The 10-Gbps Multirate Enhanced Transponder Card for the Cisco® ONS 15454 Multiservice Transport Platform (MSTP) simplifies the integration and transport of 10 Gigabit Ethernet, 10 Gigabit Fibre Channel, OC-192, and STM-64 interfaces and services into enterprises or metropolitan-area (metro) and regional service provider networks (Figure 1).

Figure 1. Cisco ONS 15454 10-Gbps Multirate Transponder Card

Background

Metro transport networks must support numerous service demands, from low-rate DS-1/T1, DS-3/E3, 10/100BASE-T, and OC-3/STM-1 to higher-rate OC-12/STM-4, Gigabit Ethernet, OC-48/STM-16, OC-192/STM-64, and 10 Gigabit Ethernet services. In the recent past, SONET add-drop multiplexers (ADMs) provided the services platform to aggregate and transport services up to OC-48/STM-16, whereas metro dense wavelength-division multiplexing (DWDM) platforms were designed for optical signals from OC-3/STM-1 to OC-192/STM-64, including Gigabit and 10 Gigabit Ethernet. Unfortunately, deploying multiple platforms (including metro DWDM and SONET ADMs) to support multiple services is not cost-effective for many service provider and enterprise networks. The Cisco ONS 15454 MSTP with a muxponder card provides a more cost-effective networking solution to enable the delivery of all services, from lower-speed DS-1/E1, high-density 2.5 Gbps, and high-bandwidth OC-192/STM-64.

Product Overview

The 10-Gbps Multirate Transponder Card can transport 10 Gigabit Ethernet WAN physical layer (PHY) and LAN PHY, 10 Gigabit Fibre Channel, SONET OC-192, and SDH STM-64 services over a 100-GHz spaced, 50-GHz stabilized, ITU-compliant wavelength. The transponder card is a plug-in module to the Cisco ONS 15454 MSTP, enabling a cost-effective architecture for delivering high-rate 10-Gbps services as well as low-rate services down to 1.5 Mbps. The transponder card architecture contains a single client interface that is mapped to a single line interface, without accessing the Cisco ONS 15454 shelf cross-connect fabric.

The client interface supports 10 Gigabit Ethernet LAN PHY, 10 Gigabit Ethernet WAN PHY, 10 Gigabit Fibre Channel, SONET OC-192, and SDH STM-64 signals. The interface is based on 10 Gigabit Small Form-Factor Pluggable (XFP) Multisource Agreement (MSA). Currently available XFP optics support a short-reach/intra-office, 1310-nanometer (nm) optical interface using LC connectors supporting fiber distances of up to 2 kilometers (km) (with or without the Y-protection option).

The line interface provides one 10-Gbps, long-reach, ITU-compliant, 100-GHz-spaced optical interface using LC connectors supporting OUT-2 G.709 digital wrapper, OC-192, STM-64, 10 Gigabit Fibre Channel, 10 Gigabit Ethernet LAN PHY, or 10 Gigabit Ethernet WAN PHY interfaces. The DWDM output line interface is tunable across four adjacent 100-GHz wavelengths, enabling support for 32-channel DWDM networks through eight discrete card types. When operated within the outlined specifications, each card will transport the 10-Gbps signal with a maximum bite error rate (BER) of 10E-15.

The 10-Gbps transponder card incorporates both a client and DWDM line interface on the same card. The 10-Gbps transponder cards are deployable in the 12 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 asaggregation of other services supported by the Cisco ONS 15454 platform. The only required common card is the appropriate timing, communications, and control card (TCC).

The 10-Gbps transponder card provides many carrier-class features and advanced capabilities necessary to deliver 10-Gbps services, including the protocol transparency, wavelength tunability, flexible protection mechanisms, flow-through timing, management, and performance monitoring capabilities outlined below.

Enhanced FEC Capability

An important feature of the transponder card is the availability to configure the Forward Error Correction (FEC) in three modes: NO FEC, FEC, and E-FEC. The output bit rate will depend on the bit rate of the incoming signal but the digital wrapper will be always as defined in G.709.

10.70923 Gbps in case of OC-192/STM-64/10GE WAN

11.095 Gbps in case of 10GE LAN PHY (over-clocking mode)

11.3168 Gbps in case of 10G FC (over-clocking mode)

Error-coding performance can be provisioned:

NO FEC: no Forward Error Correction

FEC: standard G.975 Reed-Salomon algorithm

E-FEC: standard G.975.1 two orthogonally concatenated BCH super FEC code. 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.

