The first 8Gbit/s small form-factor pluggable (SFP) optical transceiver for Fibre Channel applications has been announced by Avago Technologies Ltd. The AFBR-57D5APZ transceiver doubles the bandwidth of previous Fibre Channel SFP optical transceivers. It is compliant with industry SFP + multi-service agreements and enables the production of standards-based 8Gbit/s SAN switches, storage arrays, host bus adapters and tape drives.

"Our high-performance 8Gbit/s Fibre Channel optical transceivers are already in 8G storage products shipping today," said David D'Andrea, director of marketing for the fiber optic products division of Avago. "With high-quality products and superior service, we've aggressively increased our share in the storage market with nearly two million 4Gbit/s transceivers sold in the last twelve months. The introduction of our 8Gbit/s transceiver and work on 16Gbit/s technologies demonstrates Avago's continued leadership in the storage industry. Further, our internal vertical-cavity surface-emitting laser source supports a steady and reliable supply of SAN products."

The AFBR-57D5APZ is designed to be compliant with FC-PI-4 standards over multimode optical fiber at signaling rates from 8.5Gbit/s to 2.125Gbit/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 transceivers are available in link lengths up to 150m for 8.5Gbit/s; up to 300m at 4.25Gbit/s.; and up to 500m at 2.125Gbit/s. It leverages all standard features and capabilities of Avago's widely adopted 4G SFP modules, including DMI and RoHS compliance.

Avago's AFBR-57D5APZ is available now, with prices beginning at $100 in high volumes.
