Cisco 2-Port Gigabit Ethernet Shared Port Adapter
The Cisco 2-, 5-, 8-, and 10-Port Gigabit Ethernet SPAs are available on high-end Cisco routing platforms, offering the benefits of network scalability with lower initial costs and ease of upgrades. The Cisco SPA/SIP portfolio continues the company’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.
Gigabit Ethernet interfaces are commonly used for interconnecting routers or other devices within a central office or data center or in a metropolitan-area network (MAN). Cisco offers an extensive variety of 1000BASE-X Gigabit Ethernet SPAs to meet customers’ needs for various applications. With Cisco Gigabit Ethernet SPAs, you can mix-and-match SPA ports with other types of interfaces in the same slot. Each SPA provides standards-based Gigabit Ethernet implementation for compatibility and interoperability.
In addition to the two Small Form-Factor Pluggable (SFP)-based Gigabit Ethernet ports, two additional built-in RJ-45 ports are provided on the 2-port Gigabit Ethernet SPA, Version 2. A combination of these Gigabit Ethernet ports is permitted, limited to a total of 2 Gigabit Ethernet ports (both copper, both optical, or one copper and one optical).
The Cisco Gigabit Ethernet SPAs can be used in multiple applications, including:
• Inter- and intra-point of presence (POP) aggregation
• Residential triple play (data, voice, and video)
• Metro Ethernet services
• Converged residential and business services
• Internet peering
