Avago launches first 8Gb/s SFP transceiver for Fibre Channel

Avago Technologies of San Jose, CA, USA has announced the availability of what it claims is the industry’s first 8Gb/s SFP optical transceivers for Fibre Channel applications. Due to its transmitter optical and electromagnetic interference (EMI) performance, the AFBR-57D5APZ doubles the bandwidth of previous Fibre Channel SFP optical transceivers. The new transceiver is also compliant with industry SFP + multi-service agreements and enables the production of standards-based 8Gb/s storage-area network (SAN) switches, storage arrays, host bus adapters and tape drives.

“Our high-performance 8Gb/s Fibre Channel optical transceivers are already in 8G storage products shipping today,” says David D’Andrea, director of marketing for Avago’s fiber optic products division. “We’ve aggressively increased our share in the storage market, with nearly two million 4Gb/s transceivers sold in the last 12 months,” he adds. “Our internal VCSEL (vertical-cavity surface-emitting laser) source supports a steady and reliable supply of SAN products.” Avago is also working on 16Gb/s technologies.

The AFBR-57D5APZ is designed to be compliant with FC-PI-4 standards over multimode optical fiber at signaling rates from 8.5Gb/s to 2.125Gb/s without the need for external rate select inputs. It provides real-time temperature, supply voltage, laser bias current, laser average output power and received input power diagnostic information. Its digital diagnostic interface also adds the ability to disable the transmitter, monitor for transmitter faults and monitor for receiver loss of signal.

The new transceiver is available in link lengths up to 150m for 8.5Gb/s; up to 300m at 4.25Gb/s; and up to 500m at 2.125Gb/s. It leverages all standard features and capabilities of Avago’s widely adopted 4G SFP modules, including DMI and RoHS compliance. Pricing begins at $100 in high volumes.
