    The Cisco® ONS 15454 Multiservice Transport Platform (MSTP) supports a 4-Port 10-Gbps Full-Band Tunable DQPSK Muxponder Card, which expands the platform’s 10-Gbps interface density. The card facilitates the delivery of transparent 10-Gbps-based services for enterprises or service provider optical networks (Figure 1).

    Cisco ONS 15454 MSTP Release 9.2 extends the overall data bandwidth that can be transported by the system by a factor of four, supporting transmission of up to 320 channels at 10 Gbps over 80 wavelengths at 40 Gbps.



    The traffic carried on core and metro DWDM networks is growing exponentially, while operators’ revenues are failing to keep pace. The Cisco ONS 15454 40-Gbps solution can dramatically lower the cost to carry this traffic, helping operators to maintain and even increase profitability.

    Internet usage is still skyrocketing, primarily due to demand for next-generation services such as quadruple-play, video distribution, IPTV, and an array of high-bandwidth services.

    This massive traffic growth is creating bottlenecks in DWDM networks that require a technology leap to support the surge in bandwidth. Scaling from 10 Gbps to 40 Gbps solves this problem by quadrupling the amount of traffic that can be transported over existing fiber.

    The Cisco ONS 15454 MSTP 4-Port 10-Gbps Full-Band Tunable DQPSK Muxponder Card allows you to upgrade your existing DWDM system without any additional equipment (such as a DCU). The card meets the following three critical requirements:

     40-Gbps signals will work on already deployed 10-Gbps systems.

    - 40-Gbps technology will support comparable chromatic dispersion (CD) robustness, polarization-mode dispersion (PMD) robustness, and optical signal-to-noise ratio (OSNR) with existing 10-Gbps transponders.

     40-Gbps technology will work on 50-GHz system as well as current 10-Gbps wavelengths (with comparable filtering penalty).

     40-Gbps units will fit mechanically and thermally with existing installed shelf with no impact on existing units, allowing full compatibility and no restriction on where the units can be placed.

    Product Overview

    The Cisco 4-Port 10-Gbps Full-Band Tunable DQPSK Muxponder Card can transport four OC-192/STM-64/10GE LAN/10GE WAN/8G FC/10G FC/OTU2 payloads over a G.709 OTU‑3-based, 50-GHz spaced, 50-GHz stabilized, ITU-compliant wavelength with selectable Enhanced Forward Error Correction (E-FEC). The muxponder card is a plug-in module to the Cisco ONS 15454 MSTP, enabling a high-density, cost-effective solution for 10-Gbps services transport over a platform capable of low-rate services down to 1.5 Mbps. The muxponder card architecture contains four client interfaces that are mapped to a single line interface, without accessing the Cisco ONS 15454 shelf cross-connect fabric.

    Each client interface provides a multiservice interface (OC-192/STM-64/10GE LAN/10GE WAN/8G FC /10G FC/OTU2) through a 10G Small Form-Factor Pluggable (XFP) opticsmodule with LC connectors, providing the flexibility to support several optical reaches with support for qualified XFP modules. The muxponder card supports any mixtureofXFP reach types and also supports in-service insertion or removal without affecting other active ports, allowing superior networkingflexibility and reduced pre-planning activities.

    Various types can be used depending on reach and application:

    The DWDM line interface provides a configurable 43.018-Gbps/44.570-Gbps G.709 OTU-3 digital wrapper, long-reach/long-haul, ITU-compliant, 50-GHz spaced optical interface using LC connectors supporting G.709 OTU-3 digital wrapper interfaces. The DWDM output line interface is tunable across full optical C band, dramatically reducing inventories for spares. When operated within the outlined specifications, each card will transport each of the 10-Gbps signals with a maximum bit error rate (BER) of 10E-15.

    The muxponder card incorporates the four clients and one DWDM line interface on the same card. The muxponder card is deployable in any of the12 multiservice interface card slots of the Cisco ONS 15454 platform, in systems with or without cross-connect cards. The addition of a cross-connect card enables the platform to support hybrid applications, containing transparent 10-Gbps services as well as aggregation of the other services supported by the Cisco ONS 15454 platform. The only other common card required for operation is the timing, communications, and control card (TCC).

