MUNICH, Germany, Nov. 4 -- Infineon Technologies announced today it has demonstrated the first 10 Gigabit Ethernet XPAK-compliant transceiver module operating over 300 meters of low-bandwidth multimode fiber. The transceiver used a 1310-nm laser with electronic dispersion compensation (EDC) technology to extend the distance over which 10 Gigabit Ethernet data can be transmitted error-free. XPAK is a specification authored by a number of companies to build a small form factor 10-Gigabit module that is faceplate pluggable and is mounted on the top of a customer printed circuit (rather than requiring a cutout in the board). Infeon said the demonstration proves the feasibility of using single-laser transceivers for high-speed transmission over the installed low-bandwidth fiber infrastructure. "The use of EDC-enabled transceivers to upgrade networks without replacing fiber will also help accelerate adoption of 10 Gigabit Ethernet technology, with its greater bandwidth," the company said in a statement. "The EDC-equipped Infineon XPAK optical module has shown the ability to transmit 10 Gb/s data over up to 300 meters of virtually any grade of legacy multimode fiber." It cited an IEEE 802.3 High Speed Study Group report that found more than 80 percent of the world's current enterprise fiber infrastructure is based on this type of low-bandwidth multimode. First samples of Infineon's XPAK modules with integrated EDC will be available in the first half of 2004. For more information, visit: www.infineon.com