Protocol Transparency

The 10-Gbps transponder card provides transparent wavelength services on the Cisco ONS 15454 platform. For SONET- or SDH-based client payloads, when provisioned in transparent operating mode, the card will pass all of the SONET/SDH overhead bytes transparently. The card monitors important SONET/SDH overhead bytes, such as B1 (section BIP-8) and J0 (section trace), to allow fault isolation and performance monitoring capabilities. Termination of the line data communications channel (LDCC) is user-provisionable, to enable the platform processor to route the DCC information for intracarrier networking or to allow the DCC information to be transported untouched, through the digital wrapper’s general communications channel (GCC), for intercarrier networking. For 10 Gigabit Ethernet and OC-192/STM-64 payloads, digital wrapper technology (G.709) is used to add a management wrapper to the service, allowing the transponder card to transparently forward the payload while enabling performance metrics to be derived to ensure circuit service quality.

The card is transparent to the embedded payload and does not access the Cisco ONS 15454 platform’s cross-connect. It can carry any type of concatenated SONET/SDH payloads (STS-Nc or VC-4-Mc), nonconcatenated payloads on an STS-1, VC-4, VC-3, VC-12, or VT1.5 basis, and10 Gigabit Ethernet LAN or WAN PHY payloads.

Wavelength Tunability

The 10-Gbps transponder cards operate on the 100-GHz ITU grid and are tunable across four adjacent 100-GHz channels per card. The incorporation of tunability into the transponder cards reduces the customer’s inventory required to cover all of the wavelengths for deployment and spares. Tunability is software-provisionable.

Flexible Protection Mechanisms

The 10-Gbps transponder card provides flexible protection capabilities for both client and DWDM line interfaces, enabling support for numerous network configurations required to meet the various service-level agreements (SLAs) for customer applications (Table 1).

Table 1. Protection Formats

Protection Type

Capabilities

Figure

Unprotected client and line

No client terminal interface, transponder card, or DWDM line protection. The client signal is transported over a single unprotected transponder card. This configuration is suitable for transporting client payloads over a DWDM network that is being protected via unidirectional path switched ring/subnetwork connection protection (UPSR/SNCP) or bidirectional line switched ring/multiplex section shared protection ring (BLSR/MS-SPR) protocols.

2

1+1 protected client

Enables protection for both the client terminal interfaces and the transponder cards. Two client terminal interfaces operating 1+1 automatic protection switching/multiplex section protection (APS/MSP) switching are passed through 2 transponder cards, with switching managed between client terminal equipment interfaces.

3

Y-cable client interface

Provides transponder equipment protection without client terminal equipment interface protection. A single client interface is split to 2 transponder cards using a Y-protection device.

Flow-Through Timing

The transponder card allows the timing to “flow through” from client to line optical interfaces. Receive timing from one interface (client or line) is used to time the other transmitter interface (line or client). This flow-through timing enables the transported signal to remain independent from the node timing.

Management

The Cisco ONS 15454 MSTP provides comprehensive management capabilities to support the operations, administration, monitoring, and provisioning (OAM&P) capabilities through the integrated Cisco Transport Controller craft interface with support from the Cisco Transport Manager element management system (EMS). The transponder card incorporates provisionable digital wrapper (G.709) functions, providing per-wavelength performance management capabilities, especially for services being 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 exceed SLA requirements. The digital wrapper’s GCC enables a separate communications channel on a per-wavelength basis, versus the section DCC/regenerator section DCC (SDCC/RSDCC) in SONET/SDH signals that is used by the platform when transparent signals are transported. This GCC enables the Cisco ONS 15454 to extend its advanced network autodiscovery 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.

Configurable Far-End-Laser-Off Behavior

The 10-Gbps Multirate Enhanced Transponder Card offers the capability to provision the Far-End-Laser-Off behavior. You 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).

Performance Monitoring

The performance monitoring capabilities of the 10-Gbps transponder card provide support for both transparent and nontransparent signal transport. For SONET/SDH-terminated signals, standard performance-monitoring and threshold-crossing conditions and alarms are supported per Telcordia GR-474, GR-2918, ITU G.783, and ETS 300 417-1 standards. For 10 Gigabit Ethernet signals, standard performance parameters for transmit and receive signals are based on RFC 2819. Each digital wrapper channel will be monitored per ITU-T digital wrapper requirements (G.709). Optical parameters on the DWDM line interface are supported, including laser bias, transmit optical power, and receiver optical power. Calculation and accumulation of the performance monitoring data will be in 15-minute and 24-hour intervals.

The transponder cards incorporate 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 slots the card can be installed.

