Description
Cisco SPA-4XOC12-POS 4-Port OC-12c/STM-4 POS Shared Port Adapter
Overview
The Cisco 1-, 2-, and 4-Port OC-48c/STM-16c POS/RPR SPAs are available on high-end Cisco routing platforms and offers the benefits of network scalability with lower initial costs and easy upgrades. The SPAs continues the Cisco focus on investment protection along with consistent feature support, broad interface availability, and leading-edge technology. The SPAs allow different interfaces (POS, ATM, etc.) to be deployed on the same carrier card.
The Cisco 1-, 2-, and 4-Port OC-48c/STM-16c POS/RPR SPAs use Small Form-Factor Pluggable (SFP) interfaces. SFP modules are available in short-reach (2 km), intermediate-reach (15 km), and long-reach (80 km) optics.
Specifications
The Cisco SPA-4XOC12-POS 4-Port OC-12c/STM-4 POS Shared Port Adapter is a network interface module designed for high-end Cisco routing platforms.
-
- The Cisco SPA-4XOC12-POS provides four channelized OC-12c/STM-4 ports per SPA.
- It supports Packet over SONET/SDH (PoS) for mesh fiber networks and Resilient Packet Ring (RPR) for ring fiber topologies.
- Complying with the IEEE 802.17 RPR standard, it 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 voice, video, and data services. It enhances speed-to-service revenue and offers quality of service (QoS) features while reducing overall cost of ownership.
- Applications: The Cisco SPA-4XOC12-POS can be used in various applications, including access and aggregation, WAN uplinks, and internet peering.

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.
