Gigabit Ethernet interfaces are commonly used to interconnect 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 GE SPAs to meet customer needs for various applications. With Cisco GE SPAs, users 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.
