What is the advantage of Gigabit Ethernet over copper vs optical fiber?
Existing Ethernet networks are 98% Category-5 cabling. National Semiconductor”s Gigabit Ethernet products provide a 10x network bandwidth improvement over these existing 10/100 Mb/s networks, using the already installed cabling, avoiding costly fiber optic installations. National Semiconductor”s Gigabit Ethernet products are also interoperable w/ existing 10 Mb/s Ethernet, and 100 Mb/s Fast Ethernet networks, allowing seamless network upgrades.
