40- and 100GbE transmission over multimode fiber

摘要

The explosion in demand for bandwidth and, consequently, for high-capacity computing, is driving an urgent need for higher Ethernet network speeds. Several factors contribute to this, including broadband penetration fueled by video-rich content, data-center demands, and exponential growth in supercomputer and R&D computing activities. Different application spaces will benefit from increased transmission speeds. For this reason, the IEEE 802.3ba Task Force is working to develop 40-and 100-Gigabit Ether- net (GbE) standards simultaneously. The 40-Gbit/ sec standard will support an immediate need in the server market. The 100-Gbit/sec rate is needed for core switching and routing applications, network aggregation, and high-performance computing. As in the past, the IEEE Task Force will leverage existing media and technology to balance cost and performance.