Application Description

The 10-Gbps transponder card adds several new applications to an already flexible Cisco ONS 15454 platform. These applications include metro 10 Gigabit Ethernet connectivity, STM-64 transport for cable-landing service extension, and OC-192/STM-64 transport for carrier services.

Metro 10 Gigabit Ethernet connectivity (Figure 5): With the addition of 10 Gigabit Ethernet on data terminals, the need for service providersto add a 10 Gigabit Ethernet transport service becomes critical to provide a complete metro service portfolio to their customer base. The 10-Gbps transponder card helps enable service providers to cost-effectively integrate 10 Gigabit Ethernet into their metro service mix over amultiservice network, reducing the need to deploy an overlay metro DWDM platform, and reducing the cost to deploy the service.

Figure 5. Metro 10 Gigabit Ethernet Connectivity

STM-64 transport for cable-landing service extension (Figure 6): A second application is the capability of a carrier’s service provider (Service Provider A) to transport STM-64 payloads from a transoceanic cable-landing site to another service provider’s international gateway site (Service Provider B).

Figure 6. STM-64 Transport for Cable-Landing Service Extension

OC-192/STM-64 transport for carrier services (Figure 7): The OC-192/STM-64 transport for a carrier’s carrier services is similar to the application outlined in Figure 6.

Figure 7. OC-192/STM-64 Transport for Carrier Services

In each of these applications, the user can provide several service types, from DS-1/E1 to 10-Gbps services using a single transport platform, for example, the Cisco ONS 15454 MSTP, reducing system complexity, capital expenditures, and operational expenses related to technician training.

The Cisco Advantage

The Cisco ONS 15454 10-Gbps Multirate Enhanced Transponder Card complements and extends the service capabilities of the Cisco ONS 15454 MSTP. The card enables carriers to take advantage of their existing fiber plant and installed base of Cisco ONS 15454 systems, while providing the required services, such as DS-1/E1, DS-3/E3, OC-n/STM-n, Ethernet, ATM, and video over the same Cisco ONS 15454 platform. The solution reduces the need to deploy an overlay metro DWDM platform to transport a mixture of services (Figure 8 and Figure 9).

Figure 8. Today’s DWDM Architecture

Figure 9. Cisco ONS 15454 Hybrid DWDM Architecture

The Cisco ONS 15454 optical transport solution offers significant advantages over traditional network elements offering 10-Gbps interfaces, including the following.

Unprecedented Service Densities

The Cisco ONS 15454 platform supports up to 12 10-Gbps interfaces per node. When the platform is installed in a typical central office bay frame, a bay can support up to 48 10-Gbps interfaces. These industry-leading densities are attainable because of the single-slot footprint of the transponder interface card.

Multiple Restoration Types

The Cisco ONS 15454 platform supports 2- or 4-fiber BLSR/MS-SPR, UPSR/SNCP, linear APS/SNC, and path-protected mesh networking (PPMN). This allows the service provider to deploy the platform in all areas of the transport networking applications, including the interoffice network, normally deployed using 2- or 4-fiber BLSR/MS-SPR restoration, as well as the collector or fiber to the building networks, normally using UPSR/SNCP restoration.

Common Line Cards

Optical line cards are not restoration-type-dependent, which reduces sparing costs and technician confusion. Additionally, as networks and customer interface demands evolve, you can easily redeploy optical circuit packs as necessary.

Single Software Load

One software load supports all restoration types listed previously, eliminating unnecessary guesswork when ordering. All protection configurations are covered under a single right-to-use software license. After the software is purchased, all features and full functions are available to the user.

Common Chassis

A common chassis supporting all optical interface speeds allows the technician to spend time deploying bandwidth and services instead of learning about multiple equipment platforms. Many equipment vendors offer optical line-speed specific platforms (for example, OC-3/STM-1 or OC-12/STM-4) and categorize platforms by restoration mechanisms (for example, UPSR/SNCP, 2F-BLSR/MS-SPR, and 4F-BLSR/MS-SPR). This not only causes ordering confusion, but brings into question whether the inventoried equipment will accommodate the functionality required to support the desired application. The Cisco ONS 15454 platform’s line-rate and restoration flexibility makes ordering and deploying simple, fast, and easy.

Multiservice Interface Selection

DS-1/E1 through OC-192/STM-64, Ethernet, Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet interfaces are all supported. This eliminates the “missing interface” found with many vendors’ bit-rate-specific product offerings.

The Cisco ONS 15454, the industry’s leading metro optical transport platform, delivers supercharged SONET/SDH transport, integrated opticalnetworking, unprecedented multiservice interfaces, and competitive economic benefits.