    The muxponder card provides many carrier-class features and capabilities necessary to deliver 10-Gbps services, including selectable protocol transparency, wavelength tunability, flexible protection mechanisms, flexible timing options, and management capabilities.

    Enhanced FEC Capability

    The card supports the Forward Error Correction (FEC) mechanism on trunk and client interfaces.

    The trunk port supports FEC and E-FEC and such mechanisms cannot be disabled. The output bitrate will not depend on the selected algorithm but the error coding performance can be provisioned:

     FEC: standard G.975 Reed-Salomon algorithm

     E-FEC: standard G.975.1 (Subclause I.7) two orthogonally concatenated BCH super FEC codes. This FEC scheme contains three parameterizations of the same scheme of two orthogonally interleaved block codes (BCH). The constructed code is decoded iteratively, to achieve the expected performance. E-FEC provides 2 dB of additional reach respective to standard FEC. This E-FEC algorithm can be enabled in three of the four client ports (Port 1 cannot support E-FEC).

    Client ports, pending the support of FEC rate on the pluggable, can support the FEC mechanism which can be disabled.

     FEC: standard G.975 Reed-Salomon algorithm on all four client ports

     E-FEC: standard G.975.1 (Subclause I.7) two orthogonally concatenated BCH super FEC codes.

    Advanced Modulation Scheme

    The Cisco 4-Port 10-Gbps Full-Band Tunable DQPSK Muxponder Card features an advanced modulation scheme to achieve performance comparable to industry-standard 10-Gbps equivalent units.

    Cisco selected an RZ-DQPSK modulation format (Return-to-Zero Differential Quadrature Phase Shift Keying) in order to optimize 40-Gbps transmission in terms of OSNR, CD robustness, and PMD robustness.

    RZ-DQPSK is a four-level Phase Modulation scheme where four “signal points” are used. Each “phase” or “signal point” carries two bits. See Figure 3.

    Figure 3. DQPSK Phase Domain Scheme


    The main advantages of RZ-DQPSK are:

     Good OSNR performance, similar to 10-Gbps units

     Equivalent CD robustness to 10-Gbps units

     Good PMD robustness compatible with existing 10-Gbps units

     Very good spectral density that will allow crossing a long cascade of ROADM with negligible penalty

    Protocol Transparency and Card Configuration

    The muxponder card enables cost-effective, point-to-point delivery of any combination of 10-Gbps services by the Cisco ONS 15454 MSTP.

    The card can be provisioned in two operational modes: OTU3 Trunk or OTU3e Overclocked Trunk.

    In the first operational mode card can transparently multiplex any mix of STM-64/OC-192, 10GE LAN, 10GE WAN, OTU2, 8-Gbps Fibre Channel signals while in the second operational mode it is possible to combine any mix of 10-Gbps Fibre Channel and OTU2e (G,Sup43 7.1 and 7.2) signals as indicated in Table 1.

    The card is also able to provide provisionable SONET/SDH overhead bytes processing. It is possible to pass them transparently or to terminate the line and section overhead. In transparent mode, client terminal equipment interconnected over a muxponder-card-based circuit can communicate over the section/multiplexer section data communications channel (SDCC/MSDCC), can signal 1+1 and bidirectional line switched ring/multiplex section shared protection ring (BLSR/MS-SPR) protection switching using the K1 and K2 bytes, and can support provisionable section trace capabilities over the J0 byte. In addition, the muxponder circuit, whether provisioned in transparent or terminating mode, can support unidirectional path switched ring/subnetwork connection protection (UPSR/SNCP)-based client circuits.

    Full transparency is provided by the enhanced multiplex engine that performs the multiplexing of the incoming 10-Gbps signals at the OTN layer no longer in the SONET/SDH domain. Different mapping schemes are used depending on the payload to help ensure full transparency of the signal, as indicated in Table 1.

    LAN-to-WAN Conversion

    The Cisco 4-Port 10-Gbps Full-Band Tunable DQPSK Muxponder Card provides the capability to convert incoming 10 Gigabit Ethernet LAN PHY signal into 10 Gigabit Ethernet WAN PHY signal at the far-end egress port.

