PXH842 high level specification 

The PXH842 is a PCI Express Gen3 x16 Transparent Host and Target card for PCIe IO expansion applications.  Dolphin offers various 
configurations of this board to support various installations of FireFly modules.  The standard product is a dual x8 configuration that 
supports a x16 or dual x8 configurations. 

Product variants 

The card can be ordered with different FireFly optical engines mounted depending on your use case and requirements:
