Available Languages
Product Overview
The Cisco® ONS 15454 Multiservice Transport Platform (MSTP) supports a trunk card that delivers Dense Wavelength-Division Multiplexing (DWDM) transmission using a coherent polarization-multiplexed differential quadrature phase shift keying (CP-DQPSK) modulation scheme. The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card (Figure 1) simplifies the integration and transport of 100 Gigabit Ethernet and Optical Transport Unit Level 4 (OTU-4) interfaces and services into enterprises and service provider optical networks.
Challenge and Solution
The bandwidth carried on core and metropolitan DWDM networks is growing exponentially, while operators’ revenues are not keeping pace. The Cisco ONS 15454 100-Gbps solution can dramatically lower the cost to carry bandwidth, helping to maintain and improve customers’ profitability. Internet growth is still exponential, mainly due to demand for next-generation services such as quadruple play (data, voice, video, and mobility), video distribution, Internet Protocol Television (IPTV), and other high-bandwidth services.
With advanced modulation schemes, the ability to transmit 100-Gbps wavelengths on existing or new DWDM systems improves return on investment by increasing the overall capacity per fiber pair without impacting the unregenerated transmission distance supported by the system. Scaling from 10 Gbps to 40 Gbps and now 100 Gbps increases by a factor of 10 the bandwidth that can be transported over existing fiber networks.
The new CP-DQPSK modulation supports 9.6 Tbps capacity transmission over Ultra-Long-Haul (ULH) networks of up to 3000 km of unregenerated optical spans.
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card is designed to provide the following benefits:
● Transport of 100-Gbps wavelengths over fully uncompensated networks, up to 3000 km of unregenerated optical spans
● Transport at 100 Gbps over very low-quality fiber with very high Polarization Mode Dispersion (PMD)
● Support for up to ninety-six 100-Gbps wavelengths (50-GHz channel spacing) with very high tolerance to filtering penalties
● Improved overall system density for 100 Gbps per slot, five times greater than the density achieved with 40‑Gbps units
● Support for different configurations (transponder, muxponder, or regenerator) through software provisioning only
Product Features and Benefits
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card is a plug-in module to the Cisco ONS 15454 MSTP, providing a cost-effective architecture for delivering 100-Gbps services. The card also features a pluggable client interface that can be used to provide transponder capabilities, mapping the client signal to a single DWDM line interface.
The client port supports a standard Channel Express (CXP) format pluggable compliant with IEEE 100GBASE-SR10 LAN PHY or OTU-4 equivalent interface.
The trunk card features a software-configurable baud rate between 27.952 Gbaud and 31.241 Gbaud, depending on Forward Error Correction (FEC) selection as well as a G.709v3 OTU-4 digital wrapper, long-reach and long-haul, ITU-compliant, 50-GHz spaced optical interface using LC connectors. The DWDM output line interface is tunable to 96 wavelengths across the full optical C band, dramatically reducing inventories for spares. When operated within the outlined specifications, the trunk card can operate with a post-FEC bit error rate (BER) of better than 10E-15.
The trunk card provides many carrier-class features and advanced capabilities necessary to deliver 100-Gbps services, including protocol transparency, wavelength tunability, flexible protection mechanisms, flow-through timing, and management and performance monitoring capabilities (Figure 2).
Enhanced Forward Error Correction Capability
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card can support FEC mechanisms on trunk and client interfaces.
The trunk port supports three software-configurable FEC coding options, which cannot be disabled.
● Generic FEC (GFEC): Standard G.975 Reed-Solomon algorithm with 7 percent overhead (OH).
● Ultra FEC (UFEC): Standard G.975.1 (Subclause I.7) with 20 percent overhead. This FEC scheme uses two orthogonally concatenated BCH Enhanced FEC (EFEC) codes. The constructed code is decoded iteratively to rebuild the original frame.
