The Cisco® I-Flex design combines shared port adapters (SPAs) and SPA interface processors (SIPs), using an extensible design that enables service prioritization for voice, video, and data services. Enterprise and service provider customers can use the improved slot economics resulting from modular port adapters that are interchangeable across Cisco routing platforms. The I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors, which deliver line-rate performance. I-Flex enhances speed-to-service revenue and provides a rich set of quality-of-service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership. This data sheet contains the specifications for the Cisco 1-Port 10GE Tunable WDM-PHY Interface SPA.
Product Overview
The Cisco 1-Port 10GE Tunable WDM-PHY SPA provides a tunable optical interface that can be used to connect directly to dense wavelength-division multiplexing (DWDM) transport systems, eliminating the need for an optical transponder. The Tunable WDM-PHY SPA provides full 80-channel tunability with 50-GHz spacing across the C band and meets ITU specifications. It supports G.709 framing for robust connectivity and SONET-like operations, administration, maintenance, and provisioning (OAM&P) as well as generic forward error correction (GFEC) for regional applications. For long-haul application support, the high-gain enhanced forward error correction (EFEC) functionality is provided, which can extend optical reach up to 2000 km without optical-electrical regeneration.
The 10GE Tunable WDM-PHY SPA is part of the Cisco IP-over-DWDM solution portfolio. Service providers benefit from IP-over-DWDM integration through faster service provisioning, increased reliability, and simplified network management. Integrated DWDM transponders simplify the network by reducing the number of network elements and also scale at a lower total cost to reduce bandwidth cost. Finally, IP-over-DWDM solutions allow service providers to more cost-effectively use the rich QoS and IP intelligence of Cisco routers in their transport networks.
The 1-Port 10GE Tunable WDM-PHY SPA allows the router to connect directly to an optical ring using either a passive DWDM line system or reconfigurable optical add-drop multiplexers (ROADMs), allowing customer traffic to be carried separately and securely on a single DWDM wavelength. It eliminates the need for bulky and expensive optical transponders. It simplifies network operation by allowing DWDM optical functions and wavelengths to be managed as part of the IP network, reducing the number of network elements and simplifying network management.
Combined with the Cisco ONS 15454 Multiservice Transport Platform (MSTP), the 1-Port 10 Gigabit Ethernet Tunable WDM-PHY SPA provides a powerful solution for bringing IP intelligence to metropolitan and core optical transport networks.
Metro-regional DWDM and long-haul applications are both possible with this product. Long-haul applications of up to 2000 km are supported with the use of the built-in EFEC support.
Features and Benefits
The 1-Port 10GE Tunable WDM-PHY SPA is a primary element in the Cisco IP over DWDM solution, integrating an OTN-compliant (Optical Transport Network) and ITU-compliant interface directly onto the router. Furthermore, as a SPA, the customer also gains all the benefits of Cisco I-Flex modularity: improved slot economics, interface interchangeability across platforms, and investment protection. Table 1 summarizes the features and benefits of this product.
