When used with single-mode optical fiber, 10-Gigabit Ethernet has an operating range of up to
40 miles. This operating range and its very high speed make 10-Gigabit Ethernet a viable
alternative for linking large corporate LANs and for connecting datacenters, server farms, and
storage area networks (SANs) within a campus or metropolitan area. By using Ethernet from end
to end, such deployments can reduce costs, simplify training and management, and avoid
potential problems with latency and other complications arising from converting between the
Ethernet and Internet Protocol (IP).
Deploying 10-Gigabit Ethernet gives Enterprises an edge over their competition by being able to
support their existing data-intensive infrastructures while easing the burden on highly aggregated
links with large over-subscription ratios. The deployment also quickly accommodates new
initiatives in high-performance computing, server clustering, SANs, disaster recovery, streaming
media, and multi-site collaboration. Additionally, by using 802.1p and 802.1q, 10-Gigabit
Ethernet can deliver guaranteed levels of latency, jitter, and bandwidth, allowing Enterprises to
integrate voice over IP, video, and other multimedia traffic on the network.
With the growing number of bandwidth-intensive applications and the potential for 1Gbps links
to desktops or small workgroups, there is an increasing need for 10Gbps connections to carry
traffic on LAN backbones and elsewhere in the corporate network. Enterprises can feel
comfortable deploying 10-Gigabit Ethernet now to meet these needs, knowing that it will work
with existing Ethernet installations and bring reductions in operating costs without requiring any
costly overhauls or high levels of sophistication.
