service types, including Enterprise Systems Connection (ESCON), Fibre Channel,
Gigabit Ethernet, SONET/SDH (to 2.5 Gbps), and video interfaces and services
into enterprise as well as metropolitan (metro) and regional service provider
Metro transport networks must support a wide variety of service demands, from low-rate DS-1/E1, DS-3/E-3, 10/100BASE-T, OC-3/STM-1, etc., to higher-rate OC-12/STM-4, Gigabit Ethernet,
OC-48/STM-16, 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, where 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 platform types, including metro DWDM and
SONET ADMs, to support the wide variety of services is not cost effective for many service
provider and enterprise networks. Thus, a more cost-effective networking solution is required to
enable the delivery of all services, from lower-speed DS-1/E-1s to higher-speed 10 Gigabit
Ethernet and OC-192/STM-64s.
The 2.5-Gbps multirate transponder (2.5G transponder) card (Figure 1) provides the capability to transport a wide variety of service types from
155 Mbps to 2.48 Gbps, including services such as ESCON, SONET OC-3 through OC-48, SDH STM-1 through STM-16, Gigabit Ethernet, 1or 2-Gbps Fibre Channel, and other services, over a 100-GHz, ITU-compliant wavelength, with 50-GHz wavelength stability for future 64channel operation. The 2.5G transponder card architecture contains a single client interface that is mapped to a single-line DWDM interface,
without accessing the Cisco ONS 15454 shelf cross-connect fabric.
The interface to the client is via a variety of Small Form-Factor Pluggable (SFP) optics modules, enabling a wide service mix, including
ESCON, OC-3/STM-1, OC-12/STM-4, OC-48/STM-16, Gigabit Ethernet, 1-Gbps Fibre Channel/FICON, 2-Gbps Fibre Channel/FICON, as
well as high-definition television (HDTV), D1/SDI video, DV6000, and different fiber types (single- and multimode), wavelengths (850 and
1310 nm), and fiber reach (short reach/intra-office, intermediate reach/short haul, etc.). The SFP optics modules are equipped with LC
connectors to enable high-density placement on the card.

The DWDM line interface provides one long-reach/long-haul (LR/LH), ITU-compliant, 100-GHz spaced optical interface, with a 50-GHz
wavelength stability, using LC connectors; it operates at line rates of up to OC-48 plus G.709 overhead. The DWDM output line interface is
tunable across four adjacent 100GHz wavelengths, enabling support for 32-channel DWDM networks using eight discrete card types. Each 2.5G
transponder card wavelength is offered in protected or unprotected versions, with the protected version including a second DWDM line
output/input, enabling optical line protection over a DWDM network. Taking advantage of amplification and dispersion compensation, the 2.5G
transponder card is capable of optical reaches exceeding 500 km. When operated within the outlined specifications with forward error correction
enabled, the card delivers the client payload with a bite error rate (BER) up to 10E-15 (refer to Table 1).
The 2.5G transponder card incorporates both client and DWDM line interfaces on the same card. The 2.5G 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 only common
card type required for operation is the timing, communications, and control card in MSTP system deployments. The addition of a cross-connect
card to the Cisco ONS 15454 system, beginning with Release 4.6 software, enables support of hybrid applications, further enabling a mixture of
transparent 200-Mbps to 2.5-Gbps services as well as aggregated services via the cross-connect card to other transport cards.
The 2.5G transponder card supports many carrier-class features and advanced capabilities necessary to deliver the wide service mix, including
provisionable protocol transparency, wavelength tunability, flexible protection mechanisms, flow-through timing, management, and
performance-monitoring capabilities outlined in the following sections.
Provisionable Protocol Transparency
The 2.5G transponder card is designed to support both transparent wavelength and nontransparent services on the Cisco ONS 15454 platform
via three operating modes, 2R, 3R, and 3R+. In 2R mode, the 2.5G card passes data transparently between the client interface and the DWDM
line interfaces, and conversely. The data may vary at bit rates for 155 Mbps to 2.5 Gbps, and includes ESCON and video signals (HDTV, D1,
and C-Cor DV6000). The 2R mode regenerates and reamplifies the inbound signal, but does not provide retiming.
The 2.5G transponder card in 3R mode provides inbound signal regeneration, reamplification, and retiming. The data bit rates supported are
from 155 Mbps to 2.488 Gbps and include SONET/SDH OC-3/STM-1, OC-12/STM-4, and OC-48/STM-16 signals, 1- and 2-Gbps Fibre
Channel and FICON, and Gigabit Ethernet.
The 2.5 transponder card in 3R enhanced mode maps the client signal over G.709 with integrated forward error correction (FEC) for transparent
service support for the 3R signals outlined earlier. The G.709 technology provides an envelope the payload and provides a SONET/SDH-like
layering structure that provides in-service performance monitoring, protection, and optical management functions. This 3R+ mode improves
network performance and ultimately the reach of the system.
For SONET- or SDH-based client payloads, there are three operating modes, transparent (monitor only), line termination, and section
termination. When provisioned in transparent operating mode, the card passes all the SONET/SDH overhead bytes transparently. The card
monitors key SONET/SDH overhead bytes, such as B1 (section BIP-8) and J0 (section trace), to allow fault-isolation as well as performancemonitoring capabilities. Additionally, in transparent mode, in order to ensure network integrity, a client interface loss of signal or loss of frame
on one end of the network is transferred to the associated far-end client interface, shutting off the far-end laser. In line termination mode, the
client transport overhead (TOH) is terminated and the B1/B2 bytes are regenerated with appropriate remote indication signals inserted.
Wavelength Tunability
The 2.5G transponder cards operate on the 100-GHz ITU grid and are tunable across four adjacent 100-GHz channels per card, with 50-GHz
wavelength stability, allowing eight discrete cards to cover the entire 32-wavelength plan. The incorporation of tunability into the 2.5G
transponder cards greatly reduces the customer’s inventory to cover all the wavelengths for sparing needs.

