The Cisco 1-Port 10-Gigabit Ethernet LAN/WAN-PHY SPA is 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 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. Within a central office or data center or in a metropolitan-area network (MAN), 10-Gigabit Ethernet interfaces are commonly used to interconnect routers or other devices. The Cisco 1-Port 10-Gigabit Ethernet LAN/WAN-PHY SPA supports a broad range of customer needs and applications. With this SPA, users can mix and match SPA ports with other types of interfaces in the same slot. The Cisco 1-Port 10-Gigabit Ethernet LAN/WAN-PHY SPA introduces 10-Gigabit Ethernet connectivity based on IEEE 802.3ae standards for compatibility and interoperability in configurable WAN and LAN modes, with a single-height modular I/O form factor.
