Compare Cisco (NM-1GE) Expansion Module to Cisco Line Card (8OC3/POS-SM-RF) Expansion Module

The single-port Cisco Gigabit Ethernet Network Module (part number NM-1GE) provides Gigabit Ethernet optical and copper connectivity for access routers. The module is supported by the Cisco 2691, Cisco 3660, Cisco 3725, and Cisco 3745 series routers. This network module has one gigabit interface converter (GBIC) slot to carry any standard copper or optical Cisco. The flexibility to use different GBICs allows for making a choice depending on various factors, such as distance, cost, existing infrastructure, future expansion plans, and requirements.??The Cisco Gigabit Ethernet Network Module enables branch offices to cost-effectively utilize high-speed uplinks in a variety of environments. The enhanced performance allows customers to enable new applications and services as well as providing greater capacity for existing inter-VLAN routing and bridging capabilities. Additionally, branch offices will now have the opportunity to connect to metropolitan-area networks (MANs). Cisco IOS Sof... Less

The exponential growth in IP data traffic is forcing service providers to upgrade their Point-of-Presence (POP) with higher performance and scalable Layer 3 backbone switches and routers. In order to keep costs down for their network expansions, Internet service providers (ISPs) are looking for intra-POP connectivity between the multigigabit backbone routers and edge routers using high-port density OC3/Packet-over-SONET/SDH (PoS) interfaces.??This card offers a high-density intra-POP connectivity between the Cisco 12000 GSR and other lower-end routers (such as the Cisco 7500 router or Cisco 12008 GSR). Service providers will benefit from this high-density OC-3/PoS card by eliminating or reducing the need to implement and operate an intermediate layer of networking equipment between the Cisco 12000 GSR and other routers.