Flexible Protection Mechanisms
The 2.5G transponder card provides flexible protection capabilities for both client and DWDM line interfaces, outlined in Table 1, enabling
support for a wide variety of network configurations required to deliver the various service-level agreements (SLAs) required by the customer
Table 1.
Protection Formats
Protection Type
Unprotected client and DWDM
line interfaces
These interfaces provide no client terminal interface or transponder card protection.
The client signal is transported over a single, unprotected transponder card. This
configuration would be suitable for transporting client payloads over the DWDM
network that are being protected via unidirectional-path switched ring/Subnetwork
Connection Protection (UPSR/SNCP) or Bidirectional Line Switch Ring/multiplex
switching protection-shared protection ring(BLSR/MSP-SPR) protocols.
Figure 2
1+1 protected client interfaces
These interfaces provide protection for both the client terminal interfaces as well as
the transponder cards. Two client interfaces operating 1+1 automatic protection
switching (APS) are passed through two transponder cards, with switching handled
between client terminal equipment interfaces.
Figure 3
Y-cable client interface
This interface provides transponder equipment and DWDM transport protection
without client terminal equipment interface protection. A single client interface is split
to two transponder cards. This feature is not supported on the protected version of the
transponder card.
Figure 4
Protected DWDM line interface
This interface provides network protection for a single client signal using the protected
version of the 2.5G transponder card. This card splits the outbound signal into two
wavelength paths. At the receiver end, the card selects the better of two input signals,
forwarding it to the client transmitter.

Flow-Through Timing
The transponder card allows timing to “flow through” from client to DWDM line optical interfaces. Recovered receiver timing from one
interface (client or line) is used to time the other transmitter interface (line or client). This enables the transported signal to remain independent
from the node timing.
The Cisco ONS 15454 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 2.5G transponder card incorporates provisionable G.709 functions for all 3R service
interfaces. G.709 functionality enables a carrier transporting a service transparently to identify network impairments that may degrade the
transported signal and exceed SLA requirements. The general communication channel (GCC) of the G.709 provides a separate communications
channel on a per-wavelength basis for the transparently transported service channels, as compared with the section data communication
channel/regenerator section data communications channel (SDCC/RSDCC) in SONET/SDH signals. This GCC enables the Cisco ONS 15454
to extend its advanced network autodiscovery capabilities to DWDM-based services. For SONET/SDH services, when termination mode is
used, SDCC can be used to enable similar function on the Cisco ONS 15454 SONET/SDH network element, allowing the capabilities to
manage both SONET/SDH and DWDM networks at the same time. The integrated Cisco ONS 15454 Cisco Transport Controller craft manager
as well as the complementary Cisco Transport Manager EMS provide the user access for OAM&P for the system.

