Fiber Optics Bridge Card V1 – Obsolete

Guzik Test and Measurement has develop a general purpose, fiber optics to PCIe® bridge card with built in FPGA processing and on-board memory buffer. The cards are typically used in pairs connected via an optical fiber link, with one card connected to a computer CPU host on one side of the link, and the other to PCIe® devices, such as high performance GPU cards or RAID storage on the other side, or acting as its own PCIe® endpoint for high-performance DAQ systems and open-FPGA general purpose processors.

An Altera Stratix V GS FPGA (5SGS) is connected via x8 Gen3 PCIe® interface to the card edge. The optical link consists of 12 bi-directional optical lanes with total user data bandwidth greater than 20 GB/s (169.2 Gb/s). The optical conversion is provided by a miniature on-board optical Firefly engine connected to the FPGA. A large on-board 32 GB of DDR3 SDRAM memory with total bandwidth of 25 GB/s is provided to match the optical link data throughput.
