Avago first to market with 10GbE SFP+ SR transceiver

Avago Technologies of San Jose, CA, USA has announced availability of what it claims is the industry’s first 10 Gigabit Ethernet (10GbE) SFP+ SR (short reach) optical transceiver.

Shipping in production volumes (with pricing beginning at $200), the 850nm VCSEL-based 10Gb/s AFBR-700SDZ SFP+ (small form-factor pluggable) transceiver with digital monitoring interface (DMI) is the first to bring new levels of speed and high-port density to next-generation networking equipment, the firm claims.

“The SFP+ form factor presents a tremendous opportunity for vendors to add port density and value to their networking products,” says David D’Andrea, director of marketing for the fiber-optic products division. “Avago is first out of the gate with its 10Gb/s SFP+ transceiver and our product is already qualified with multiple customers,” he adds. Avago was also first to release a production-ready 10Gb/s XENPAK LRM (long-reach multimode) transceiver (which dramatically increased bandwidth for networking applications), D’Andrea claims.

At the core of the 10Gb SFP+ transceiver is Avago’s own internally developed 850nm vertical-cavity surface-emitting laser (VCSEL) source. This uses technology from Avago’s 4G VCSEL design, which has undergone over 2 billion device hours of testing with no failures. The AFBR-700SDZ also uses multimode fiber, which enables the SFP+ transceiver to extend coverage up to 300m.

The new optical transceiver supports the SFF-8431 specification for enhanced 10Gb/s SFP+ as well as the SFF-8472 specification for DMI in optical transceivers. This delivers real-time temperature, supply voltage, laser bias current, laser average output power and received input power information through a two-wire interface. The digital diagnostic interface also adds the ability to disable the transmitter, monitor for transmitter faults, and monitor for receiver loss of signal.

According to a recent report issued by market research firm IDC, installation of 10GbE ports will more than double from 1.4 million in 2007 to over 3 million by 2010. The application areas fueling this growth include networking switches and data communication equipment.