Performance Monitoring
The performance-monitoring capabilities of the 2.5G transponder card depend on the service being transported. For 2R services, performance
monitoring is limited to that provided by the SFP, which includes received and transmit powers, laser bias current, inventory, and the DWDM
optical interface, including received and transmit powers and laser bias current. For 3R services, performance monitoring is available based on
the signal type, except for 2-Gbps Fibre Channel, which again is limited to the performance-monitoring statistics delivered by the SFP optics
module. For SONET/SDH signals, extensive performance-monitoring and threshold-crossing conditions and alarms are supported per Telcordia
GR-474 and GR-2918, as well as ITU G.783 and ETS 300 417-1 standards. For data applications, such as Gigabit Ethernet and 1-Gbps Fibre
Channel, 8b/10b performance monitoring is supported. Finally, the digital wrapper channel is monitored per ITU-T requirements (G.709 and
G.798). Optical performance parameters on the DWDM line interface are supported, including laser bias current and receiver optical power.
Calculation and accumulation of the performance-monitoring data are in 15-minute and 24-hour intervals.
The 2.5 transponder cards incorporate faceplate-mounted LEDs to provide a quick visual check as to the operational status at the card. Printed
on the faceplate is an icon, an orange circle, indicating that the shelf slots on the card can be physically installed.
The 2.5G transponder card adds numerous new applications to an already flexible Cisco ONS 15454 platform. One identified application
includes storage area networking (SAN) transport (Figure 6), providing connectivity between the primary and backup data centers for disaster
Figure 6
SAN Connectivity for Disaster Avoidance
Another application, detailed in Figure 7, is the transparent transport of SONET/SDH-based services, OC-48/STM-16 in this example, for a
carrier’s carrier service application.

advantage of the other supported interface types, including DS-n/E-n private line, D1/SDI and C-Cor DV6000 video, Ethernet, ESCON, and
The Cisco ONS 15454 2.5G Transponder Card complements and extends the services capabilities of the Cisco ONS 15454 platform. The 2.5G
transponder card enables users to deliver wavelength services over their existing fiber plant over a proven Cisco ONS 15454 platform that also
supports service aggregation, including DS-1/E-1, DS-3/E-3, OC-n/STM-n, and Ethernet. The Cisco ONS 15454 platform enables users to
reduce the need to deploy standalone metro DWDM and multiservice provisioning platforms (MSPPs) to transport a mixture of services, as
outlined in Figures 8 and 9.

Cisco ONS 15454 Hybrid DWDM Architecture
The Cisco ONS 15454 Optical Transport solution offers significant advantages over traditional network elements that offer broad deployment
and capabilities, including:
• Unprecedented service interface selection—The Cisco ONS 15454 platform supports the broadest range of service interfaces available on a
single chassis type by using software personality loads, including asynchronous (DS-1/E-1, DS-3/E-3), SONET/SDH (EC-1, OC-3/STM-1 to
OC-192/STM-64), Ethernet (10, 100, 1000, and 10,000 Mbps), SAN (ESCON, FICON, 1- and 2-Gbps Fibre Channel), and video (D1 and CCor DV6000) interfaces.
Multiple restoration types—The Cisco ONS 15454 MSPP platform supports two- or four-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 inter-office network, normally deployed using two- or four-fiber BLSR/MS-SPR restoration, as well
as the collector or fiber to the building networks, normally taking advantage of UPSR/SNCP restoration.
Common line cards and chassis—Optical line cards are not restoration-type dependent, reducing sparing costs and technician confusion.
Additionally, as networks change and customer interface demands evolve, the user has the ability to easily and simply redeploy optical
circuit packs as necessary.
Common chassis type—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
(OC-3/STM-1, OC-12/STM-4, and so on) and categorize platforms by restoration mechanisms (UPSR/SNCP, 2F-BLSR/MS-SPR, 4FBLSR/MS-SPR, etc.). This not only causes confusion when ordering, but also may bring into question whether the required platform will be
available to support the desired application. The line rate and restoration flexibility of the Cisco ONS 15454 makes ordering and deploying
simple, fast, and easy.
The Cisco ONS 15454, the industry’s leading metro optical transport platform, delivers supercharged SONET/SDH transport, integrated optical
networking, unprecedented multiservice interfaces, and competitive economic benefits.
