Product Overview
The 2.5-Gbps multiservice aggregation card provides service aggregation of Gigabit Ethernet, Fibre Channel, FICON, and ESCON services
over a 2.5-Gbps 100-GHz, ITU-compliant wavelength, with 50-GHz wavelength stability for future 64-channel operation. The card architecture
contains eight client interfaces that are electronically multiplexed and converted to a single-line DWDM interface, without accessing the
Cisco ONS 15454 shelf cross-connect fabric. A single card multiplexes up to two Gigabit Ethernet, 1-Gbps Fibre Channel or FICON services
as well as a single 2-Gbps Fibre Channel or FICON service and up to eight ESCON services. The interface to the client is through a variety of
Small Form-Factor Pluggable (SFP) optics modules, facilitating a wide service mix, including Gigabit Ethernet, 1-Gbps or 2-Gbps Fibre
Channel, FICON and ESCON, and different fiber types (single-mode and multimode), wavelengths (850 and 1310 nanometers [nm]), and fiber
reach (short reach for intraoffice, intermediate reach for short haul, etc.). The SFP optics modules are equipped with LC connectors to enable
high-density placement on the card. Because the 2.5-Gbps multiservice aggregation card incorporates both client and DWDM line interfaces
into a single card, up to 12 cards can be deployed in the Cisco ONS 15454 platform.
The DWDM line interface provides one long-reach or long-haul, ITU-compliant, 100-GHz spaced optical interface. The DWDM output line
interface is tunable across four adjacent 100-GHz wavelengths, facilitating support for 32-channel DWDM networks using only eight separate
cards. At each wavelength, the 2.5-Gbps multiservice aggregation card wavelength is offered in protected or unprotected versions. The
protected version includes a second DWDM line output or input, helping enable optical line protection over a DWDM network.
The 2.5-Gbps multiservice aggregation card supports many carrier-class features and advanced capabilities including service flexibility,
ability to tune wavelengths, flexible protection mechanisms, management, storage-area network (SAN) extension beyond the metro, and
performance-monitoring capabilities outlined in the following sections.
Service Flexibility
The 2.5-Gbps multiservice aggregation card supports up to two Gigabit Ethernet, 1-Gbps Fibre Channel and FICON ports, as well as a single
2-Gbps Fibre Channel and FICON port and up to eight ESCON ports. The client interfaces can be mixed, allowing the user to efficiently and
cost-effectively aggregate data and storage protocols over a single wavelength.
Tunable Wavelengths
The 2.5-Gbps service aggregation cards operate on the 100-GHz ITU grid and are tunable across four adjacent 100-GHz channels per card. The
ability to tune the output ITU laser enables only eight discrete cards to cover the entire 32-wavelength plan, which reduces the burden of the
spares inventory by 75 percent.
Flexible Protection Mechanisms
The 2.5-Gbps multiservice aggregation card provides flexible protection capabilities for both client and DWDM line interfaces, enabling a
wide variety of network configurations required to deliver the various service-level agreements (SLAs) required by the customer application
(Table 1).
