Cisco's Gigabit Ethernet Family of Solutions (PA-GE) for Cisco 7200VXR and 7304 Series Routers
Cisco Gigabit Ethernet solutions (PA-GE) for the Cisco 7200VXR and 7304 series routers provide high-capacity Local Area Network (LAN) connectivity for enterprise edge, campus LAN and service provider networks with high-density, high-throughput requirements.
The following Gigabit Ethernet interface is available for the Cisco 7200VXR and the Cisco 7304 series routers:
Single Port Gigabit Ethernet Port Adapter (PA-GE)
The single port Gigabit Ethernet Port Adapter (PA-GE) provides a Gigabit Ethernet connection for the Cisco 7200 and Cisco 7304 series routers. This port adapter (PA), which offers moderate performance, is suitable for campus, enterprise edge and wide-area network (WAN) aggregation applications. When used on the campus, the Cisco 7200 and Cisco 7304 series routers with the PA-GE connects the enterprise WAN to the Gigabit Ethernet campus backbone. At the enterprise edge, the PA-GE connects the WAN to the Gigabit Ethernet campus backbone. When the Cisco 7200 series router is used for WAN aggregation, the PA-GE provides intra-pop connectivity between the router and high-speed WAN core devices, such as the Cisco 12000 series router. The PA-GE may be inserted into any open port adapter slot on Cisco 7200VXR routers while the PA-GE is supported on the Cisco 7304 by way of the Carrier Card.
Gigabit Ethernet Interface Processor (GEIP) and Enhanced Gigabit Ethernet Interface Processor (GEIP+)
The single-port Gigabit Ethernet Interface Processor and the Enhanced Gigabit Ethernet Interface Processor, both based on Versatile Interface Processor (VIP) technology, provide a Gigabit Ethernet connection for the Cisco 7500 series router. These interface processors (IP) are suitable for campus, enterprise edge and WAN aggregation applications. When used on the campus, the Cisco 7500 series router with the GEIP or GEIP+ connects the enterprise WAN and/or legacy LANs, such as FDDI or Token Ring to the Gigabit Ethernet campus backbone. At the enterprise edge, the GEIP or GEIP+ connects the WAN to the Gigabit Ethernet campus backbone. When the Cisco 7500 series router is used for WAN aggregation, the GEIP or GEIP+ provides intra-pop connectivity between the router and high-speed WAN core devices, such as the Cisco 12000 series router.
The GEIP and GEIP+ differ primarily in their performance. The GEIP+ provides up to 800 Mbps of aggregate throughput, while the GEIP performs at a more moderate level. In addition to performance, the GEIP+ is based on VIP4 technology, provided many benefits including error correcting code (ECC) circuitry for improved availability. The GEIP+ significantly extends Gigabit Ethernet performance on the Cisco 7500 series router, providing high performance solutions for Gigabit uplinks from the enterprise edge and data center, as well as in service provider points of presence.
The Gigabit Ethernet modules for the Cisco 7200 and 7500 series are IEEE standards compliant and support full duplex operation.
Gigabit Interface Converters (GBIC)
A GBIC is a removable transceiver that provides an adaptation of the Interface Processor to a variety of physical layer Gigabit Ethernet cabling. Different model GBICs support different media types, wavelengths and distances, providing for highly flexible deployments. The GE interfaces can be configured for 1000BASE-SX (short wavelength), 1000BASE-LX (long wavelength), 1000BASE-LH (long haul), and 1000BASE-ZX (extended wavelength) applications. GBICs within the GE interfaces are hot-swappable, minimizing network disruption when changing media types.
All modules can be configured with a choice of shortwave (SX), longwave/long haul (LX/LH), or extended wavelength (ZX) GBIC. GBICs are selected as an option when the GE interface is ordered. The GE assembly for each interface is a field replaceable unit (FRU).
