-- Gigabit Ethernet -- 10GbE switch chips -- GbE-over-Copper PHYs -- 10GbE PHYs for copper and optical media -- 10GBase-KR backplane transceivers -- Power-over-Ethernet (PoE) controllersIn addition to 10GbE growth, the firm reports that the infrastructure market for GbE silicon grew 15 percent in 2007, and expects combined GbE/PHY revenue to grow about 12 percent in 2008, with switch-plus-PHY revenue slowing in 2009 and beyond. As the data center transitions to 10GbE, thousands of servers will require connections. With virtualization rapidly becoming a mainstream technology, server usage and I/O bandwidth requirements will further increase. Moreover, LAN aggregation will be a critical application for 10GbE switches. These trends will drive the need for higher port counts, Layer 3 switching, and security features, according to the report. In 2009, the combination of 10GbE switch chips, optical PHYs, and 10GBase-T adoption should make 10GbE a meaningful portion of overall Ethernet switch/PHY revenue. Although Broadcom is the leading supplier of Gigabit Ethernet components, The Linley Group believes it has not secured its place as the dominant supplier for 10GbE products. Solarflare and Aquantia offer 10GBase-T PHYs with the lowest power dissipation, while Fujitsu is the first vendor to integrate 10Gbps serdes in its 10GbE switch, and AMCC was the first vendor to sample a 10GBase-KR transceiver for the backplane. Competitors looking to challenge Broadcom must move quickly and aggressively to build a leading set of 10GbE components.