● High-Gain FEC (HG-FEC): High-Gain FEC with 7 percent overhead, providing better performance than standard G.975.1 seven percent overhead FEC. Because of the reduced overhead and lower bit rate, HG-FEC is suitable for applications where 100-Gbps wavelengths are passing through a large number of reconfigurable optical add-drop multiplexer (ROADM) nodes with limited pass-band performance.
The client port supports the standard G.975 Reed-Solomon FEC algorithm, which can be enabled or disabled through software configuration.
Advanced Modulation Scheme
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card features an advanced modulation scheme to provide optical performance significantly better than industry-standard 10-Gbps equivalent interfaces.
Cisco selected a CP-DQPSK modulation format to optimize 100-Gbps transmission in terms of Optical Signal-to-Noise Ratio (OSNR), Chromatic Dispersion (CD), and Polarization Mode Dispersion (PMD) robustness.
The CP-DQPSK modulation scheme consists of multiplexing two DQPSK signals using two different orthogonal light polarizations, as shown in Figures 3 and 4.
The core of the 100-Gbps CP-DQPSK modulation scheme is the optical receiver, based on coherent optical detection, where a Digital Signal Processor (DSP) calculates the inverse of the optical system matrix, allowing the receiver to recover the original transmitted signals (Figure 5).
The primary benefits of CP-DQPSK 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 (three times better than 10-Gbps units)
● Very high spectral efficiency, allowing 100-Gbps wavelengths to be transmitted across a large number of ROADMs with negligible penalty
Trunk Card Versions
Two versions of the Cisco ONS 15454 100 Gbps Coherent DWDM Trunk card are offered to support different application requirements:
● An extended-performance version offering full performance targeting Ultra Long-Haul applications where the network is optimized for CP-DQPSK transmission (no 10-Gbps channels or dispersion compensation units [DCUs])
● A metro edge performance version with differential mode only (CP-DQPSK), cost-optimized for metropolitan application and 10-Gbps installed networks
Protocol Transparency
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card can transparently deliver 100-Gbps point-to-point services cost-effectively for the Cisco ONS 15454 MSTP platform. Table 1 shows transponder client configurations and mapping.

Wavelength Tunability
The trunk card supports software-provisionable tunability across the full C band, covering 96 channels on the 50-GHz grid. Tunability provides flexibility and reconfigurability of services transported on ROADM-based networks, and also allows ordering and inventory of a single part for deployment and sparing.
Flexible Protection Mechanism Support
The trunk card supports multiple protection mechanisms commonly used in optical transport networks. Table 2 outlines the available protection options and the associated service-level agreements (SLAs) that can be provided.
Table 2. Protection Formats
| Protection Type |
Capabilities |
| Unprotected |
No client terminal interface, transponder card, or DWDM line protection. The client signal is transported over a single unprotected transponder card or optical path. |
| 1+1 protection |
Provides protection for the client terminal interface, transponder card, and DWDM line through client Automatic Protection Switching (APS) or Linear Multiplex Section Protection (LMSP) signaling transported transparently over the transponder card or optical path. Protection is provided through client line or path protection through transparent signal transport through a transponder circuit. |
| OCH-trail protection |
Provides protection for DWDM signal through external optical switch units: Protection Switch Module (PSM). |
Flow-Through Timing
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card allows timing to flow through from client to line optical interface. The received timing from the client interface is used to time the line transmitter interface. This flow-through timing allows multiple trunk cards to be placed in the same shelf but be independently timed, independent of the network element timing.
Management
The Cisco ONS 15454 MSTP system provides comprehensive management capabilities to support Operations, Administration, Maintenance, and Provisioning (OAM&P) capabilities through the integrated Cisco Transport Controller craft interface with support from the Cisco Prime™ optical element management system. The trunk card features provisionable digital wrapper (G.709) functionality, providing per-wavelength performance management capabilities, especially for services transported transparently across the network. 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 by the platform when transparent signals are transported. GCC allows the Cisco ONS 15454 MSTP system to extend its advanced network autodiscovery capabilities to DWDM-based services. The integrated Cisco Transport Controller craft manager and Cisco Prime provide the user with OAM&P functionalities for the system.
