12-port SFP-based multirate optics card, intra-office, SONET systems
Cisco 15454-MRC-I-12. Product type: MSPP, Standard interfaces: SONET. Power consumption (typical): 25 W. Weight: 1.22 kgThe 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.
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 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 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.
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.
