The NVIDIA Mellanox MFA1A00-E010 is a 10m active optical cable for EDR InfiniBand at 100Gb/s, with QSFP28 connectors on both ends. It links EDR InfiniBand switches and ConnectX adapters across racks and rows, where passive copper cables, which reach only a few meters at 100Gb/s, are too short.

An active optical cable has optics built into each connector and joined by fiber, so you don't need separate transceivers to buy or match. The cable is thinner and lighter than copper, which keeps cable trays and rack doors clear, and the LSZH jacket suits data center installations. It plugs straight into EDR switches such as the SB7700, SB7800 and SB7890, and into ConnectX-4, ConnectX-5 and ConnectX-6 adapters running EDR InfiniBand.

The E in the part number means EDR InfiniBand. For 100GbE Ethernet, choose the MFA1A00-C010 instead.
