The Cisco 8-Port OC-12 POS shared port adapter (SPA) is available on high-end Cisco Systems routing platforms offering the benefits of network scalability with lower initial costs and ease of upgrades. The Cisco SPA/SIP portfolio continues the Cisco focus on investment protection along with consistent feature support, broad interface availability, and the latest technology. The Cisco SPA/SIP portfolio allows different interfaces to be deployed on the same interface processor.
A key feature of these SPAs is the multi-rate 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. The Cisco 8-Port OC-12 POS SPA provides support for Small Form-Factor Pluggable (SFP) interfaces.
