The 12-Port and 4-Port SFP-Based Multirate Optics Card for the Cisco® ONS 15454 Multiservice Provisioning Platform (MSPP) improves the platform's system flexibility, scalability, and economics in multiple-port optical configurations.
Product Overview
The Cisco ONS 15454 12-Port and 4-Port SFP-Based Multirate Optics Card (MRC-12 and MRC-4) supports multiple Small Form-Factor Pluggable (SFP) modules, helping enable multirate SONET/SDH and multiple-reach capabilities. The MRC-12 card (Figure 1) operates in either Cisco ONS 15454 SONET or SDH systems, supporting optical line rates including OC-3/STM-1, OC-12/STM-4, and OC-48/STM-16 and optical reaches from short-reach/interoffice to long-reach/long-haul, including dense wavelength-division multiplexing (DWDM) and coarse wavelength-division multiplexing (CWDM). There are two versions of the MRC-12 card for SDH systems, limited to 10 Gbps and 2.5 Gbps of bandwidth capacity, respectively. The MRC-4 (Figure 2) operates only in Cisco ONS 15454 SONET systems, but at the same optical line rates and optical reaches, with up to 2.5 Gbps bandwidth.

Figure 2. MRC-4 Card
The MRC cards, depending upon the selected SFP, can carry concatenated payloads of STS-3c/VC-4, STS-6c/VC-4-2c, STS-12c/VC-4-4c, STS-24c/VC-4-8c, and STS-48c/VC-4-16c as well as nonconcatenated payloads on an STS-1, VC-4, VC-3, VC-12, VC-11, and VT1.5 basis. In SONET applications, the cards are software-provisionable to transport SDH payloads over SONET in the form of STS-Nc-concatenated payloads. When operated within the outlined specifications, each card transports signals with a maximum bit error rate of 1 per trillion.
The MRC cards are deployable in any of the 12 service interface card slots of the Cisco ONS 15454 MSPP. Their bandwidth also depends upon the cross-connect card operating within the system as well as the interface slot where the cards are installed. Their ports can be commissioned for use in four different architectures - unidirectional-path switched ring/subnetwork connection protection (UPSR/SNCP), 2-fiber and 4-fiber bidirectional line switched ring/multiplex section-shared protection ring (BLSR/MS-SPR), 1+1 automatic protection switching/line multiplex section protection (APS/LMSP), or path-protected mesh network (PPMN) - providing the flexibility to build the type of networks required to meet service demands, traffic patterns, and user needs. This card-provisioning flexibility also helps to reduce the cost of inventory and simplifies engineering and deployment.
The MRC cards provide in-service upgrade capabilities from single-port optics cards utilizing the same service slot. They also support line-rate span upgrades through the upgrading of an SFP module.
The cards incorporate faceplate-mounted LEDs to provide a quick visual check of the operational status at the card as well as the individual ports. The fan-tray-mounted liquid crystal display (LCD) and soft keys provide the technician local access to the wavelength of each DWDM or CWDM optical port without the need to access the craft manager. Printed on the faceplate is an orange circle icon, which indicates the shelf slot where the card can be physically installed.
The card is supported by the integrated Cisco Transport Controller craft manager for the Cisco ONS 15454 MSPP. The controller provides the user with access to operations, administration, maintenance, and provisioning for the system. Access to inventory data for the installed MRC card and pluggable optics modules is available through the craft manager, the Cisco Transport Manager element management system, and Transaction Layer 1 requests.
The SFP modules used with the MRC cards are SONET/SDH-compliant (Telcordia Technologies GR-253-CORE and ITU G.957) optical interfaces. The transmitter and receiver reside on the same module and are interconnected to the fiber using small form-factor LC connectors. The SFP modules in the MRC cards support provisionable automatic laser shutdown feature (ITU G.664) to turn off the transmitting laser in the event of a fiber failure on the span. The SFP optical parameters, including laser bias current, optical transmit power, and optical receive power, are available through Cisco Transport Controller to enable simplified troubleshooting and advanced warning of potential impending issues using user-configurable high and low threshold crossing alerts. The SFP cages are angled down relative to the faceplate to reduce bend-induced stresses on the optical fibers exiting the faceplate.
The Cisco ONS 15454 12-Port Multirate Optics Card adds significant value to users' networks by enhancing system flexibility, improving card-slot usage of the shelf assembly, reducing intershelf complexity, and lowering system cost.
Applications
A Cisco ONS 15454 MSPP equipped with an MRC card provides application solutions for both service providers and enterprise managers, including the two following examples.
Multiservice Aggregation and Transport System
The high-port-density and multiple-reach support of the MRC-12 card requires fewer cards to perform the same function as multiple fixed-rate/reach cards (Figure 2).
Figure 3. MRC-12 Card Frees Up Cisco ONS 15454 Shelf Slots
The Cisco ONS 15454 shelf slots that are freed up by the MRC-12 card can be used for additional revenue-generating services, such as Fibre Channel, 10/100/1000 Mbps Ethernet, and so on (Figure 4).
Figure 4. MRC-12 Card Opens Up New Revenue Opportunities
The MRC-12 card also lowers the capital expenditure cost of the Cisco ONS 15454 system by using many optical ports on a common carrier-based card.
Network Consolidation Node
Reducing network complexity and lowering capital expenditures is a primary need of many businesses. The high port density and multiple-reach support through pluggable optics modules enables users to consolidate network elements as well as simplify operations by reducing internetwork element cabling. Figure 5 shows a traditional service provider network, with access and interoffice networks collecting and transporting traffic. Figure 6 shows the same network using the high-density MRC-12 card.
Figure 5. Typical Network Design
Figure 6. Network Consolidation Design with MRC-12 Card
The high-density MRC-12 card with its flexible optical rate and reaches helps consolidate many network elements and significantly reduce the complexity of interworkings between the various networks. Manual cabling by an onsite technician is replaced by electronic cross-connections using the Cisco Transport Controller craft management system from anywhere with network connectivity. This helps improve response times to circuit additions and changes.
With its flexibility, density, and wide selection of service modules, the Cisco ONS 15454 MSPP supports a comprehensive mix of applications, allowing a single platform type to meet many business requirements. These capabilities allow users to lower their operational costs by reducing technician training to a smaller base of platform types, reducing sparing requirements, and decreasing service turn-up time for improved revenues.