    The 10 Gigabit Ethernet LAN PHY-to-WAN PHY conversion is implemented according to standards defined in IEEE 802.3: WIS (WAN Interface Sublayer). 10 Gigabit Ethernet LAN PHY has an effective line rate of 10.3125 Gbps (10 Gbps of data traffic encoded in a 64B/66B protocol). 10 Gigabit Ethernet WAN PHY interfaces conform to the SONET/SDH standards to achieve 9.95328 Gbps and allow service providers to use their existing SONET/SDH Layer 1 infrastructure.

    WAN PHY is used to transport 10 Gigabit Ethernet across SDH/SONET or WDM systems without having to directly map the Ethernet frames into SDH/SONET first. The WAN PHY variants correspond at the physical layer to 10GBASE-SR, 10GBASE-LR, 10GBASE-ER, and 10GBASE-ZR respectively, and hence use the same types of fiber and support the same distances.

    Wavelength Tunability

    The muxponder cards operate on the 50-GHz ITU grid and are tunable across 82 adjacent 50-GHz channels for the C-band module and across 80 adjacent 50-GHz channels for the L-band module. The incorporation of tunability into the muxponder cards reduces the customer’s inventory required to cover all of the wavelengths for deployment and spares. Tunability is software-provisionable.

    Flexible Protection Mechanism Support

    The muxponder card, depending upon the requirement of the network, can be deployed to support the many protection mechanisms found in optical transport networks. Table 2 outlines the supported protection options that help to deliver the service-level agreements (SLAs) required by the application.

    Table 2. Protection Formats

    Protection Type



    No client terminal interface, muxponder card, or DWDM line protection. The client signal is transported over a single unprotected muxponder card.

    1+1 protection or UPSR/SNCP and BLSR/MSP‑SPR

    Provides protection for the client terminal interface, muxponder card, and DWDM line through client automatic protection switching/linear multiplex section protection (APS/LMSP) signaling transported transparently over the muxponder card.

    Similar to unprotected format. Protection is provided through client line or path protection via transparent signal transport through muxponder circuit.

    Y-cable protection

    Provides muxponder card and DWDM line protection without requiring client terminal equipment interface protection. Uses Y-protection device to optically split a single client interface to two muxponder cards. The Cisco ONS 15454 system controls the muxponder card active/standby status to provide a single signal feed to client equipment.

    OCH-trail protection

    Provide protection for DWDM signal through external optical switch units (PSM).


    Flexible Timing Options

    The Cisco 4-Port 10-Gbps Full-Band Tunable DQPSK Muxponder Card times the client side and the DWDM line optical transmitter port with the clock derivate by the shelf processor. The Cisco ONS 15454 platform provides the option to recover timing signals for node-timing reference, with sync status messaging support, from any of the four client optical interfaces in the case of SONET/SDH, Ethernet, and OTN signal, in addition to the standard options of using an external clock derived from a building integrated timing supply (BITS) clock or another optical interface card on the Cisco ONS 15454 system. The muxponder card is also able to recover the clock from the trunk when the operational mode is OTU3. The muxponder card can also maintain synchronization from an internal clock even if both the shelf processors (active and standby) fail.


    The Cisco ONS 15454 MSTP provides comprehensive management capabilities for operations, administration, maintenance, and provisioning (OAM&P) accessed through the integrated Cisco Transport Controller craft interface with support from the Cisco Transport Manager element management system (EMS). The muxponder card incorporates provisionable digital wrapper (G.709) functions, providing DWDM wavelength performance-management capabilities, especially for services being transported transparently across the network. Without the digital wrapper function, a carrier transporting a service transparently would be unable to identify network impairments that may degrade thetransported signal and exceed SLA requirements. The digital wrapper’s general communication channel (GCC) provides a separate communications channel, versus the section DCC/regenerator section DCC (SDCC/RSDCC) in SONET/SDH signals, to be used by the platform when transparent signals are transported. This GCC enables the Cisco ONS 15454 to extend its advanced network auto-discovery capabilities to DWDM-based services. The integrated Cisco Transport Controller craft manager and the Cisco Transport Manager EMS provide the user with OAM&P access for the system.

