The FMC PCIe Carrier is an FMC carrier that can hold one FMC card and an SFP connector. On the PCIe side it has a 4-lane interface, while the FMC mezzanine slot uses a low-pin count connector. This board is optimised for cost and is usable with most of the FMC cards designed within the OHR project (e.g. ADC cards, Fine Delay).
