The gateways also supports FDR10, a non-standard InfiniBand data rate, where each lane of a 4X
port runs a bit rate of 10.3125 Gb/s with a 64b/66b encoding, resulting in an effective bandwidth
of 40 Gb/s.
FDR10 supports 20% more bandwidth over QDR using the same QSFP cables/connectors.
Both FDR and FDR10 support Forward Error Correction (FEC), as described in IEEE 802.3ap
chapter 74.
FDR and FDR10 are only guaranteed to work with approved Mellanox Cables.
