Cisco SPA-4XOC3-POS-V2 4-Port OC3-c/STM-1c PoS Shared Port Adapter
Overview
The Cisco 2- and 4-Port OC-3 POS SPAs are available on high-end Cisco routing platforms,
offering the benefits of network scalability with lower initial costs and easy upgrades. The Cisco SPA/SIP portfolio continues Cisco’s focus on investment protection along with consistent feature support, broad interface availability, and the latest technology. The Cisco SPA/SIP portfolio allows deployment of different interfaces (packet over SONET/SDH [POS], ATM, Ethernet, etc.) on the same interface processor.
The Cisco 2- and 4-Port OC-3 POS SPAs are available with two or four Small Form-Factor
Pluggable (SFP) interfaces. SFP modules are available in multiple optical reaches from 2 to 80
kilometers (km).
Specifications
The Cisco SPA-4XOC3-POS-V2 4-Port OC3-c/STM-1c PoS Shared Port Adapter is a network interface module designed for high-end Cisco routing platforms.
-
- The Cisco SPA-4XOC3-POS-V2 combines Packet over SONET/SDH (POS) 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.
Key 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.
- 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 SPA-4XOC3-POS-V2 can be used in various applications, including access and aggregation, WAN uplinks, and internet peering.

The Cisco SPA/SIP portfolio allows different interfaces (Packet over SONET/SDH [POS], ATM, Ethernet, and so on) to be deployed on the same interface processor.
A key feature of these SPAs is the multirate operating mode support. This allows ports to be configured at OC-3 or OC-12 speeds. This gives the flexibility to configure some ports to run at OC-3 speeds, while the rest can run at OC-12 speeds. This requires different optics for different modes.
