NVIDIA Mellanox MFA1A00-Exxx are QSFP28 VCSEL-based (Vertical Cavity Surface-Emitting Laser) active optical cables designed for use in InfiniBand 100Gb/s EDR (Enhanced Data Rate) systems. 

MFA1A00-Exxx AOC offers high port density and configurability, and a much longer reach than passive copper cables in the data centers. Since the AOC is hot pluggable, it is easy to install and replace.

MFA1A00-Exxx offers selectable retiming per lane for both its optical transmitters and receivers for the 25Gb/s rate, but the AOC also supports lower bit rates without retiming. The transmitters have programmable input equalizers and input squelch function, while the receivers have programmable output amplitude and pre-emphasis.

These unique-quality active-fiber cable solutions provide power-efficient connectivity for data center interconnects. They enable higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers. 

Rigorous production testing ensures the best out-of-the-box installation experience, performance and durability.