    Far-End-Laser-Off Behavior

    The Cisco 4-Port 10-Gbps Full-Band Tunable DQPSK Muxponder Card offers the capability to provision the Far-End-Laser-Off behavior in case of SONET/SDH payloads. The Cisco Transport Controller can be used 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).

    In the case of data signals (10 Gigabit Ethernet, 10 Gigabit Fibre Channel, or 8 Gigabit Fibre Channel) the behavior is squelching. In the case of OTN signals, the behavior is standard ODUk-AIS.

    Performance Monitoring

    The performance monitoring capabilities of the muxponder card provide support for both transparent and nontransparent signal transport. For SONET/SDH signals, standard performance monitoring, threshold-crossing conditions, and alarms are supported per Telcordia GR-253, GR-474, and GR‑2918, as well as ITU G.828 and ETS 300 417-1 standards. Each digital wrapper channel will be monitored per G.709 (OTN), G.8021. Optical parameters on the client and DWDM line interfaces support loss of signal (LOS), laser bias current, transmit optical power, and receive optical power. Calculation and accumulation of the performance monitoring data is in 15-minute and 24-hour intervals as per G.7710. Ethernet data are monitored using RMON.

    Table 8 provides a detailed list of performance monitoring parameters.

    The muxponder 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 the card can be installed.

    Regenerator Configuration

    The Cisco 4-Port 10-Gbps Full-Band Tunable DQPSK Muxponder Card also supports the OTU3 Regeneration function. Two cards can be configured to work in unidirectional mode, allowing the OTN O-E-O Regeneration function to perform, as shown in Figure 4.

    Figure 4. Unidirectional Configuration for 40-Gbps Muxponder Card in Regeneration Mode


    OTU overhead is terminated and ODU is correctly passed through as required by the G.709 standard, and GCC-1 and GCC-2 are properly passed through while GCC0 is not terminated.

    Application Description

    The Cisco ONS 15454 MSTP 4-Port 10-Gbps Full-Band Tunable DQPSK Muxponder adds the capability to cost-effectively aggregate 10-Gbps services and transparently transport them.

    Continued proliferation of data-intensive enterprise services (virtual offices with video conferencing, VPNs, etc.) and mass market deployment of high-end consumer applications (HD VoD, IPTV, etc.) are creating bottlenecks in the 10-Gbps-based DWDM transport network. Cisco’s 40-Gbps solution can quadruple the available fiber transport bandwidth with performances comparable to the 10-Gbps one.

    Fiber relief is one of the key applications for the Cisco 40-Gbps muxponder solution. Bandwidth transport demand increased in the last 3 years consuming existing 10-Gbps Wavelength base DWDM system. With the 40-Gbps muxponder it is possible to significantly increase existing DWDM system capacity. Operators can upgrade an existing 80-channel 10-Gbps network equipped with 64 wavelengths with an additional 16 wavelengths at 40 Gbps that carry an additional 64 10-Gbps signals, thanks to the 40-Gbps muxponder. The Cisco solution was specifically designed to support existing 10-Gbps channels without any need to upgrade the existing optical infrastacture.

    Industry trends show that the adoption of 8-Gbps Fibre Channel has become critical in data center environments due to the increase of SAN services (server virtualization, etc.). The 40-Gbps muxponder card offers a hyper-dense 8-Gbps Fibre Channel solution, enabling operators to transmit over a single fiber pair up to 320 8-Gbps Fibre Channel signals over the C-band.

    Figure 5. Data Center 8-Gbps Fibre Channel over 40-Gbps Muxponder Card – Architecture


    The LAN-WAN conversion on the muxponder card allows the service flexibility to accommodate existing SONET/SDH OC-192/STM-64 facilities that are mapped for 10 Gigabit Ethernet payloads. Key applications are the transport of 10 Gigabit Ethernet over traditional SONET/SDH networks and submarine landing side translation where the vast majority of the systems are TDM-only-based.
