CISCO ONS 15600 SERIES 16-PORT 2.5-GBPS OPTICAL INTERFACE CARDS
The Cisco® ONS 15600 Series Multiservice Switching Platform (MSSP) offers the industry's highest-density short-reach/short-haul (SR/SH) and long-reach/long-haul (LR/LH) OC-48/STM-16 optical interface cards, allowing users to build cost-effective networks by matching the appropriate interface to the requirements of the network application (Figure 1).
Cisco ONS 15600 Series MSSP and 16-Port OC-48/STM-16 LR/LH and SR/SH Cards
Fully Cisco designed and engineered, the Cisco ONS 15600 Series MSSP simplifies and revolutionizes bandwidth management in the metropolitan-area (metro) core by allowing service providers to transparently integrate their metro core and metro edge networks, while dramatically reducing initial turn-up costs. The Cisco ONS 15600 Series MSSP combines the functions of multiple metro systems, including SONET/SDH multiplexers and digital cross-connect network elements, together in one scalable, easy-to-use platform with carrier-class reliability, availability, serviceability, operations, and management.
The OC-48/STM-16 capabilities on the Cisco ONS 15600 Series consist of two optical line cards, providing interface specifications that meet the varied application needs of the service provider. Table 1 outlines the new Cisco ONS 15600 Series 16-Port OC-48/STM-16 Short-Reach/Short-Haul Interface Card and the Cisco ONS 15600 Series 16-Port OC-48/STM-16 Long-Reach/Long-Haul Interface Card now available for the Cisco ONS 15600 Series, and the applications they are designed to support.
Table 1. OC-48/STM-16 Interface Cards with Applications
SR/SH interface card
Suitable for metro regional or interoffice connections between central offices with span lengths of less than 2 km
LR/LH interface card
Suitable for metro regional or interoffice connections between central offices with span lengths between 40 and 80 km
Both interface cards provide 16 transmit and 16 receive optical interfaces in a single-slot footprint within the Cisco ONS 15600 Series shelf assembly. Each port interface operates at the standard SONET/SDH (Telcordia GR-253-CORE and ITU G.703) 2.4883-Gbps bit rate. The SR/SH and LR/LH OC-48/STM-16 cards use four OGI connectors on the card faceplate that are routed through a cable-routing module (CRM) to SC, ST, or FC terminations. The cards carry both 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 and non-concatenated payloads on an STS-1 basis. In SONET mode, each optical port can be provisioned as STM-16 to enable the tunneling of SDH payloads in the form of STS-Nc concatenated payload over a SONET network. This helps enable North American service providers to transport SDH traffic from international cable landing points to customer sites. When operated within the outlined specifications (refer to Table 4), each port interface transports a 2.5-Gbps signal with a minimum bite error rate (BER) of 10E-12.
The OC-48/STM-16 SR/SH and LR/LH cards are deployable in any of the eight multiservice slots (slots 1-4 or slots 11-14) of the Cisco ONS 15600 Series platform. A maximum of 128 OC-48/STM-16 SR/SH and LR/LH ports can be supported on a single Cisco ONS 15600 Series shelf. The cards can be commissioned for use in unidirectional-path switched ring/subnet work connection protection (UPSR/SNCP), 2-fiber bidirectional line switched ring/multiplex section-shared protection ring (BLSR/MS-SPR), 1 + 1 automatic protection switching/multiplex section protection (APS/MSP), or path-protected mesh network (PPMN) architectures, offering service providers the flexibility to build the type of network required to meet their service demands, traffic patterns, and user needs. This card-provisioning flexibility also helps reduce the cost of inventory and simplifies engineering and deployment.
The OC-48/STM-16 SR/SH and LR/LH cards incorporate faceplate-mounted LEDs to provide a quick visual check of the operational status at the card. Printed on the faceplate is an icon, an orange circle, which indicates the shelf slot where the card can be physically installed. The card is supported by the integrated Cisco ONS 15600 Series Cisco Transport Controller Craft Manager, which provides the user access for operations, administration, maintenance, and provisioning (OAM&P) for the system.
