Avago unveils first 14Gbps per lane transceivers
At this week’s Optical Fiber Communication Conference (OFC 2011) in Los Angeles (8–10 March), Avago Technologies has announced sample availability for two new fiber-optic transceivers with 14.025Gbps throughput per lane (exhibited in booth number 2001).
The new SFP+ transceiver addresses 16 Gigabit Fiber Channel switches, host bus adapters, RAID controllers and tape drives, as well as inter-switch and inter-chassis aggregated links. The four-channel QSFP+ transceiver targets switch and router interconnects for datacoms and telecoms, data aggregation and backplane applications, and proprietary protocol and high-density link applications. The modules are the first in Avago’s 14Gbps optical transceiver platform, offering increased port density for systems compared to 8Gbps Fiber Channel optics.
“Avago leverages a unique collection of core technology and design expertise to bring new performance standards and innovative form-factors first to market, as is the case with our 14Gbps platform,” claims Victor Krutul, director of marketing for the Fiber Optics Products Division. “Our new 16 Gigabit Fiber Channel SFP+ and four-channel QSFP+ modules are already winning designs with top systems manufacturers in high-density applications,” he adds. “We are looking to build on this early success by adding more new solutions to our 14Gbps platform.”
The new transceivers incorporate Avago’s 850nm vertical-cavity surface-emitting laser (VCSEL) technology and PIN detector technology, ensuring that the multi-rate SFP+ module is compliant with FC-PI-5 and 16/8.5/4.25 Gigabit Fiber Channel specifications. The SFP+ module’s transmitter and receiver can operate at different data rates, as is often required during Fiber Channel speed negotiation.
The hot-pluggable QSFP+ module is compliant with the QSFP+ SFF-8436 specification, and reduces power dissipation per lane by 50% compared with 8Gbps Fiber Channel technology. Avago says that its 14Gbps platform also has the potential to address Infiniband FDR applications.
The 14Gbps SFP+ and QSFP+ transceiver modules are currently sampling, with production expected in mid-2011.
