Samtec FireFly mid-board interconnect module transparently transports PCIe signals over 100m of optical cable

Xcell Daily has covered the Samtec FireFly mid-board interconnect system several times but now there’s a new 3.5-minute video demo of a PCIe-specific version of the FireFly optical module. In the video demo, FireFly optical PCIe modules convey PCIe signals between a host PC and a video card over 100m of optical fiber in real time. The video passed over this link works smoothly. That’s quite a feat for a small module like the FireFly and it creates new possibilities for designing distributed systems.

 

The PCIe-specific version of the Samtec FireFly module handles PCIe sidebands and other PCIe-specific protocols. These modules match up well with the PCIe controllers found in Xilinx UltraScale and UltraScale+ devices and many 7 series FPGAs and Zynq SoCs. As Kevin Burt of Samtec’s Optical Group explains, the mid-board design of the FireFly system allows you to locate the modules adjacent to the driving chips (FPGAs in this case), which improves signal integrity of the pcb design.

 

Here’s the Samtec video:
