optimized co-packaged design.

The Cisco 400G CFP2-DCO leverages this critical aspect by supporting oFEC for Open ZR and Open ZR+ modes and the standard C-FEC in the 400ZR mode.

Features and benefits

The Cisco NCS 2000 1.2 Tbps DWDM line module provides compelling benefits in the areas of efficiency, performance, flexibility, and density improvements.

Efficiency

In a single, 2-slot-wide line card, the 1.2 Tbps DWDM supports 100GE, 400GE, and OTU4* client protocols, providing the ability to groom the services into 3 wavelengths capable of up to 400 Gbps each.

Performance improvement

The latest generation of Digital Signal Processors (DSPs) provide a dramatic boost to the optical performance of 200 Gbps QPSK, 200 Gbps 16-QAM*, 300 Gbps 8-QAM, and 400 Gbps 16-QAM, allowing to support multiple deployment scenarios where throughput plays a key role in achieving maximum transmission capacity on fiber.

Flexibility

The service type of both Client and Trunk optics are based on pluggable modules, allowing a true pay-as-you-grow investment profile, where card personality is defined and redefined at the pluggable level. Due to the port-by-port service-type flexibility, this also radically reduces the variety of line cards an operator is required to inventory. The Cisco NCS 2000 1.2 Tbps DWDM line module provides 3 ports of QSFP-DD and 5 ports of QSFP 28 form factor, where the 3 ports of QSFD-DD can be used with QSFP28 for 100G client services.

Density

The Cisco NCS 2000 1.2 Tbps DWDM line module is able to triple the slot density compared with the previous generation of transponder cards.

Software configurable FEC option

The Cisco NCS 2000 1.2 Tbps DWDM line module features the new C-FEC and O-FEC adoption, providing the best performance based on the requirements on the network.

Management

The Cisco NCS 2000 system provides comprehensive management capabilities to support Operations, Administration, Maintenance, and Provisioning (OAM&P) capabilities through the integrated Nodal craft interface with support from the Cisco Evolved Programmable Network Manager (EPN-M) network management system. The 1.2 Tbps DWDM line card features ZR+ framing as well as ITU-T G.709 functionality, providing per-wavelength performance management capabilities, especially for services transported transparently across networks. Without the digital wrapper functions, a carrier transporting a service transparently would be unable to identify network impairments that may degrade the transported signal and violate the SLA agreements. The digital wrapper’s Generic Communication Channel (GCC) provides a separate communications channel on a per-wavelength basis to be used when transparent signals are transported. GCC allows the Cisco NCS 2000 system to extend its advanced network auto discovery capabilities to DWDM-based services.

Performance monitoring

The Trunk ports on the Cisco NCS 2000 1.2 Tbps DWDM line card provide support for transparent signal performance monitoring. The digital wrapper channel is monitored according to G.709 Optical Transport Network (OTN) and G.8021 standards. Performance monitoring of optical parameters on the client and DWDM interfaces include Loss of Signal (LOS), laser bias current, transmit optical power, and receive optical power. Calculation and accumulation of the performance monitoring data are supported in 15-minute and 24-hour intervals as per G.7710.

Physical system parameters measured at the wavelength level, such as mean polarization mode dispersion, accumulated chromatic dispersion, or received optical signal-to-noise ratio, are also included in the set of performance monitoring parameters. These can greatly simplify troubleshooting operations and enhance the set of data that can be collected directly from the equipment.

The DWDM card incorporates faceplate-mounted LEDs to provide a quick visual check of the operational status of the card. An orange circle is printed on the faceplate, indicating the shelf slot in which you can install the card.

Network applications

1.2 Tbps muxponder application (metro, long haul)

The Cisco NCS 2000 1.2 Tbps DWDM line card with QSFP28 and QSFP-DD provides a very efficient two-slot solution to transport on 16-QAM 400 Gbps traffic by using both 100/400 Gbps optical client ports, directly managed by the QSFP28 (both LR4, SR4, CWDM-4, SM-SR, FR-S) and QSFP-DD (DR-4, FR-4, LR-8, AOCxM) pluggable interface.

Multi-haul transport

By leveraging the trunk capabilities to configure each trunk with 200/300/400G DWDM, customers can get the benefit to cater to different needs in the network where 200G on one trunk caters to the Metro transmission and 400G on another trunk supporting Metro or DC-DC connectivities depending on the distance.
