The Cisco 1-Port OC-192 POS/RPR SPA is a network interface module designed for high-end Cisco routing platforms.

Overview: The Cisco 1-Port OC-192 POS/RPR SPA combines POS (Packet over SONET/SDH) for mesh fiber networks and Resilient Packet Ring (RPR) for ring fiber topologies. It complies with the IEEE 802.17 RPR standard and also supports the Spatial Reuse Protocol (SRP) for compatibility with existing Dynamic Packet Transport (DPT)/RPR networks.

Features and Benefits:

• • Modularity: The SPA is highly modular and flexible, allowing different interfaces (packet over SONET/SDH, ATM, Ethernet, etc.) to be deployed on the same interface processor. It provides 10-Gbps Small Form-Factor Pluggable (XFP) interfaces in addition to fixed interfaces, with configurations available to support multiple optical reaches from 300 meters to 80 kilometers.
  • Service Intelligence: The Cisco I-Flex approach combines shared port adapters (SPAs) and SPA interface processors (SIPs), providing an extensible design that enables service prioritization for data, voice, and video services. It enhances speed-to-service revenue and offers quality of service (QoS) features while reducing overall cost of ownership.
  • Applications: The Cisco 1-Port OC-192 POS/RPR SPA can be used in various applications, including access and aggregation, WAN uplinks, and internet peering.
