Infineon Extends 10 GigE over 300 Meters of Multimode Fiber

Infineon Technologies announced a 10 Gigabit Ethernet (GbE) XPAK-compliant transceiver module capable of operating over 300 meters of low-bandwidth multimode fiber. The XPAK optical transceiver uses a 1310 nm laser with EDC (electronic dispersion compensation) technology to extend the distance over which 10 GbE data can be transmitted error-free. Infineon said its demonstration proves the feasibility of using single-laser transceivers for high-speed transmission over the installed low-bandwidth fiber infrastructure. The EDC technology compensates for dispersion and other impairments that cause inter-symbol interference and performance degradation. Without EDC, end-users need to either deploy high-cost, high-bandwidth multimode fiber to reach 300 meters at 10 Gbps, or use a solution that requires multiplexing four separate lasers of different wavelengths, which results in greater complexity, higher power dissipation, increased costs and reduced reliability. First samples of Infineon’s XPAK modules with integrated EDC will be available in the first half of 2004.
