Introduction
NVIDIA® MFA1A00 is a QSFP28 VCSEL-based (Vertical Cavity Surface-Emitting Laser) active optical cable (AOC) designed for use in 100Gb/s InfiniBand (IB) EDR (Enhanced Data Rate) and Ethernet systems.
The MFA1A00 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.
The MFA1A00 has a standard SFF-8665 compliant QSFP28 port on the electrical side towards the host system. It contains four multi-mode fibers (MMF) optic transceivers per end, each operating at data rates of up to 26Gb/s.
The MFA1A00 offers selectable retiming per lane for both its optical transmitters and receivers for the 25-26Gbp/s rates, 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.
NVIDIA’s unique-quality active fiber cable solutions provide power-efficient connectivity for data center interconnects. It enables 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.