Far-End-Laser-Off Behavior
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card can provision the far-end-laser-off behavior when SONET/SDH payloads are present. Customers can use Cisco Transport Controller to configure how the remote client interface will behave following a fault condition. It is possible to configure the remote client to Squelch or to send an Alarm Indication Signal (AIS). For 100-Gigabit Ethernet signals, the default behavior is Squelching.
Performance Monitoring
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card provides support for both transparent and nontransparent signal transport 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 line interface 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. A detailed list of performance monitors is given in Table 8.
The trunk 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.
A specific configuration of the client will support IP over DWDM (IPoDWDM) proactive Fast Reroute (FRR) messaging over the CXP client in case of 100 Gigabit Ethernet connectivity.
Regeneration Application
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card supports OTU-4 regeneration capabilities. Two cards can be configured to work in back-to-back mode connecting through the backplane in the same shelf, and perform the OTN Optical-Electrical-Optical (OEO) regeneration of the frame as depicted in Figure 6.
100 Gigabit Ethernet or OTU-4 clients are supported. Regeneration capability uses the OTU-4 backplane interconnection supported by the Cisco ONS 15454 MSTP M6 or M2 chassis; OTU-4 overhead is terminated, allowing ODU-4 traffic to transparently pass through. GCC0 is properly terminated, while GCC1 and GCC2 are properly passed through (Figure 7).
No CXP client is required, as communication between the two cards acting as a regeneration group is supported through the chassis backplane.
A dedicated IPoDWDM configuration can be enabled in the regeneration configuration to support proactive FRR messaging between IPoDWDM router interfaces.
In case of failure on one side, ODUk-AIS is generated and propagated on the other side while an OTUk-BDI is sent back on the same side as defined by the ITU G.709 standard.

Application Description
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card provides cost-effective 100-Gbps transport services using the Cisco ONS 15454 MSTP platform.
Two main applications promote the 100-Gbps deployments.
● 100-Gbps router interconnection for business services and research networks: Cisco research indicates that the total volume of worldwide IP traffic is doubling every two years, requiring an increase in transfer rate from 10 Gbps to 100 Gbps. The transponder solution aims to provide DWDM interconnection between 100-Gbps router interfaces across DWDM metro, regional, or ULH networks. The advanced CP-DQPSK modulation scheme is designed to cope with long-distance applications, allowing the extension of unregenerated 100-Gbps services across fiber spans up to 3000 km.
● OTU-4 links in carrier backbone networks: OTN technology is crucial to backbone carrier networks. OTN is normally the preferred method used for inter-carrier or inter-domain capacity exchange at 2.5-Gbps (OTU-1), 10-Gbps (OTU-2), 40-Gbps (OTU-3) and 100-Gbps (OTU-4) data rates. The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card supports a fully standard OTU-4 client interface, which can be connected to any G.709-based OTN cross-connect, 100-Gbps router interface, or other 100-Gbps transponder interfaces.
Licensing Approach
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card includes the ability to cost-effectively transport 10-Gbps services through a pay-as-you-grow licensing model for the 10-Port 10-Gbps muxponder configuration. A licensed version of the Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card works in conjunction with a licensed version of the Cisco ONS 15454 10-Port 10 Gbps Line Card, offering a cost-effective solution for aggregation and transport of 10-Gbps services. These two cards can only work in this configuration. Additional 10-Gbps services will be provided by mounting a 10-Gbps license through software key distribution. Up to nine additional 10-Gbps licenses can be added to the Cisco ONS 15454 10-Port 10 Gbps Line Card (only one is provided in the initial configuration).
To simplify spares management, it is also possible to upgrade the licensed version of the trunk card to full functionality.
